OP - CLASS #5 - Week of 101314FFP – Ventilation, Comm. Man Ch. #8, AUC #151, TB – Tools #Ropes 1, 2, 3 & 4, Haz Mat #5, 7 & 11 Instructor Capt Ken Ruggiero Flashcards
PART I – VENTILATION PROCEDURES:
1. When reading a fire department bulletin it is important to read the glossary in the beginning of the bulletin. Sometimes certain points are mentioned in the glossary and not in the bulletin. Which point below is correctly listed? Glossary
A. The growth stage (also known as rollover) is where the fire begins to spread across the ceiling of the fire compartment. When observed at the ceiling level, rollover shall be taken as an indicator the fire conditions are rapidly deteriorating and flashover may be imminent.
B. Modern content fires are fires that involve hydrocarbon and synthetic based contents such as foam, rubber, and rayon. Modern fires have a relatively low heat release rate when compared to the natural fiber products found in legacy fires.
C. Ventilation is the controlled and coordinated removal of heat and smoke from a structure replacing the escaping gases with fresh air. This exchange is bi-directional with heat and smoke exhausting at the bottom and air flowing in towards the fire at the top.
D. Smoke is a toxic mixture that contains numerous poisonous gases such as carbon monoxide, hydrogen cyanide, and phosgene. Smoke is not considered a fuel source.
- A
- The ventilation bulletin addresses the progression of a modern fire versus a traditional fire. Listed below are the steps of a modern content fire’s progression. Please place these steps in the correct order in which they occur. 2.1.5, 2.1.6
- A rapid growth stage
- Early oxygen limited decay stage
- Incipient stage
- Ventilation induced flashover
- Second decay stage
- Rapid second growth stage
A. 3, 2, 4, 1, 5, 6 B. 1, 3, 4, 6, 5, 2 C. 3, 1, 2, 6, 4, 5 D. 2, 1, 3, 5, 4, 6
- C. 3, 1, 2, 6, 4, 5
- There are a number of contributing factors that can affect ventilation tactics. One of the factors mentioned in this bulletin is energy efficient construction which when coupled with a modern content fire can pose a significant danger to firefighters. Which type of heat mentioned in this bulletin will be absorbed by a members PPE at a faster rate than the others and put members at a greater risk of burns? 3.1
A. Radiant Heat
B. Convective Heat
C. Conduction
- B
- On each response, officers and firefighters must conduct and initial size up which includes the type of building, occupancy, and conditions on arrival. Part of this initial size up includes a ventilation profile of the fire conditions. Which point listed below concerning a ventilation profile size up is incorrect? 4.1
A. The ventilation profile should note the location where smoke or fire is venting from the building and an evaluation of the volume, pressure, and velocity of the smoke venting from the building.
B. Fire and smoke should be venting outwards and upward. If the smoke and fire are venting downward, horizontally, or pulsing from an opening, this indicates the fire conditions may be wind impacted.
C. A legacy or a modern content fire will always generate enough pressure to push smoke from the fire area or fire building, regardless of the stage of the fire.
D. Heavy flames out of the windows are usually an indicator of high heat and smoke conditions within the interior, including areas remote from the fire. If the fire is already vented on arrival we must still control and coordinate all ventilation tactics.
- C
- During afternoon drill members were discussing horizontal ventilation tactics and made the following points. Which point made should be corrected by the Officer of Ladder 101?
7.1, 7.2, 8.1, 8.2
A. All interior and exterior horizontal ventilation tactics must be controlled, communicated, and approved by the Ladder Co. officer inside the fire area to be vented.
B. The Ladder Co. officer inside the fire area shall maintain situational awareness, evaluate information from members operating on the exterior, evaluate wind conditions, and ensure door control at the fire area entrance.
C. Members operating on the exterior shall notify the Ladder Co. officer when they are in position to ventilate for search or ventilate for extinguishment.
D. Horizontal ventilation tactics include controlling door and window openings until a charged hose line is advancing into the fire building.
- D
- With the introduction of the new ventilation tactics many things have changed regarding vertical ventilation at fires. The 1st arriving roof firefighter at a fire on the 4th floor of a 5 story old law tenement would know that he can perform initial vertical ventilation in which choice(s) below? 10.2
A. When he communicates with and receives approval from the Ladder Co. Officer operating inside the fire area to be vented.
B. The roof FF may perform vertical vent without direct communication with the Ladder Co. officer if he hears radio transmissions that the interior team has door control on the fire floor.
C. The roof FF may perform vertical vent without direct communication with the Ladder Co. officer if he hears radio transmissions that a hose line is being stretched into the fire building.
D. The roof FF may perform vertical vent without direct communication with the Ladder Co. officer if he hears radio transmissions that a charged hose line is advancing into the fire apartment.
