SEMINAR CLASS #5 - Week of 4/29/18; "Multiple Dwellings" FFP - MD's, TB - Tools #2,3,7 (DS #17,18), 32, AUC 349 Instructor: BC Kenny Ruggiero

Question 1

1. During a recent study group session members were discussing some of terms listed in the glossary section of the various bulletins. The discussion centered around the importance of reading the glossary since examiners can ask questions from the glossary section of the bulletins. Which statement made below is not entirely correct? Glossary

A. A reversed roof is a roof which is raised above the roof beams and supported by 2” x 4”s. The extent to which it is raised varies so as to provide proper drainage on the roof.

B. Fire stopping is the closing of all concealed draft openings to form a barrier against the spread of fire with non-combustible materials.

C. Coaming is a raised frame around a floor, roof opening, or scuttle to keep water from running in.

D. A back stretch is a procedure in which an Engine is placed close to a fire and receives its water supply through a hose line stretched between the engine and a hydrant.

Answer 1

1. D

Back stretch A method of stretching a hoseline. Members pull off sufficient hose at the location of the fire; engine then proceeds to the hydrant. The hose peels off the back of the engine as it travels to the hydrant.

Question 2

2.  After  operating  at  an  all  hands  fire  in  an  old  law  tenement  (OLT)  in  Manhattan,  the  Captain of  E-99  made  the  following  statements  about  old  law  tenements.  He  was  incorrect  in  which statement  below?  Section  2.1
A.  OLT's  are  3  to  7  stories,  20'  to  25'  wide,  50'  to  85'  deep,  and  are  class  3  non  fire  proof construction  using  brick  walls,  wood  floor  beams,  and  wood  floors.
B.  The  stairway  to  the  cellar  is  by  way  of  an  exterior  stair  and  the  first  floor  (cellar  ceiling)  is fireproof  construction  and  unpierced.
C.  When  the  building  has  4  windows  per  floor  and  no  front  fire  escape,  it  usually  indicates  2 railroad  flats  with  a  rear  fire  escape.  Railroad  flats  are  those  apartments  which  extend  from  the front  of  the  building  to  the  rear.
D.  When  the  building  has  4  windows  per  floor  and  a  front  fire  escape,  it  usually  indicates  3 or 4  apartments  per  floor  with  another  fire  escape  in  the  rear.

Answer 2

2. B

Stairway to the cellar is located inside the building, usually beneath the interior stairway.

Question 3

3. During a drill about new law tenements (NLT) and non-fire proof multiple dwellings (NFPMD) members were discussing firewalls and fire proof partitions used in the construction of these buildings. These firewalls will have a different termination points depending on when the building was built. Which choice below is incorrect regarding firewalls in NLT and NFPMD construction? Sections 2.2,2.3,2.4.
   A. In NLT’s built between 1916 and 1929 the fire proof partitions only go as high as the ceiling of the top floor.
   B. In a NFPMD built between 1930 and 1940 firewalls were required to be carried to the underside of the roof boards.
   C. In a NFPMD built after 1940 firewalls were required to be carried above the roof line.
   D. In a NFPMD built on or after 4/18/1929 the size of the area to be enclosed by firewalls is 3000 sq/ft. In NLT’s built between 1916 and 1929 the floor areas were required to be broken up into areas of 2500 sq/ft. or less.

Answer 3

3. C
   Between 1930 and 1940, firewalls were required to be carried to the underside of the roof boards, and after 1940, to the top of the roof boards. These changes were designed to effectively reduce the size of the cockloft and limit fire spread.

Question 4

4. Lieutenant Costanza is working a day tour in E-99 and has just arrived, along with L100, at a fire in an old law tenement. The fire is on the 2nd floor in apartment 2F, in the front of the building. There is a heavy smoke condition coming from the 2nd’ floor windows and a person is on the fire escape on the 3rd floor directly above the windows where the smoke is coming from. The person is trying to come down the fire escape and is screaming for help. In this situation Lt. Costanza would be correct to give which order below? Section 3.2.2, 4.1.4
   A. Order the 1 line stretched to the 2nd floor and extinguish the fire in apartment 2F.
   B. Have his members operate the 1st line from the street to protect the person on the fire escape.

Answer 4

4. A

Flame not smoke

3.2.2 In most cases, the first line is stretched via the interior stairs to the location of the fire. The purpose of this line is to protect the primary means of egress for occupants evacuating the building and to confine and extinguish the fire. An exception to stretching the first line up the interior stairs may be made when flame is issuing from windows opening onto the fire escape and endangering people trying to come down the fire escape. In this case, the first line may be operated from the street to protect people on the fire escape. A second line should be promptly stretched to the interior of the building. If the entrance door to the building is self-closing and equipped with a locking device, the first member entering the building should use a chock, rug or other means of preventing the door from locking and thereby delaying other members trying to enter the building.

Question 5

5. As a general rule, outside streams should not be directed into occupied buildings. How ever in some cases, such as heavy fire in a store, an outside stream may be used in an occupied building. Only the incident commander may order the use of outside streams. The incident commander must be a Battalion Chief or above. Section 3.5.10 A C

A. Agree or B. Disagree

Answer 5

5. B

C. Only the Incident Commander may order the use of outside streams. This may be the first arriving officer. For example, the IC may order the deckpipe used for a store fire.

Question 6

6. At a recent fire on the 3rd floor of a 5 story isolated Old Law Tenement, four hose lines were stretched during the course of operations. Which hose line listed below was incorrectly stretched at this fire? Section 3.2.11
   A. The 1st hose line was stretched via the interior stairway to the 3rd floor. When the safety of the stairway was assured the 1®’ line was advanced into the apartment to extinguish the fire.
   B. The 2nd hose line at this fire was stretched via the interior stairway to back up the 1st line. When the 2nd’ hose line was not needed on the 3rd’ floor it was stretched to the 4th floor.
   C. The 3rd hose line at this fire was stretched via the interior stair to the 5th floor when there was a report that had extended to the 5”’ floor.
   D. The 4th hose line was stretched to the roof using a rope stretch on the front of the building to extinguish fire in the cornice which could not be reached from below.

Answer 6

6. C

The third line in the building should usually be stretched via the fire escape or rope stretch via a window. This is especially true in Old Law Tenements because the stairway is narrow and the stretching of a third line via the interior stairs would result in congestion and inability to move any of the hoselines.

Question 7

7.  Lt.  Wright  was  drilling  with  his  members  on  the  subject  of  ventilation.  Lt  Wright  told  his members  that  all  horizontal  ventilation  shall  be  controlled  and  coordinated  by  the  Ladder  Co.Officer  operating  in  the  area  to  be  vented.  Furthermore,  he  stated  that  discretion  should  be  used in  the  breaking  of  windows  in  apartments  not  involved  in  fire.  Efforts  should  be  made  to  open these  windows  when  possible.  Windows  should  be  opened  from  the  top  and from  the  bottom  to  allow  heat  and  smoke  to  vent  out  and  cool  air  to  enter  the  room. Section  3.3.3
A.  2/3  and  1/3
B.  3/4  and  1/4
C.  1/3  and  2/3
D.  1/4  and  3/4

Answer 7

7. A
8. 3.3 All horizontal ventilation shall be coordinated and controlled by the Ladder Company Officer operating inside the area to be vented (fire floor, floor above, etc.). Discretion should be used in the breaking of windows in apartments not involved in fire. Efforts should be made to open these windows where possible and necessary. Windows should be opened 2/3’s from the top and 1/3 from the bottom to allow heat and smoke to vent and cool air to enter the room. If there is a tolerable smoke condition and very little heat in the apartment and the windows cannot be opened, they should be left intact after a search has been made.

Question 8

8. You are a new Lieutenant working a day tour in E-99, which is a single engine, and is staffed with 5 firefighters. Just after lunch you get a run for a fire in a multiple dwelling. Enroute to the box the dispatcher tells you “it sounds like work” and “we are getting numerous calls”. The dispatcher also tells you the Battalion and the 1st due Truck are going to be delayed. Upon arrival you have fire issuing from the store on the 1” floor of a 5 story OLT, and also fire coming from the windows on the 2nd floor directly above the store. There are 2 people on the front fire escape on the 4th floor attempting to come down. You are the only unit on the scene.You would be correct in which choice below? Section 3.4.6,5.5.2

A. You transmit a 2nd alarm on arrival.
B. You transmit a 10-75 and request an extra engine and truck.
C. You transmit a 3rd alarm on arrival.
D. You transmit a 10-75 and request 2 additional trucks.

Answer 8

8. B
9. 4.6 The Incident Commander must keep in mind that fire in non-fireproof multiple dwellings can extend very quickly to the floors above and to the exposures. The IC must transmit special calls and/or greater alarms promptly when conditions warrant such actions. For a fire in an Old Law or New Law Tenement, special call an extra engine and truck for fire on two floors. If progress is not made on at least one floor in a short period of time, transmit a 2nd alarm. If fire is in a shaft extending into an exposure, transmit a 2nd alarm. If fire is extending into two exposures, transmit a 3rd alarm.
10. 5.2 Additional units: Because of the severe life hazard, height, area and combustible construction of these buildings, an additional engine company and ladder company (beyond a full 1st alarm assignment) should be called for a medium fire condition. That is, when it is anticipated that two lines will be required. When additional units have been special called, they should be given instructions, by radio, regarding positions, masks, extra hooks, etc. If two floors are involved, or at extensive cockloft fires, it will generally be necessary to transmit a 2nd alarm. The time that it takes 2nd alarm units to arrive must be considered under these conditions.

Question 9

9. During afternoon drill one day Lt. Smith made the following four points. He was only correct in which point? Section 3.5.9
   A. Gas meters are always found in the cellar and will never be found in the apartment itself or in a public hallway.
   B. Piping containing flammable gas is allowed to be run in a stair enclosure or a shaft containing a standpipe riser.
   C. If gas meters are burning the fire should be extinguished immediately and then the gas supply should be shut down.
   D. If gas is leaking without being ignited, the gas supply should be off and the area vented as much as possible.