- A, B, D
- Units are operating at a fire on the 3rd floor of 6 story old law tenement. The fire is in the front of the building and there is a front fire escape. There is extension to the 4th floor in the apartment directly above the fire apartment. The 1st due truck inside team is operating in the fire apartment on the 3rd floor and the 2nd due truck inside team is operating on the floor above the fire in the apartment directly above the fire apartment. The O/V and LCC from the 1st due truck are on the fire escape at the window to the fire apartment on the 3rd floor awaiting permission to vent the window. The O/V and the LCC from the 2nd due truck are on the fire escape of the 4th floor and are also awaiting permission to vent the window on the floor above the fire. While awaiting on the fire escape both teams hear the officer of the 1st due Engine call for water and shortly thereafter they hear the officer tell command that they are knocking down visible fire on the 3rd floor. After hearing these two transmissions the OV and LCC of the 1st due truck vented the windows to the fire apartment on the 3rd floor from the fire escape. Do you agree or disagree with the actions of the OV and LCC from the 1st due Truck? 11.4
A. Agree or D. Disagree
- D
11.4 The member on the exterior waiting to perform the horizontal Ventilation for
Extinguishment of the immediate fire area shall listen for the following transmissions
from the Engine Company Officer:
The notification from the Engine Officer to the Engine Chauffeur to start water.
“E-162 to E-162 chauffeur, start water.”
The notification from the Engine Officer to the IC, “E-310 to Battalion 58, we are
knocking down visible fire.
The two transmissions above are an indication to the exterior member to prepare to
conduct Ventilation for Extinguishment. Before venting the window(s) the member must
communicate with and receive approval from the Ladder Company Officer inside the fire
area to be vented. “L-3 OV to L-3, ready to vent.” “L-3 to L-3 OV 10-4, vent the
windows.”
- In regards to the situation in question 7 above, the 2nd due OV and LCC hear the officer of the 3rd due Engine call for water and shortly thereafter hear him tell command that they are knocking down visible fire on the 4th floor in the apartment directly above the fire. The OV of the second due truck then asks the officer (his officer) of the 2nd due truck for permission to vent the window of the apartment on the 4th floor directly above the fire apartment. The officer of the 2nd due truck gives the OV and LCC from the 2nd due truck permission to vent the window, they vent the window based on the officer’s response. Do you agree or disagree with actions of the 2nd due OV and LCC? 11.4
A. Agree or D. Disagree
- A
9. When a fire progresses past the incipient stage, the fire area is considered an IDLH atmosphere. No member shall enter, leave, or operate in an IDLH atmosphere unless the member teams up with at least one other member and remains within visual or voice contact with that member. The only exception to this policy is when a known life hazard is found and immediate action could prevent the loss of life. A know life hazard is defined as a victim who can be seen or heard by the rescuer or if a member has information from a credible source or a person at the scene indicating the location of the life hazard. If a Captain and a Lieutenant are the only officers on the scene of a fire where an IDLH is present and a member takes individual action to address a known life hazard which officer is responsible to forward a report detailing full particulars of the incident to the Chief of Operations? 12.3 A. The Lieutenant B. The Captain C. The 1st to arrive Battalion Chief D. The members Officer
- B
- There is certain criteria that members must be aware of and adhere to when performing ventilation for search. Which point regarding these criteria is not correct? 12.6
A. The Ladder Co. Officer shall be notified when a search team enters from the exterior to conduct a search for a known life hazard or when they are entering to conduct standard search procedures.
B. If the Ladder Co. Officer and the interior team have quicker access to the location of a victim or to the area requiring a search, the Ladder Co. Officer may decide to disapprove the entry to search in order to limit any negative impact caused by the additional ventilation.
C. Once a decision has been made and approval has been granted to enter, the member should clear out the window for access and be cognizant that a new flow path has been created.
D. Upon completion of clearing the window, immediately enter and assess the smoke and heat conditions to determine if the area is tenable. If conditions prevent access, immediately notify the Ladder Co. Officer of the situation.
- D
Upon completion of clearing the window and before entering, reassess the smoke and
heat conditions to determine if the area is tenable. If conditions now prevent access,
immediately notify the Ladder Company Officer of this situation.
- The O/V from L-33 has just entered a bedroom on the 2nd floor of a private dwelling. Upon entering the room the O/V finds an unconscious victim on the floor about 10’ inside the room. The door to the room is open and the fire is now lapping into the hallway on the 2nd floor from a bedroom across the hall. The OV from L-33 then transmits a 10-45, gives his location, and his planned exit route. The OV would be correct to take which action next? 12.6
A. Call his officer and ask for assistance.
B. Immediately remove the victim.
C. Isolate the room and proceed with the rescue effort.
D. Shelter the victim in place and share his facepiece with the victim
- C
- True or False? Upon entering a room from the exterior members should immediately begin a search and upon locating the door to the room they should close the door to isolate the room. 12.6
A. TRUE or D. FALSE
- D
After venting and entering, the priority action for the member is to isolate the area by
closing a door before conducting the search (VEIS). By isolating the area the
conditions in the room should improve as the closed door will stop the flow of fire
conditions and the window will provide an exhaust vent allowing a safer and more
effective search.
Search the room and locate any victim. If a victim is found immediately transmit
radio code 10-45, include your location and planned exit route. The Company
Officer and IC shall take necessary action to support the rescue effort.