Answer 9

9. D

If gas is leaking without being ignited, the gas supply should be shut off and the area ventilated as much as possible. Members should be moved away from the area of the leaking gas. Fog lines may be used for venting. A leak or break in the piping may be stopped or greatly diminished by stuffing rags, paper, etc., into the break.

Question 10

10. When operating at cellar fires in Old Law Tenements members should know which point below is not in accordance with FDNY procedures? Section 4.2

A. The 1”’ hose line stretched at a cellar fire in an OLT should be stretched to the cellar entrance door which is located inside the building under the interior stairway on the 1st floor.
B. The 1st hose line should remain at the cellar entrance door on the 1st floor to protect people coming down the stairs and to extinguish fire which may be extending up from the cellar via partitions, voids, and dumbwaiter shafts.
C. The 1st hose line should not advance down the cellar stairs if there is an outside entrance to the cellar at the front and rear of the building unless the fire is small to medium in size.
D. The 2nd hose line stretched should be advanced into the cellar by way of the front or rear entrance to the cellar.

Answer 10

10. C
11. 2.1 The first line should be stretched to the cellar entrance door which is located inside the building, under the interior stairway on the first floor. This line should remain at this position to provide protection for people coming down the stairway and to extinguish fire which may be extending upwards from the cellar via partitions, dumbwaiter shafts and other voids. This line should not be advanced down the cellar stairs if there is an outside entrance to the cellar at the front or rear of the building, unless the fire is minor.

Question 11

11. When operating at a store fire in an Old Law Tenement a 2 1/2” line must be stretched for medium or large fires since the store may involve a large amount of combustible material. A 2nd hose line should be immediately stretched to the floor above to extinguish any fire that may extend to the floor above. Section 4.3.1

A. Agree
B. Disagree

Answer 11

11. B
12. 3.1 Store fires in OLTs may involve a large amount of combustible material. A 2 ½” line should be stretched for large volume fires and a second line stretched to the entrance hallway. When assured that the second line is not needed on the first floor, it may be advanced to the floor above the fire.

Question 12

12. Portable ladders may be placed over weakened, damaged, or burnt out stairs in order to
    safely gain access to the upper floors of a building. Which ladder listed below is the preferred
    ladder to place over a burnt, damaged, or weakened stairway? Section 4.S.5

A. Straight Ladder
B. Extension Ladder
C .Scissor Ladder
D. “A” Frame Ladder

Answer 12

12. B

4.5.5 Portable ladders may be placed over weakened, damaged or burnt-out stairs in order to safely gain access to upper stories of a building. The preferred ladder for
this is the extension ladder, rather than a straight ladder. The shorter nested length allows easier maneuverability and positioning, while the adjustable length
should insure proper coverage of the entire stair span. The butts shall be supported by the floor at the base of the stair, while both upper beams at the tip of the ladder should rest on the upper floor landing for proper support.

Question 13

13. Lt. Strawberry is working a night tour in E-99 and has just arrived with his unit at a fire in an OLT. The fire is in apartment 2L on the second floor. The fire is blowing out the windows of a bedroom and into the shaft on the exposure 2 side of the building. There is a heavy fire condition in the shaft and the fire has also spread to the living room and kitchen in the apartment. Lt Strawberry would be correct to take which action listed below? Section 4.7

A. Order the 1st hose line stretched to the roof of the building and have the nozzle man operate
the line into the shaft to extinguish the fire in the shaft.

B. Order the 1st hose line stretched into the cellar since the fire in the shaft can bum down into the cellar.

C. Order the 1st’ hose line stretched to apartment 2F and extinguish the fire in the bedroom, living room, and kitchen and then direct the hose line to be operated into the shaft to extinguish the shaft fire.

D. Order the P’ hose line stretched to apartment 2F and extinguish the fire in the bedroom. After the bedroom fire is extinguished have the line operated into the shaft to extinguish the fire in the shaft. Then extinguish the living room and kitchen.

Answer 13

13. D
14. 7.6 For fires in rooms in the vicinity of a shaft, after the fire in the room has been knocked down, the line should be operated into the shaft in order to knock down the shaft fire before continuing through the apartment for knockdown and final extinguishment

Question 14

14. During BISP members of L-lOO were discussing Old Law Tenements. Which point made by the members of L-100 is correct? Section 4.8.1 A, 4.8.8,4.8.5 B
    A. Because of the short span of floor beams (25’), and the fact that the floors are heavily loaded, the collapse of floors in OLT’s is usually a problem.
    B. Rear tenements may be found behind OLT’s. These rear tenements are usually 25’ to 50’ behind the front building. Usually it is necessary to go through the front building to get to the rear building.
    C. Rear tenements are small in area and may be of frame or non- fireproof construction and may range from 2 to 5 stories in height.
    D. In some areas 2 or 3 adjacent OLT’s have been altered and interconnected to create one building with one street entrance. All the original avenues for fire spread common to OLT’s have been eliminated in these renovated buildings.

Answer 14

14. B

C. The distance between the front building and the rear building varies, but is somewhere between 10 to 25 feet usually.

Question 15

15. On some OLT’s party wall balconies will be found. In the event of a fire, the occupants would use the fire escape balcony to escape to an adjoining building. Which point below is incorrect regarding party wall balconies on OLT’s? Section 4.8.7
    A. The fire escape can be used to gain access to the roof since a gooseneck ladder will found on the top balcony.
    B. Firefighters cannot use the fire escape to go from one floor to another for ventilation and search purposes.
    C. The fire escape cannot be used for stretching hose lines.
    D. Party wall balconies connect two or more buildings.

Answer 15

15. A

The fire escape cannot be used to gain access to the roof.

Question 16

16. Which type of stairway listed below is considered to be a tremendous asset in heavy fire operations on the top floor of a New Law Tenement? Section 5.2.5
A. Transverse stairs
B. Wing stairs
C. Isolated stairs
D. Scissor stairs

Answer 16

16. A

Transverse stairs-these stairs are usually located at points remote from each other, but a person can go (transverse) from one stairway to another via the public hall on all floors of the building. Their layouts ease evacuation, assist in examination and permit lines to be stretched to any apartment, via any stairs. They are a tremendous asset in heavy fire operations on the top floor.

Question 17

17. The number and location of stairways do not adhere to a common pattern in New Law Tenements. Some stairways will be found near the front entrance while others will be some distance away. Which point below regarding stairways in New Law Tenements is incorrect?
    Section 5.2.5
    A. It is essential that once the stair layout is recognized in a NLT, this information must be relayed by handle talkie as this is vital in the size up picture.
    B. Transverse stairs are usually located at a point remote from each other, but a person can go (transverse) from one stairway to another via the public hall in the lobby of the building only.
    C. Wing stairs, one or two, are located at the front and rear of each wing. The floor landing leads to a public hall that will join the other stairs in that wing only (if two stairs). The public hall does not transverse to the other wing of the “H”.
    D. Isolated stairs are usually identified by their individual entrances. Access is limited to the apartments served by the stairs and there is no access to other wings so hoseline operations are confined to their limited area.

Answer 17

17. B
18. The number and location of stairways do not adhere to a common pattern in New Law
    Tenements. Some stairways will be found near the front entrance while others will be some
    distance away. Which point below regarding stairways in New Law Tenements is incorrect?
    Section 5.2.5
    A. It is essential that once the stair layout is recognized in a NLT, this information must be
    relayed by handle talkie as this is vital in the size up picture.
    B. Transverse stairs are usually located at a point remote from each other, but a person can go
    (transverse) from one stairway to another via the public hall in the lobby of the building only.
    C. Wing stairs, one or two, are located at the front and rear of each wing. The floor landing
    leads to a public hall that will join the other stairs in that wing only (if two stairs). The public
    hall does not transverse to the other wing of the “H”.
    D. Isolated stairs are usually identified by their individual entrances. Access is limited to the
    apartments served by the stairs and there is no access to other wings so hoseline operations are
    confined to their limited area.

Question 18

18. You are working a day tour in L-33 when you arrive at a fire in a 6 story new law tenement. The fire is on the 5th floor and is blowing out the windows in the throat, court yard, and the front of the building. The IC orders you to set up the tower ladder and to attack the fire using the tower ladder stream. You would be correct to take which action below?
    Section 5.4.2
    A. Order the stream operated into the front windows first and then knock down the remaining fire in any order.
    B. Order the stream operated into the front windows, then the windows in the court yard, and finally into the windows in the throat.
    C. Order the stream operated into the windows in the throat first, then the windows in the court yard, and finally into the windows in the front of the building.
    D. Order the stream operated into the windows in the court yard first, then the windows in the front of the
    building, and finally the windows in the throat of the building.

Answer 18

18. C

5.4.2 Aerial ladders, if first to arrive, should not be positioned so as to block off the front entrance courtyard. When possible, this position should be taken by a tower ladder. If rescue operations must be performed, the aerial shall, of course, be positioned to carry out this function. If the fire is showing out windows in the throat, courtyard
and front windows, and a tower ladder stream is being used, it should be directed at the windows in the throat first. The stream should then be advanced toward the
front of the building and finally operated into the front windows.

Question 19

19. When operating at fires in the newer large “H” shaped buildings with steel frame construction the probability of fire extension is greatly increased due to the many shafts, voids, and recesses that may be found. Which choice listed below is the most probable point for
    vertical fire extension? Section 5.2.6, 5.10.1
    A. Dumbwaiter shafts
    B. Vertical steel channels
    C. Closets, since their usually constructed above one another
    D. Pipe recesses

Answer 19

19. B

5.10.1 Checking for fire extension: When a heavy fire is encountered in one apartment,
all sides and above and below the fire area, must be examined. Nothing can be
taken for granted. The most probable point for vertical fire extension will be the
vertical steel channels (in buildings that have steel frame construction). These
columns have no specific location and many are completely hidden. Any boxed
out area is there for a purpose and, if involved in fire, must be opened up and
examined. Closets are another very probable point of vertical extension. At
times the vertical steel columns are located in the walls of these closets. Fires in
channel rails necessitate opening up above and at the top floor ceiling to check for
extension into the cockloft.

Question 20

20. Construction of “H” type buildings has remained basically the same for over 100 years. The exterior walls are masonry, and generally of brick. The floors, roof, and interior framing are partly or wholly of wood and columns and girders are unprotected steel. Which point below
    regarding top floor and roof construction in these “H” type buildings is correct? 5.2.4
    A. The cockloft is a large concealed void between the top floor ceiling and the underside of the roof boards. It is large enough to be considered an attic and will have at least one point of entry.
    B. The cockloft is required to be subdivided in some cases by fire stopping. This fire stopping will always restrict the spread of fire.
    C. The most common roof has the top floor ceiling several feet below the main roof beams.
    The roof boards are fastened directly to the top of the roof beams.
    D. The most common roof is an inverted, raised, or reversed roof. The main roof beams are at
    ceiling level and a frame work is raised above these beams with the roof boards attached.

Answer 20

20. C

B. The most common roof has the top floor ceiling several feet below the main roof beams. The roof boards are fastened directly to the top of the roof beams. This provides for a sturdy roof. In the inverted, raised or reversed roof, the main roof beams are at the ceiling level and a framework is raised above these beams with the roof boards attached. This roof is normally springy, but it permits the roof to be pitched so that water will run off. (Figure 11)
If there is a heavy body of fire in the cockloft, expect at least a partial collapse of the inverted roof. Since the inverted roof is constructed of 2 x 4’s, they will burn away faster than the main roof beams and the roof section will come to rest on these beams.

Question 21

21. E-99, E98, E-97, LI00, and LI01 are 10-84 and operating at a fire on the top floor of a 4 story NFP multiple dwelling. The fire started in and is now burning in the cockloft. Battalion 1 is stuck in traffic and Division 2 was involved in an accident on the way to the box. The 1st line
    has been stretched by E99 and E98 and is in operation. The officer of E97 orders his unit to put their cockloft nozzle into operation and tells the control firefighter to go to the Engine and get the cockloft nozzle. He told his members that the hose for the 2nd line will be used to operate the cockloft nozzle. Do you agree or disagree with the order from the Officer of E97?
    TB Tools 7, Data Sheet 18
    A. Agree or B. Disagree

Answer 21

21. B

2. 2 The cockloft nozzle is carried by all Squad Companies and Division vehicles.

Question 22

22. While Division 2 was visiting the quarters of E99 and LI00, members removed the cockloft nozzle from the Division vehicle and had an impromptu drill. Which point made about the cockloft nozzle was incorrect? TB Tools 7 Data Sheet 18
    A. The cockloft nozzle is designed to extinguish fires in the confined space of any building with a cockloft. The cockloft nozzle cannot be used at any other type of incident.
    B. A hole, approximately 3’ x 3’ is needed in the ceiling in order for the cockloft nozzle to fit. A minimum of 4” is needed between the top of the ceiling joists and the bottom of the roof Joists.
    C. When using the cockloft nozzle in a NFP Multiple Dwelling, the preferred location for operation is immediacy inside the apartment door as this will give members with a degree of protection provided by the public hallway.
    D. Do not rotate the cockloft nozzle in a continuous counter clockwise direction as this action may cause the nozzle to become unscrewed from the shut off. The use of the cockloft nozzle does not eliminate the need of pulling ceiling for final extinguishment and wash down.

Answer 22

22. A

2.1 The cockloft nozzle is designed to extinguish fires in the confined space of any building with a cockloft. The cockloft nozzle should NEVER be the primary attack line and is ONLY to be used when supported and protected by an additional conventional handline.
Note: The IC shall consider use of the cockloft nozzle at any incident where its unique
capabilities may be beneficial.

Question 23

23. While operating as the FAST truck at an all hands for a fire in a NFP Multiple Dwelling, you decide to explain to the proby how the FDNY identifies the various wings in these large buildings. The building you are operating at has 3 wings, each of which is connected by a throat.
    You would be correct to tell the proby? Section 5.6
    A. The 1st officer inside the building will let the IC know how the particular building designates its various sections. We will then be guided by the particular buildings designations.
    B. Standing in front of and facing the fire building and beginning on your extreme left, wings
    shall be designated A, B, C, D etc. The entire wing from front to back of the building shall be A, B. etc.
    C. Standing in front of and facing the fire building and beginning on your extreme left, wings shall be designated 1, 2,3,4 etc. The entire wing from front to back of the building shall be 1,2, etc.
    D. Standing in front of and facing the fire building and beginning on your extreme right, wings shall be designated 1, 2, 3, 4 etc. The entire wing from front to back of the building shall be 1,2, etc.

Answer 23

23. B

5.6.3 Standing in front of and facing the fire building and beginning on your extreme left, wings shall be designated A, B, C, D etc. The entire wing from the front to
the back of the building shall be A, B, etc. The wing shall be further subdivided by the term: front and rear or front, center and rear, if necessary. That part of the building connecting each wing shall be designated the throat and shall be referred to as the throat between A wing and B wing etc. (Figure 15) At an escalating fire it may be necessary to establish subordinate levels of command in the wings of the building. The same description of building wings can be used to describe the assignment i.e., Sector A, B, C, D or if necessary Branch A, B, C, D.

Question 24

24. Listed below are different dimensions of openings required or suggested at different operations. Which one listed below is the only correct one? (Taxpayers 5.5.16,Ladders 3 5.9.6, MD’s 5.9.9, PD’s 6.3 and 11.3, Ladders 6 TL Ops. 4.3)
    A. At a fire in a taxpayer cutting a 6’ x 6’ hole is recommended in providing ventilation at the roof.
    B. A coffin cut is approximately 4’ x 6’.
    C. When cutting a trench in the roof of an MD, the trench should be at least 4’ wide and about 20’ from the initial vent hole.
    D. To access a fire in the attic of a private dwelling from the floor below, a 3’ section of ceiling should be opened up

Answer 24

24. D
25. 5.16 Cutting a hole eight feet by eight feet is recommended in providing ventilation at the roof. In a serious fire, instability, heat, or smoke conditions may make the cutting of this primary vent hole impossible, delaying overall effective ventilation.
26. 9.6 Sequence - The size and location of the opening will depend on fire conditions. A suggested method to make an expandable opening “COFFIN CUT” is as follows: A. Assume wind is blowing in direction indicated. (Ideally at your back) B. Cut #1 approximately 3 feet. C. Cut #2 “knock out” corner cut for tool insertion. D. Cut #3 approximately 6 feet. E. Cut #4 to #7 approximately 3 feet. F. Leave removed pieces of roof section next to opening to warn operating forces. G. If larger opening is needed, additional opening can be made in like manner. (Continuation of cut in desired direction) H. Make sure that roof is not opened before cut is completed. I. Push down ceiling to complete ventilation.

C. To be effective, the trench must be properly located, at least 3’ wide, and cut from wall to wall or other suitable fire stop, such as a stair or elevator bulkhead. Failure to complete a trench may allow a fire to pass to the other side of the trench.

Question 25

25. Lt. Carter is operating at a fire in the cockloft of a 1 story taxpayer. Lt. Carter has been assigned as the roof sector supervisor and decides to have members operating on the roof start a trench cut. Lt. Carter immediately notifies the IC that a trench cut has been started. Do you agree or disagree with Lt. Carter’s actions? Taxpayers 5.6.4
    A. Agree or B. Disagree

Answer 25

25. A
26. 6.4 The Roof Sector Supervisor can start a trench cut where he/she sees the necessity for it. Immediate notification to the Incident Commander of the operation is mandatory.

Question 26

26. One of the techniques used to stop the spread of fire in a cock loft is to cut one or more trenches in the roof. Which point made during drill about trench operations is incorrect? 5.9.9
    A. Trenching is an offensive operation performed to limit the extension of fire in the cock loft. A trench should be cut and pulled immediately after there is a vent opening directly over the fire.
    B. To be effective a trench must be properly located, at least 3’ wide and cut from wall to wall or other suitable fire stop such as a stair or elevator bulkhead.
    C. A charged line should be in position on the roof to protect personnel and the trench opening. This line may be operated into the trench in a brief, sweeping, side to side motion to prevent fire from extending across the opening.
    D. Personnel cutting a trench or a ventilation hole on a roof must be assured a way of getting off the roof. Keep all personnel off the roof on the fire side of the trench.

Answer 26

26. A

B. Trenching a roof is a defensive operation that is performed to limit the extension of fire in the cockloft. A trench may be cut, but should not be opened, until there is an adequate vent opening directly over the fire. Ideally, the trench should be precut, but not pulled. Two or more inspection holes may be cut on the fire side of the trench. When, and if, the fire reaches the inspection holes, the precut trench is pulled. This sequence lessens the possibility of the fire moving rapidly and prematurely towards what is, in effect, a second distant opening (the trench) cut in the roof.

Question 27

27. FF Smith made the following three statements:

1 Know the floor, wing, section, side or exposure where you are operating. It is essential that all members at the scene use the same terminology. A fire escape in the throat often spans the firewall and indicates two (2) separate apartments in the throat.

2 One apartment in the throat may span a firewall with no fire escape and have two interior exits, one to the stairway in one wing and the other to the adjacent wing. Both doors are usually openable and not obstructed by furniture. A search of this apartment must be thorough.

3 The  law  requires  the  subdivision  of  these  large  NFP  Multiple  Dwellings  into  smaller  areas. However,  there  is  no  way  to  determine  the  location  of  these  subdividing  walls  from  the outside  of  the  building,  except  in  these  few  cases  where  they  are  continued  above  the  roof. Which  statements  are  correct?
A.  2  and  3
B.  1  and  2
C.  I  and  3
D.  All  are  correct

Answer 27

27. C

Question 28

28.  Units  are  operating  at  a  fire  in  a  14  story  hi-rise  fireproof  multiple  dwelling  (HRFPMD). The  fire  is  on  the  7th  floor  in  apartment  7A.  Which  unit  listed  below  is  responsible  to  ensure  the elevators  are  recalled  and  searched  at  this  fire.  6.4.1 
A.  The  1st  arriving  ladder  co.
B.  The  2nd  arriving  ladder  co.
C.  The  FAST  truck.
D.  The  4th  arriving  ladder  co.

Answer 28

28. B
29. 4.2 Stairs shall be used when the fire is on the seventh floor or below. The first arriving ladder company shall recall the elevators, whether or not they will be used. The second to arrive ladder company shall ensure that all elevators are recalled and searched. Regardless of the fire floor, the IC must ensure that all elevators are recalled, searched and controlled early in the operation, preventing civilians from placing themselves in danger by entering the elevator cars during the incident.

Question 29

29. E-99 and L-100 have just arrived at a report of a fire on the 14”’ floor of a 26 story HRFPMD. Upon arrival in the lobby the officer of E-99 sees that there are 2 elevators, however one of them is out of service. The remaining in service elevator is equipped with fireman service and only serves the odd floors. Outside operations are not possible since the building is located in the middle of a cluster of other buildings. Which action listed below would be correct for members of E-99 and L-100 to take at this operation? Section 6.4
    A. The Ladder Co. Officer, Irons, Can, OV, Engine Officer, and the Nozzle firefighter should use the elevator and take the elevator to the 11”’ floor.
    B. The Ladder Co. Officer, Irons, Can, OV, Engine Officer, Nozzle, and Control Firefighter should use the elevator and take the elevator to the 11”* floor.
    C. The Ladder Co. Officer, Irons, Can, OV, Engine Officer, Nozzle, and Control Firefighter should use the elevator and take the elevator to the 12”’ floor.
    D. The Ladder Co. Officer, Irons, Can, OV, Engine Officer, and Control firefighter should use the elevator and take the elevator to the 13”* floor.

Answer 29

29. A
30. 4.5 Overloading of elevators must be avoided or the units responding will be delayed arriving at the fire/emergency floor. A stalled elevator car is an elevator car out of service. Look for maximum load signs and consider each member and their equipment to be greater than 275 pounds.
31. 4.6 When both the engine and ladder companies arrive together and only one elevator is available (non fireman service), the ladder officer with the forcible entry team and the engine officer with two firefighters (nozzle & control) with all rolled up lengths and standpipe kit shall go up first. If the elevator has Firemen Service, and no outside operations are indicated, the OV will be operating the elevator. This will necessitate reducing the elevator load by one of the engine firefighters. Remaining members in the lobby are to make up a second team for the next elevator or consider using the stairs. This approach will allow these members to begin setting up equipment for the appropriate attack strategy and size-up information to be conveyed to the IC and all other operating units.

Question 30

30. Which choice below correctly shows where elevators should be located after all units are in position when operating at a fire on the 23’” floor of a 45 story HRFDMD and two elevators area available and serviceable? 6.4.8
    A. One elevator in the lobby and one elevator at the location of the Fire Sector Supervisor.
    B. Both elevators at the location of the Fire Sector Supervisor.
    C. Both elevators in the lobby.
    D. One elevator in the lobby and one elevator 1 floor below the location of the fire sector supervisor.

Answer 30

30. D
31. 4.8 After all units are in position, and two elevators are available and serviceable, maintain one elevator on standby in the lobby and one two floors below the fire. This would allow the transport of members required for relief and/or transport of injured members or civilians down to the lobby.

Question 31

31. Premature ventilation in HRFPMDs can cause negative consequences for our operating forces. Which one of the four most prominent variables that affect smoke movement is correctly described? 6.2.2
    A. Wind - creates high pressure on the leeward side.
    B. Pressure - high air pressure will sometimes travel to areas of low air pressure.
    C. HVAC - An IC should confirm all HVAC’s are shut down after commencing any fire operations.
    D. Stack Effect - Can be either up or down and is most often in the direction of the vertical shafts.

Answer 31

31 D

6.2.2 The most prominent variables that affect smoke movement are:
 Pressure: Smoke and hot fire gases increase the air pressure inside the fire area or fire apartment. This higher air pressure will always travel toward areas of lower air pressure, creating a flow path for the fire to travel. These
lower air pressure areas are the public hallways, vertical shafts, stairwells and elevators. Lower air pressure areas also include other open apartment doors and open windows, especially on the opposite side of the public hallway from the fire apartment. Vertical ventilation will only be performed at the direction of the IC. This must be coordinated through direct communication with the
engine and ladder company officers operating in the fire sector or the Fire Sector Supervisor.

 Stack Effect: Natural, thermal air movement, either positive (up) or negative (down) within a structure, most often in the direction of vertical shafts. The stack effect is influenced by the height of the building, temperature
differential between outside and inside temperatures, air leakage to other floors, and the wind.

 Wind: A major factor for smoke movement within a structure. Wind pressures external to the building create pressures within the structure on both the windward side (high pressure) and leeward side (low pressure) because of leakage through windows, walls or other openings, however small. The degree of increased internal pressure depends upon the extent of leakage. Wind blowing into a fire apartment before extinguishment will accelerate the
fire into blow torch proportions, pushing fire and heat to lower pressure areas throughout the fire floor and building. Wind blowing into an apartment after
a fire is controlled will push smoke to lower pressure areas throughout the building. Wind blowing across the roof level is also a factor to consider. If it is blowing into an open, roof bulkhead door, it will cause heat and smoke to
flow downward, causing the lower floors and/or lobbies to be contaminated with smoke during fire operations. Generally, wind moving across a roof level will cause a lower pressure to be created, which can increase positive
stack effect inside the stairwell, regardless of which side of the building the wind is impacting or the position of the bulkhead on the roof. The Department has always been aware of the dangers and problems associated with wind impacted fires on any floor of a fireproof multiple dwelling. When the fire apartment door has been left in the open position and the windows fail, the public hall becomes an extension of the fire area. We must always consider the effects of wind at every fire encountered. Improper ventilation, even when the fire is on a lower floor, or appears to be minor, can have disastrous results

HVAC: These systems and their components of duct work and shafts can contribute to smoke infiltration in other areas of the building. An IC should confirm that all HVAC systems are shut down prior to commencing any fire
operations. They are installed most commonly in hotels and the hallways of up scale high-rise apartment buildings.

Question 32

32. During multi-unit drill, members were discussing a recent fire that occurred on the 45”* floor of a 60 story HRFPMD. The conversation included where certain units were positioned, their actions, and the tools they carried. Which unit did not operate in accordance with FDNY
    SOP’s? 6.6.3,6.11,6.12,6.19
    A. E-99 was assigned as the CFRD Engine. Upon their arrival, E-99 reported in to the IC and was assigned to the Fire Sector. E-99 went to the 44”’ floor with their CFRD equipment and forcible entry tools. E-99 announced their designation as the CFRD Engine, ascertained the
    identity of the FAST unit, and monitored handie talkie transmissions while standing fast.
    B. L-lOO was assigned the ventilation support group at this fire. Upon arrival L-lOO immediately took one PPV fans from their 2”” piece in order to pressurize the evacuation stairway.
    C. E-98 was assigned as the 5”’ due Engine and since E-98 was not equipped with a High Rise Nozzle (HRN) the officer contacted the dispatcher to find out which unit assigned on the 10-77 was equipped with the HRN. Upon arrival the officer had his members bring the HRN (from E-
    99), one length of hose per firefighter, and the standpipe kit into the lobby. E-98 reported into the IC and was told by the IC to stand fast in the lobby.

Answer 32

32. B
33. 6.3 The FAST Unit and CFR Engine shall be assigned to the Fire Sector when the fire is above the sixth floor. They can be staged on the floor below the fire floor, ready for rapid deployment. At lower floor fires (sixth floor or below), the position of the FAST Unit and the CFR Engine will be determined by the Incident Commander. The FAST Unit should carry a set of elevator keys.

6.11 5TH ENGINE COMPANY TO ARRIVE
The 5th assigned engine company is responsible for placing the High Rise Nozzle (HRN) into operation, if this alternate strategy is needed. If the 5th assigned engine company is not equipped with a HRN, the officer shall contact the dispatcher for the identity of the unit carrying the HRN that has already been assigned to the 10-77.

Note: Every 10-77 will have at least one HRN equipped engine company assigned to the incident. Each Battalion has at least one engine company that is equipped with a HRN.

6.11.1 Equipment:
 One length of hose per firefighter
 Standpipe kit
 High Rise Nozzle

6.11.2 Duties:
Upon arrival, the 5th Engine Officer will have his/her unit bring the HRN, one length of hose per Firefighter and the standpipe kit, and report in to the IC at ICP. Upon the IC’s orders, bring all their equipment to the floor below the fire. They be prepared to support the following:
 If the HRN is to be used, the 5th assigned engine will put it into operation. They will either use the hose already in place for the second hoseline, or stretch their own line. Notify the IC or Fire Sector Supervisor for assistance if
needed with the hose stretch or forcible entry.

6.12 CFR ENGINE COMPANY
This unit will report to the Incident Commander and stand by with the FAST Unit.
6.12.1 Equipment:
 CFR equipment
 Forcible Entry Tools
6.12.2 Duties:
 Announce designation as CFR Engine and ascertain identity of FAST Unit.
 Monitor handie-talkie transmissions while standing fast.
 Note the designation of attack, evacuation stairways and apartment numbering
system, etc.

6.19 VENTILATION SUPPORT GROUP
The Ventilation Support Group will be the 6th ladder company assigned on a 10-77. They will arrive with their second piece of apparatus and report to the IC with two positive pressure ventilation fans. Their assignment is to pressurize the ATTACK AND EVACUATION stairs in HRFPMDs in order to keep heat and smoke from entering the stairwell. Stairwell pressurization will not be initiated until authorized by the Incident Commander.

6.19.2 Duties:
A. The attack stairwell is the first consideration for pressurization and will be pressurized upon the order of the IC.

Question 33

33. During MUD in Manhattan, units were discussing ventilation procedures employed duringfires in HRFPMD’s. Ventilation procedures in HRFPMD’s vary greatly from the procedures we use for non-fire proof multiple dwellings. Which point listed below is incorrect? 6.3,6.5
    A. It is not usually necessary to force apartment doors on the fire floor other than the fire apartment door. When the main body of fire has been controlled, adjoining apartments can beforced for reasons such as high carbon monoxide readings or severe smoke conditions in thepublic hallway.
    B. Horizontal ventilation of the fire apartment is limited and controlled by the ladder officeroperating inside the apartment. All other ventilation must be strictly limited and controlled by the IC.
    C. If it is decided that an apartment door is going to be forced to provide an area of refuge, the door selected must be to an apartment that is entirely on the opposite side of the building as thefire apartment.
    D. In some HRFPMDs, there may be windows in the public hallways and stairways. Hallwayand stairway windows make the task of controlling flow paths more difficult. These windowsshall not be ventilated without prior approval of the IC.

Answer 33

33. C

If it is decided that an apartment door is going to be forced to provide an
area of refuge, the door selected must be to an apartment that is entirely on
the same side of the building as the fire apartment. This will prevent fire
from being drawn across the hall if the fire apartment windows fail,
putting members in the flow path.

Question 34

34. Variations from stretching initial hose lines from standpipe outlets on a floor below the firedue to building configurations shall be approved by and entered into the CIDSprogram. The Engine Company to arrive must ensure the standpipe Siamese is suppliedand provide assistance where necessary. 6.7.1,6.8.2
A. Battalion Commanders / 3rd
B. Battalion Commanders / 2nd
C. Division Commanders / 2nd
D. Borough Commanders / 4th

Answer 34

34. C

Variations from stretching initial hoselines from standpipe outlets on a floor below the fire due to building configurations shall be approved by Division Commanders and entered into the CIDS program.

6.8.2 Duties: Upon arrival, ensure the Siamese is supplied and provide assistance where necessary (e.g., extremely long stretch to the Siamese, broken Siamese, frozen hydrant, etc.)

Question 35

35. Lt. Sterling is working in E-lOO and has just returned to quarters after operating as the 1st due Engine at a 10-77. The fire was on the 12th floor of a 14 story HRFPMD. Lt. Sterling should reread the bulletin because his only correct action at this fire can be found in which choice below? 6.7.2

A. After communicating with the Ladder Co. Officer, Lt. Sterling chose the “A” stairway as the attack stair because this stairway had the standpipe. Lt. Sterling told the new officer from L-99 that the attack stairway must be the stairway with the standpipe outlet.
B. Lt. Sterling told his members that the hoseline must be charged before the line is advancedinto the public hallway because if window failure occurs and a wind impacted fire develops the hoseline will provide sufficient cooling of the hallway to protect exposed members.
C. Lt. Sterling ordered the OV from L-99, who was operating the elevator, to take himself and his members to the 11th floor. Upon arrival on the 11”* floor Lt. Sterling examined the hallway layout and checked to see if the scissor stairs were correctly labeled.
D. After the fire was extinguished Lt. Sterling called for the fog tip to be brought up to the firefloor since the positive pressure fans being used for smoke removal and stairwell pressurization were ineffective in venting the fire apartment. The fog stream was directed out an open window from the fire apartment.

Answer 35

35. D

7.2 Duties: Take elevators to at least two floors below the reported fire floor using precautions normally taken with elevators. Examine this floor for the following:  Hallway layout;  Scissor stairs correctly labeled;  Location of the reported fire apartment;  The best stairs from which to attack the fire;  Length of stretch from the attack stairs to the fire apartment;
 The number of apartment doors from the attack stairs to the fire apartment door;  All turns the hose stretch will need to make in order to reach the fire apartment. Communicate with the ladder company officer to select the attack stairway. The attack stairway need not be the stairway with a standpipe outlet. The hoseline can be connected and stretched on the floor below and then up another stairway that is closer to the fire apartment to facilitate advance. Take time to make a reasonable choice. Due to conditions caused by a wind impacted fire, one stairway may afford an advance with conditions less severe. Once the attack stairway is selected, all hoselines will be stretched and operated from this stairway. Notify the 2nd engine and IC of the designation of the attack stairway.

Question 36

36. It has become common for the New York City Housing Authority to have apartment letters stenciled on the exterior of the building, either on or below the first floor window sill. These markings provide a valuable reference point and should be included in the OV’s size up. L-26 is on BISP in their administrative area when they notice that the buildings they are inspecting in a NYCHA complex do not have the apartment letters stenciled on the exterior of the building.L-26 should take which action listed below? 6.14.3
    A. Forward a DOB Referral to the Dept. of Buildings.
    B. Notify the BISP unit.
    C. Forward an A8 to BFP marked city agency.
    D. Contact the local management office and request that they be provided

Answer 36

36. D

Note: It has become common for NYC Housing Authority to have apartment letters stenciled on the exterior of the building; either on or below the first floor window sill. These markings provide a valuable reference point and should be included in the OV size-up. Be aware that in some instances, the actual apartment lettering can change from floor to floor and not all apartments will line up in the same vertical row. This condition is usually found between the first and second floors, but may vary between upper floors as well, especially in buildings with duplex and sandwich apartments. It is crucial that only correct apartment information be conveyed to units operating within the building. Therefore, when giving a report from the exterior of the building, the OV should include the letter markings as a guide; e.g., “L26 OV to L26, on the exposure 3 side I see light smoke seeping from an 8th floor window. That should be the “B” apartment according to the exterior markings.” Units with NYC Housing complexes in their administrative district that do not have the markings, or where markings have faded, can contact the local management office and request they be provided or updated

Question 37

37. Lt. Carter is working in L-lOO and has just arrived with his members at a report of a fire on the 7”’ floor of a 9 story HRFPMD. Lt. Carter was met by the occupants in the lobby and they told him that the fire is in their apartment, apt 7A, and that they can’t remember if they closed the door when they ran out of the apartment. After consulting with E-97, the “A” stair was chosen as the attack stairway. Lt. Carter and his members then used the “A” stairway to get to the 7’*’ floor and were unable to determine if this was a wind impacted fire. In this situation Lt.Carter would be correct to take which action listed below? 6.14.2 D

A. Lt Carter should enter the public hallway to locate the fire apartment and control the fire apartment door while the irons and can firefighters remain inside the stairwell.
B. Lt. Carter and his Irons firefighter should enter the public hallway to locate the fire apartment and control the fire apartment door. The Can firefighter should remain at the attack stairway door on the hallway side of the door.
C. Lt. Carter and his Can firefighter should enter the public hallway to locate the fire apartment and control the fire apartment door. The Irons firefighter should remain at the attack stairway door on the stairwell side of the door.
D. Lt. Carter and his forcible entry team should enter the public hallway to locate the fire apartment and control the fire apartment door.

Answer 37

37. B

If unable to determine if this is a wind impacted fire, the Ladder Company Officer and one member of the forcible entry team shall enter the public hallway to locate the fire apartment and control the fire apartment door. The other member of the interior team will remain at the attack stairwell door on the hallway side of the door to ensure the stairwell door remains closed limiting the flow path and to act as a beacon in case members need to evacuate the hallway. The Engine Company Officer shall be responsible for control and coordination on the stairwell side of the door.

Question 38

38. Probationary firefighter Duda was working a 9x6 tour and was assigned the roof position for the 1st time in his career. After operating as the 1st due truck at a fire in a HRFPMD, FF Duda and his Captain reviewed his actions at this fire. The Captain should correct FF Duda as she was mistaken in which action he took at this fire? 6.14.4
    A. FF Duda carried the halligan tool, hydra ram, and the KO curtain and proceeded to the apartment directly over the fire via the attack stairway.
    B. FF Duda notified the Captain of the apartment layout and the fire location on the fire floor after seeing fire coming from the living room windows of the fire apartment.
    C. FF Duda kept the apartment door on the floor above open and then opened a window in the room over the fire room to simulate how the wind will flow through the fire apartment.
    D. Upon orders from the IC to deploy the KO curtain, FF Duda broke the living room window and then deployed the KO curtain from the floor above the fire. Since there was some minor auto exposure FF Duda called for a can.

Answer 38

38. D

KO Curtain deployment may be needed. Fire pulsating from a window indicates gusting wind conditions or over pressurization of the fire room by the wind, and may at first allow fire to vent out of the window, only to push the fire back into the window without warning. Do not break the window glass. Open window; deploy WCD when ordered by the IC, then close window onto the WCD ropes. Auto exposure is possible. Call for an extinguisher or hoseline if needed.

Question 39

39. At a 10-77 where all 6 assigned ladder companies are on the scene, the roof firefighters from and to arrive ladder companies will bring the KO curtain to the apartment directly above the fire apartment. Which ladder company is responsible to confirm that the evacuation stairway door(s) have been closed on the fire floor and are maintained in the closed position? Which ladder company is responsible to initiate a search of the attack stairway for 5 floors above the fire to search for any building occupants that may have tried to evacuate using these stairs?6.14.4.6.16.4.6.16.2, 6.15.2 H

A. 1st & 3rd/ 3rd/2nd
B. 2nd & 3rd/ 2nd/ 4th
C. 1st & 2nd/ 1st/ 3rd
D. 1st & 3rd/ 1st/ 2nd

Answer 39

39. A

!st Ladder
6.14.4 Roof Firefighter Tools: Halligan, Hydra Ram, and KO Curtain

3rd ladder
6.16.4 The Roof Firefighter shall proceed to the apartment directly above the fire with a KO Curtain, in addition to his/her normal complement of tools, to assist members operating on that floor.

6.16.2 The 3rd ladder company officer shall confirm the evacuation stairway door(s) have been closed on the fire floor and are maintained in a closed position. This may be accomplished by positioning members on the stairwell side of the evacuation stairway door(s) until the Fire Sector Supervisor and/or the IC deems that the situation no longer presents a hazard in that particular stairwell. There may be more than one evacuation stairway in a building. Any stairway not designated as the attack stairway is considered an evacuation stairway.

2nd Ladder
6.15.2 H. After searching the hallway on the fire floor, initiate search of the attack stairway for five floors above the fire to search for any building occupants that may have tried to evacuate using these stairs. Communicate results of searches to the IC, or Fire Sector if established.

Question 40

40. During a class at ECC School, the Lieutenant teaching the class made the following points
    about standpipes and sprinklers found in high rise fire proof multiple dwellings. In which point
    was she mistaken? 6.27
    A. The ECC of the 1®’ to arrive Engine Co. shall connect a 3 1/2”line to the standpipe Siamese and charge the system if any evidence of fire is present. A second 3 1/2” line shall be stretched to supply the Siamese if more than one line is to be used from the standpipe.
    B. The sprinkler Siamese should be supplied when the building has a sprinkler system. Buildings with sprinkler systems should be entered into the CIDS system.
    C. Lightweight standpipe hose with 2” lead length and 1” MST shall be used as the 1st choice when operating from standpipes. If lightweight is not available then 2 1/2” hose with controlling nozzle and 1 1/8”’. MST shall be used.
    D. Some indications that no or insufficient water is being supplied to a standpipe system are flow meters registering no flow or low flow, heating of water in the apparatus pumps, and no change in pump pressure when the discharge gate is closed.

Answer 40

40. B
41. 27.6 Sprinkler siamese should be supplied when sprinklers are located in THE FIRE AREA OR ADJACENT AREA. Buildings with sprinkler systems should be entered on CIDS.

Question 41

41. E-99 has just arrived at a CFRD run in a 15 story HRFPMD, the caller is in apartment 2C. As members enter the building they are told by the security guard that there is only one public hallway every three floors and that the apartment doors are in groups of three in each public hall. When the occupant of 2C opens the door members have to walk down a flight of stairs to get to the apartment. After EMS took over patient care the members of E-99 knocked on the doors of apartments 2A and 2B. When the occupant of apartment 2B opened the door members noticed
    that the apartment was on the same level as the 2nd floor. When the occupant of apartment 2A
    opened the door she told the members that her apartment was upstairs. The rooms in each
    apartment were only on one level. These apartments are known as? 6.28.1
    A. Duplex type apartments
    B. Triplex type apartments
    C. Sandwich type apartments
    D. Tri-level type apartments

Answer 41

41. C

A third design type, while not strictly duplex or triplex apartments, but with similar problems for firefighters, is one where apartment entrance doors are in groups of threes in a public hall and there is only one
public hall every three floors. This is called the “sandwich” type apartment arrangement. When the apartment doors are in groups of three, you will find one apartment entrance door opens to an interior
stair leading down one flight to an apartment on the floor below. The next apartment door on the public hall leads directly into the apartment on that same level. The third door opens to an interior stairway leading up one flight to an apartment on the floor level above. The rooms in each apartment are on only one level, but as can be seen, if
the fire is in the lower level apartment, the firefighting techniques will have to be the same as for cellar fires.

Question 42

42. The New York City Housing Authority (NYCHA) has installed electromagnetic locking devices on the main lobby entrance doors to their buildings throughout the city. When the key FOB is placed near the reader located on the door frame, an audible tone is heard indicating that the door is unlocked. Which point listed below regarding the key FOBs and elevator machinery
    room keys is correct? MD’s Addendum 4
    A. When an FDNY unit receives a key FOB from NYCHA, the officer on duty shall record the serial number in the company journal. The key FOB shall be labeled and secured to the company officers radio (H/T).
    B. If the key FOB is lost or damaged the officer on duty shall notify the dispatcher who will notify NYCHA. The officer must relay the key FOB serial number to the dispatcher so that NYCHA can deactivate the key FOB.
    C. NYCHA has also issued elevator machinery room keys to all units. These keys are standard issue and do not have a serial number. If the key is lost the officer on duty shall call the NYCHA 24 hour emergency number to obtain a new key.
    D. Key FOB’s are specific to a particular housing authority complex. Key FOB’s issued to units may not work in other areas of the city.

Answer 42

42. C
43. 3 To provide easy access and reduce unnecessary damage to NYCHA building entry doors, key FOBs have been issued to all FDNY units. These key FOBs will grant universal access to all NYCHA buildings. Should the key FOB fail to unlock the door, it can be unlocked remotely by NYCHA Security. This can be done by calling the 24 hour NYCHA Emergency number at 212-306-8800, either directly or through the dispatcher. Units can also seek assistance from the building management office at the premise location.

Question 45

45. Which description of the different types of low rise fire proof multiple dwellings is not correct? 7.4
    A. Attached buildings with one stairway are attached to a similar building but separated by a fireproof wall. They usually contain one stairway from the first floor to the roof. Often this single stairway opens onto small public hallways.
    B. Individual buildings with two separate sections and fire doors are built as two separate sections, each containing two open stairways. These sections are separated by fireproof walls.
    C. Isolated Buildings with two stairways will not have an adjoining building and usually contain two enclosed stairways. The enclosed stairs are found remote from each other and roof access is generally via the enclosed evacuation stairway.
    D. Isolated buildings with only one stairway create a special situation when the roof cannot be accessed via an aerial or tower ladder. In buildings with a single interior stair, all attack and evacuation tactics will proceed from the one stairway, as there will not be separate designated attack and evacuation stairways.

Answer 45

45. B

7.5.2 Individual Buildings with two separate sections and fire doors
Buildings built with two separate sections, each containing a single open stairway. These sections are separated by fire doors. Roof access is generally via the interior stairway of the adjoining section, provided that the fire doors are in the closed position.

Question 46

46. Members of Ladder Co. 99 were discussing tactics when fighting fires in LRFPMD’s. Listed below are four different fires that L-99 recently operated at. At all of the fires they, L-99, were the 1” to arrive Ladder Co. In which fire listed below were they mistaken in their operations? 7.7.2 A, D, E, 7.7.3 B, Note
    A. Fire #1 - While conducting an outside survey the OV/LCC team split and each member surveyed the building from opposite directions. When no outside operations were possible the OV/LCC proceeded to the fire floor to assist in searches.
    B. Fire #2 - When the Officer of L-99 was notified by the IC that the 2nd to arrive Ladder Co.was delayed and not yet on the scene, he ordered the OV/LCC team to the apartment directly above the fire.
    C. Fire #3 - At this fire the building was an isolated building with two enclosed stairways.The roof firefighter used the enclosed evacuation stairway to get to the roof. The roof firefighter did not vent the attack stair bulkhead until ordered by the IC.
    D. Fire #4 - At this fire the building was an isolated building with one open interior stairway.The stairway was an IDLH and roof access via Aerial or TL was not possible. The Officer of L-99 determined that roof ventilation was needed so roof firefighter proceeded to the roof alone via the interior stairway.

Answer 46

46. D

Note: At isolated buildings where there is only one interior stair and no adjoining building, the Chauffeur will have to provide access to the roof for the Roof Firefighter. In this situation, the OV may initiate the appropriate OV/Chauffeur team tactics until joined by the Chauffeur.

Question 49

49. When fighting fires in FPMD’s size-up begins by observing the wind and weather conditions before the tour starts and knowing forecasted weather changes that will involve wind conditions. This information must be discussed at each roll call. Members must maintain
    constant situational awareness and accurately size-up conditions when responding to any reported fire in a FPMD. Which point below about size up is incorrect? 3.2,3.3
    A. The direction and speed of the wind at the street level is usually a reliable indicator of the wind conditions above the street level.
    B. It does not take high winds to dramatically increase fire conditions inside a building. When the wind subsides or shifts, pressure will equalize allowing the fire and smoke to vent out the J window.
    C. Fire or smoke visible inside the fire apartment that is not venting out of an open or failed window is a potentially dangerous, life threatening condition. This is the classic ventilation profile of a wind impacted fire.
    D. Prior to advancing to the reported fire floor, members must gather information by surveying the floor below or two floors below if scissor stairs are present.

Answer 49

49. A

 The direction and speed at the street level is not a reliable indicator of wind conditions above the street level.

Question 50

50. Units are operating at a fire on the 12th floor of a 14 story HRFPMD. It is a wind impacted fire and the KG curtain has been successfully deployed. The IC just notified the Ladder Co. Officer that he and his forcible entry team can enter the public hallway to locate the fire apartment and control the door. The Ladder Co. Officer and his irons firefighter enter the public hallway and quickly locate and control the fire apartment door while the can firefighter stayed at the attack stairwell door on the hallway side. The Ladder Co. Officer notified the Engine Co. Officer (who remained at the attack stairwell door on the stairway side of the door) that the fire apartment door is controlled. The Engine Officer ordered his members to stretch the charged line to the fire apartment door. The can firefighter also advanced to the fire apartment door. Once all members were in positron at the fire apartment door the Ladder Co. Officer notified the IC that conditions had improved and members were ready to enter the fire apartment. The IC approved entry into the fire apartment and the Engine Co. entered the fire apartment followed by
    the Ladder Co. Prior to the Engine entering the fire apartment the Engine Officer contacted the roof firefighter operating in the apartment above the fire and asked about the location of the fire and for a description of the fire apartment. Once the line was advancing towards the interior fire area, the door to the fire apartment was chocked open. Do you agree or disagree with the actions
    of these officers at this fire?
    Wind Impacted Fires 5.1
    A. Agree or B. Disagree

Answer 50

50. A

Question 51

51. A flanking strategy is the application of water from inside the fire building to control the main body of fire via a non-frontal attack. Lt. Kay was holding a drill in the kitchen after lunch regarding this tactic and made the following four points. He was only correct in which point?
    Wind Impacted Fires 4.2.4
    A. A small opening should be made in the adjoining wall to the fire room as close to an interior wall as possible.
    B. Initially, the hole in the adjoining wall should be about 3”. This size opening will allow the stream to be directed at the ceiling area.
    C. If the door to the fire apartment has been left open, the hoseline that is stretched to the adjoining apartment will be stretched via the public hallway on the fire floor into the adjoining apartment.
    D. If the door to the fire apartment is closed, the hoseline that is stretched to the adjoining apartment will be stretched via the public hallway on the fire floor into the adjoining apartment.

Answer 51

51. D

4.2.4 A Flanking strategy is the application of water from inside the fire building to
control the main body of fire via a non-frontal attack. A small opening is made in the adjoining wall to the fire room as close to the exterior wall as possible, so as
not to create a flow path. The hoseline is operated into the opening to extinguish
the fire. Initially, the hole in the wall should be only large enough for the main
stream tip of the nozzle to be placed into the opening allowing the stream to be
directed at the ceiling of the fire room.
A. Flanking attack when the door to the fire apartment has been left open:
 This option is available based on the location of the fire apartment, the location of a stairway closer to the selected apartment, and the interior hallway conditions.
 Enter an adjoining apartment to apply the hose stream to the fire room or fire apartment via a breached wall adjacent to the fire area, if this adjoining area can be accessed and occupied safely.
 Once access is obtained to the adjoining apartment, the door to that apartment must remain closed and the hoseline stretched to this adjoining apartment from the apartment below via an exterior window
or balcony using a utility rope.
B. Flanking attack when the door to the fire apartment is closed:
 Enter an adjoining apartment to apply the hose stream to the fire room or fire
apartment via a breached wall adjacent to the fire area, if this adjoining area
can be accessed and occupied safely.
 Once access is obtained to the adjoining apartment the hoseline will be
stretched via the fire floor public hallway into the adjoining apartment to
operate into the fire apartment.

Curtain is designed and shall be deployed ONLY in the vertical position.

5. 5 Open the Deployment Window without removing/breaking the glass, and remove any child guards or window gates. Do not remove the glass unless absolutely necessary. This window will need to be closed if auto-exposure becomes a problem.
6. 3 When a replacement of a Fire Window Blanket is required the company officer shall contact the Technical Services Division during normal business hours and request a replacement with an available spare.

Question 57

57. Lt. Smith was holding a drill and talking about the high rise nozzle. He made the following four points about the nozzle and was incorrect in which one?
    A. Putting the nozzle into operation will require the services of two engine companies equipped with roll-ups, standpipe kits, forcible entry tools including a rabbit tool and the high
    rise nozzle.
    B. A shut-off shall be placed in line two lengths back from the nozzle. When re positioning of the High Rise Nozzle is required, the supply line should be shut down at the shut-off located two lengths back and the nozzle opened to bleed the line.
    C. Once in position, the officer supervising nozzle operations will order water started. This officer will then notify the IC that the nozzle is in position and ready to operate. The nozzle will not be operated until the IC has given approval.
    D. The key to the rapid extinguishment of a wind-driven fire is putting water directly on the seat of the fire. If multiple rooms are involved, it will be necessary to re-position the nozzle to ensure complete knockdown of the fire.

Answer 57

57. B
58. 14 A shut-off shall be placed in line one length back from the nozzle. When re-positioning of the High Rise Nozzle is required, the supply line should be shut down at the shut-off located one length back and the nozzle opened to bleed the line. This will make it easier to move the nozzle and supply line while repositioning. Once in position, the officer supervising nozzle operations will order water started. This officer will then notify the IC that the nozzle is in position and ready to operate. The nozzle will not be operated until the IC has given approval.

Question 58

58. L-99 has been assigned as the ventilation support unit for a fire on the 33rd floor of a 45 story HRFPMD. Which designation listed below is not correct? AUC 349, 6.1
    A. The members assigned to operate the fans in the lobby shall be designated as the “vent group fire unit”.
    B. The member assigned to the roof shall be designated as the vent group roof.
    C. The entire unit, L-99, shall be designated as the “ventilation support group”.
    D. The officer of L-99 shall be designated as the “vent group supervisor”.

Answer 58

58. A

6.1 The unit assigned to respond with the PPFs to the incident location shall be designated the Ventilation Support Group. The officer shall be designated as the “Vent Group Supervisor”. The members assigned to operate the fans shall be designated “Vent Group Lobby Unit” and the “Vent Group Fire Unit.” The member assigned the roof shall be
“Vent Group Roof”.

Question 59

59. Research and field experience has proved that one fan (PPF) can provide the proper pressure in a stairwell up to 10 stories depending on conditions while two fans (PPF) will pressurize a 40 story building when properly positioned. L-99 is operating as the vent support
    group at a fire on the 22nd floor of a 35 story building. The 1st fan has been placed into operation on the ground floor to pressurize the attack stairway. Since the fire is above the 10th floor a second fan shall be set up outside the attack stairway on the floor? The pressure delivered to the attack stair by the fans (PPF) will be great enough to allow for up to_________ stairwell doors to be open and pressurization to remain effective.
    AUC 349 7.3

A. 21st floor/3
B. 22nd floor/2
C. 20rd floor/2
D. 19th floor/3

Answer 59

59. D

 Research and field experience has proved that one fan can provide the proper
pressure in the stairwell up to 10 stories depending on conditions, and two fans will
pressurize a 40 story building when properly positioned. If the fire floor is above the 10th floor or additional pressures are required to maintain the stairwell free of smoke, a second fan must be brought to three floors below the fire floor and set up, following the proper positioning (4 to 6 feet back, 80 degree angle). This will maintain proper pressure throughout the stairwell, up to a 40 story building. This same concept, of placing a fan on the ground floor and a second fan three floors below the fire, can also be applied to buildings greater than 40 stories.
Note: In buildings over 40 stories in height, the IC should consider special calling an
additional ventilation support group. The extra fans can be used to augment pressures in the stairwell.

 The pressure delivered to the attack stair by the PPF will be great enough to allow for up to three stairwell doors to be open and pressurization to remain effective.
However, all members should understand that keeping as many doors closed as
possible is the goal. Members are permitted to move from one area to another as long as they remember to close the stairwell door behind them.o close the stairwell door behind them.

Question 60

60. Setting up the positive pressure vent (PPV) fans require that certain distances and angles of the fans be adhered to. This will maximize the effectiveness of the PPV fans. Listed below are four types of ventilation methods that the FDNY uses. Which of the methods along with the
    distances and angles are correctly listed? (More than one correct).
    AUC 349, 7.2,8.1, 9.2, 10.2
    A. Positive pressure ventilation: Optimum placement of the fan is 4’ to 6’ from the attack stairway door on the ground floor at an 80 degree angle.
    B. Sequential ventilation: Fan should be placed in the lobby at the base of the attack stairway.
    C. Positive pressure mechanical ventilation of large areas: Fan will be set back farther than 4’ to 6’ from the exhaust opening at an 80 degree angle.
    D. Negative pressurization: If tarps are not available or the fan cannot be hung, then place the fan 6’ to 8’ back from the exhaust opening at a 30 degree angle.

Answer 60

60. A, C, D
61. 2 The ability of the fans to produce positive pressure relies on proper fan placement to create a seal and push air into the stairwell. Pushing fresh air into the area that needs to be pressurized or ventilated is the preferred method of positive pressure ventilation. The optimum placement of the PPF is 4 to 6 feet from the attack stairway door on the ground floor and directly facing the door to the stairwell at an angle tilt of 80 degrees. This placement in front of the doorway will create the proper seal at the stairwell inlet. The 80 degree angle tilt can be achieved by using the tilt angle index holes on the base on the fan frame. There are 5 tilt positions operated by a foot pedal. The fan shall be positioned to blow into the stairwell; it should not be placed in the stairwell. Placing the fan in the stairwell does not create any pressure in the stairwell. It may create higher CO levels and negative stack effect by pulling smoke and heat down the stairwell.

8.1 After fire extinguishment, the products of combustion can be ventilated vertically
through the attack stair. This is accomplished by placing a fan at the base of the evacuation stairwell, and pressurizing that stairwell. This procedure will create an area of high pressure in the evacuation stairwell and utilize the area of lower pressure in the attack stairwell to facilitate smoke removal. The evacuation stairwell will be contamination free for this type of ventilation.
Note: Placement of the fan for sequential ventilation shall be on the exterior of the
building with exhaust hoses in place. The goal of sequential ventilation is to replace the smoke and CO in the building with fresh air. Placement of a gas powered fan inside a building during sequential ventilation would negate the benefits of the operation.

 An inlet should be found opposite this exhaust opening that would allow the fans to push fresh air into the structure. The fans have to make a seal at the inlet. The fan
will be set farther back then the 4 to 6 feet used when pressurizing stairwells. The
angle of the fan shroud will remain at 80 degrees. A rule of thumb is that the exhaust opening should be double the size of the opening where the PPF is placed. This will allow minimal pressure to build while permitting a large movement of air.

10.2 To maximize the efficiency of this operation, the box fan should be hung in a window or doorway as high as possible. Salvage tarps should be used to create a seal around the operating fan, allowing the exhaust fan to create an area of negative pressure. When tarps are not used, churning of the interior air occurs limiting our ability to ventilate the area.
Note: An alternate method, when tarps are not available or the box fan can not be hung,
is to position the fan inside the contaminated area facing the exhaust opening 6 to 8 feet
back and tilted up at an angle of approximately 30 degrees. This positioning will form a seal of air around the exhaust opening preventing churning of the air and increasing efficiency.

Question 61

61. Members of a study group were discussing AUC 349 and made various points from different sections of the bulletin. Which is the only correct point listed below?
    AUC 349, 6.3, 6.5, 7.2, 8.2
    A. The priority order for the use of the PPF’s is to first pressurize the evacuation stairway, then pressurize the attack stairway, and finally venting of the public halls for smoke and CO control.
    B. This sequential ventilation process can be implemented when a building has high levels of CO or other contaminates. The process will begin on the top floor and continue on each floor until the CO is reduced to acceptable levels.
    C. When fans are in position, the IC shall be notified. Stairwell pressurization will not be initiated until authorized by the Incident Commander.
    D. A PPV fan can be placed in the stairwell with permission of the IC. Placing the fan in the stairwell will pressurize the stairwell however it may create higher CO levels and negative stack
    effect.

Answer 61

61. C

6.3 The ventilation support group supervisor shall inform the IC of the recommended
placement of the PPFs. Proper placement is based on the number of PPFs and personnel
available, the location of the fire floor, number of floors in the building and the stage of
firefighting operations. When fans are in position, the IC shall be notified. Stairwell
pressurization will not be initiated until authorized by the Incident Commander. All
members shall be notified that PPF operations are commencing. Communication with all units shall be maintained during the pressurization operation.

6. 5 The priority order for the use of PPFs is as follows:
7. Pressurizing the attack stairwell to support the fire attack, by controlling the smoke condition at the attack stair doorway and throughout the attack stairway.
8. Pressurizing the evacuation stairwell for smoke and CO control.
9. Ventilating the public hallways for smoke and CO control.

7.2 The ability of the fans to produce positive pressure relies on proper fan placement to create a seal and push air into the stairwell. Pushing fresh air into the area that needs to be pressurized or ventilated is the preferred method of positive pressure ventilation. The
optimum placement of the PPF is 4 to 6 feet from the attack stairway door on the ground floor and directly facing the door to the stairwell at an angle tilt of 80 degrees. This placement in front of the doorway will create the proper seal at the stairwell inlet. The 80 degree angle tilt can be achieved by using the tilt angle index holes on the base on the fan frame. There are 5 tilt positions operated by a foot pedal. The fan shall be positioned to blow into the stairwell;IT SHOULD NOT BE PLACED IN THE STAIRWELL. Placing the fan in the stairwell does not create any pressure in the stairwell. It may create higher CO levels and negative stack effect by pulling smoke and heat down the stairwell.

Note: This sequential ventilation process can be implemented when a building has high levels of CO or other contaminates. The process will begin on the ground floor or cellar and continue on each floor until the CO is reduced to acceptable levels. PPF exhaust should be vented to the exterior if possible to reduce the introduction of CO into the building. Electric fans can also be implemented in this situation.

Question 62

62. When operating PPV fans firefighters must realize that these fans run at high RPM’s and creates a large amount of airflow. Members must follow certain safety guidelines to ensure a safe and successful operation when using the PPV fans. Which point regarding safety procedures and the PPV fans is correct? AUC 349, 11.2, 11.5,11.6, 11.8
    A. If the need arises to move a fan in operation, the fan must be throttled down to its lowest RPM setting. The fan can then be safely moved to a different location.
    B. If a fan needs to be refueled at an operation, it shall be shut down. The fan can then be refueled inside a structure or at an outside location.
    C. When running the fans at an incident, exhaust hoses must always be attached to the operating fan in order to limit and control the introduction of CO inside the structure.
    D. PPV fans can be lifted by one member as they are lightweight. Eye and ear protection shall be worn whenever the fans are operating.

Answer 62

62. C

11.2 The PPF shall never be transported while in operation. If the need arises to move the
fan, it shall be shut down before transportation.

11. 5 PPFs should be lifted by two members whenever the fans need to come off the ground,
    e. g., on and off apparatus, up stairs. PPFs are heavy pieces of equipment. Damage to the fan and injury to the member could result.
12. 6 Fans shall never be refueled inside a structure. The possibility of the gasoline coming in contact with a hot exhaust manifold could result in a fire. If the fan needs to be refueled at an extended operation, it shall be shut down and moved to an outside area remote from any foot traffic. This remote area is necessary to assure safety as well as to not contaminate the fire area with what could be detected as an accelerant.
13. 8 When running fans at an incident, exhaust hoses must always be attached to the operating fan in order to limit and control the introduction of CO inside the structure.

Question 63

63. Lt. Smith was going over the process on using positive pressure mechanical ventilation to vent large areas or structures. Which point made by Lt. Smith about this process was not entirely
    correct? AUC 349, 9.2
    A. The wind is always a consideration in this operation. If the wind is striking the face of the building that we are using as an exhaust outlet then the efficiency of the fans will be greatly diminished.
    B. When the fire is controlled by the sprinkler or a hand line look for an exhaust opening in that area. Having the exhaust opening as far from and as low as possible to the seat of the fire minimizes the smoke damage to a structure.
    C. The fans should be set back further than the 4 to 6 feet used when pressurizing stairwells. The angle of the fan shroud should remain at 80 degrees.
    D. Using roll down doors can allow two fans to be placed side by side (parallel) blowing into a structure. A seal is created by adjusting the height of the roll down door and the set back of the fans.

Answer 63

63. B

 When the seat of the fire is determined and the fire is controlled by a sprinkler or
handline, look for an exhaust opening in that area. The higher the exhaust opening
the better. Having the exhaust opening close to and as high up as possible to the seat
of the fire minimizes the smoke damage to the structure.

Question 65

65. Members of E-99 have just arrived at a NYC Housing Authority Building for a report of a person stabbed in the lobby. Upon arrival members can see the victim lying on the floor of the lobby but when they attempt to open the door it is locked. The Officer of E-99 tries to use the
    key FOB to unlock the door however, it is not working. Members then call the NYCHA security phone number, via the dispatcher and also via a member’s cell phone, to have the door remotely
    unlocked. Both the dispatcher and the member with the cell phone are getting a busy signal. The Officer of E-99 then orders his members to force the door since the victim has just gone
    unconscious. After EMS arrives and takes over patient care members of E-99 are able to fix the door so that the door will lock and is secure. The officer of E-99 should take which action
    below?
    Multiple Dwellings Addendum 4, 3.2

A. Notify NYCHA via the dispatcher that the door was forced and in addition forward a letterhead report through the chain of command to the Chief of Operations with full particulars.
B. Notify NYCHA via the dispatcher that the door was forced and in addition forward a letterhead report to the administrative Division Commander with full particulars.
C. No action is necessary since the door was able to be secured prior to members leaving the scene and human life was in peril.
D. Forward a letterhead report through the chain of command to the Chief of Operations with full particulars. No other action is required.

Answer 65

65. A

3.2 Any unit that forces a NYCHA building entry door or elevator machinery room door
shall notify NYC Housing Authority via Borough Dispatcher that a door has been forced, even if the door is able to be secured. In addition, the unit shall forward a letterhead report through the chain of command to the Chief of Operations with full particulars.

Question 66

66. You are a Battalion Chief working a day tour in Battalion 19 and after lunch you receive a phone alarm for a fire in a multiple dwelling. The CIDS info says that the building is 6 stories, 100’ X 200’, and of class 3 construction. Upon arrival you note that the building is a large new law tenement and you see fire venting out of two windows on the 2nd floor and possibly auto exposing to the 3”* floor. You transmit a 10-75, give an all hands on arrival, and call for an extra engine and truck. As you assume command in proximity to the front of the building the Officer from the 2”’’ due truck calls you and says he has one room fully involved on the 3rd floor and can
    see fire extending up a pipe chase to the 4th floor. You then call your aide and have him transmit a 2nd alarm. Do you agree or disagree with your actions at this fire? 5.5.2
    A. Agree or B. Disagree

Answer 66

66. A

5.5.2 Additional units: Because of the severe life hazard, height, area and combustible construction of these buildings, an additional engine company and ladder company (beyond a full 1st alarm assignment) should be called for a medium fire condition. That is, when it is anticipated that two lines will be required. When additional units have been special called, they should be given instructions, by radio, regarding positions, masks, extra hooks, etc. If two floors are involved, or at extensive cockloft fires, it will generally be necessary to transmit a 2nd alarm. The time that it takes 2nd alarm units to arrive must be considered under these
conditions.

Question 67

67. You are a BC working a day tour in B9 and as you are responding to a fire in a HRFPMD. You are thinking about communication systems in these buildings. Which point listed below is correct regarding communication systems and their use in HRFPMD’s? 6.2.1

A. The 1968 NYC Building Code requires one-way voice communication from the fire
command center to all stairways and dwellings for all new R-2 buildings greater than 200’ in height. The 1st arriving Chief should avoid use of these systems.
B. The 2008 NYC Building Code requires two-way voice communication from the fire
command center to all stairways and dwellings for all new J-2 buildings greater than 200’ in height. The 1st arriving Chief may utilize this system to direct and control evacuation of the fire floor and the floors above.
C. The 1968 NYC Building Code requires two-way voice communication from the fire
command center to all stairways and dwellings for all new J-2 buildings greater than 125’ in height. The 1 st arriving Chief should avoid use of these systems.
D. The 2008 NYC Building Code requires one-way voice communication from the fire
command center to all stairways and dwellings for all new R-2 buildings greater than 125’ in height. The 1st arriving Chief may utilize this system to direct and control evacuation of the fire floor and the floors above.

Answer 67

67. D

6.21.1 HRFPMDs generally have limited or no building communication systems
available in the lobby that can be used by Chief Officers to control and direct
evacuation.
6.21.2 If a communication system does exist, the first arriving Chief may utilize this
system to direct and control evacuation of the fire floor, and floors above. Extreme conditions may require evacuation of the floor below.
Note: The 2008 NYC Building Code requires one-way voice communication from the fire command center to all stairways and dwellings for all new R-2 buildings greater than 125 ft in height. HRFPMDs with
communications systems should be entered into the CIDS program.