Note: If a victim is found prior to isolating the room, the member shall isolate the
room and proceed with the rescue effort.
PART II – AUC 151:
1. There are many different variables and terminology regarding brush fires that members should be familiar with when operating at or anticipating brush fires. Which is the only correct point listed below? 3.2.1, 3.4, 3.3
A. Weather is the controlling factor affecting the severity and incidence of brush fires. High humidity, winds in excess of 20 MPH, and little or no rainfall for the preceding 3 or more days can cause serious brush fires to occur.
B. The head of the fire is the leading edge of a moving fire while the rear of the fire is the side opposite the head. Looking at the fire from the head of the fire, the left side is called the left flank and the right side is called the right flank.
C. Crown fires burn along the tops of trees, extending by direct flame contact and heat waves. These fires are fast moving and the most common type of brush fire encountered in New York City.
D. Surface fires burn grass, weeds, small trees, leaves on the ground. Bog fires start on the surface and burn downward into the soft spongy ground and burn slowly. This type of fire is common in dried out swamp or marshlands
- D
- BFU’s shall be staffed by a Lieutenant and 2 firefighters from 0900 to 1800 hours during the period of March 17th through April 30th and October 17th through November 30th on a MSOT basis.

to 1800 hours during the period of March 17th through April 30th and
October 17th through November 30th, on a minimum manning overtime
basis. Exceptions can be made due to inclement weather conditions that
would decrease the probability of brush fires.
- Lt. Smith is working a day tour in BFU 6 which is quartered with E-321. During the tour BFU 6 is sent to Staten Island. After operations are concluded one of the firefighters tells Lt. Smith that a tree branch hit the windshield and cracked it. Lt. Smith should be guided by which point(s) below? 4.5.5 C, 4.5.7

- During drill members were discussing the capabilities and limitations of brush fire units. Each member made a correct point except one member, please choose the incorrect member.
4.5.14, 4.5.15, 5.1.2, 5.1.3, 5.1.4
A. Brush fire units cannot knock over trees, go through hedgerows, or traverse streams and ponds. BFU’s can be supplied in place and operate as a stationary manifold to supply handlines, forestry hose, or booster hose for prolonged operations.
B. Units responding into a brush fire may detect sparks and embers starting additional fires downwind and a distance away from the original fire location. Units should stop to extinguish these fires under all circumstances.
C. Units are not to self-commit to operations unless structures are exposed. In this case, the officer is to notify the dispatcher for relay to the IC and request any additional assistance deemed necessary.
D. Units operating remotely and completing an assignment are not to go 10-8. Officers shall advise the IC and await for additional orders, for possible redeployment.
- B
5.1.3 Units responding into a brush fire may detect sparks and embers starting
additional fires downwind and a distance away from the original fire location.
Officers should report this information to the dispatcher for relay to the IC.
- Lt. Smith is working a day tour in an Engine Co. on Staten Island. Lt. Smith knows that all Engine Co’s assigned to Staten Island and BFU’s are equipped with 1” lightweight yellow hose in 100’ foot lengths also known as forestry hose. While operating at a car fire in a vacant lot Lt. Smith sees a member stretching the forestry hose to extinguish the car fire. Lt. Smith would be correct to follow which point below? 4.7
A. Have the member continue to stretch the forestry hose since the car is about 75’ feet away from the Engine and only 1 length of the forestry hose will be required.
B. Tell the member to use 2 lengths of 1 ¾” hose instead of the forestry hose.
- B
4.7.3 Forestry hose is intended for outside wildland operations only, and is not to be
used for any other type of operation.
- When dealing with brush fires it is important to be aware of the proper tactics to use in order to quickly extinguish the fire and to do so safely. Of the following operational tactics used at a 2nd alarm brush fire, which tactic(s) were carried out improperly? (More than one incorrect).
5.4, 4.4.1
A. The 1st arriving Engine Co. hooked up to a hydrant even though exposures were not in danger since hydrants are the best positive water source.
B. Heavy reliance was placed on Indian pumps, brooms, booster lines, and conventional 1 ¾” hose during the initial attack.
C. A 2nd alarm Engine Co operated at the top of a hill in front of the fire in order to protect an occupied 3 story MD. At the same time the attack of the fire started at the bottom of the hill.
D. Attempting to break up heat waves by use of a water curtain is generally ineffective. Instead, utilize streams to apply water directly onto exposures.
E. Hose streams were directed first at the flames burning above the brush and then directly at the burning brush.
F. Units advanced through burnt out areas to attack the fire since it is safe to operate from burnt out, blackened areas because there is no fuel left to burn.
- A, B, E
Heavy
reliance should be placed on the use of Indian Pumps, brooms, and booster lines from
BFUs.

- While fighting a brush fire, units may find themselves out of handie talkie range since large areas may have to be covered on foot. When a unit is out of range when using handie talkies, radio communications may have to be accomplished in which manner below? 5.9
A. Have members switch to a 5 watt channel on the handie talkie.
B. Have members switch to channel 9, a digital channel.
C. Have members use the POST radio carried by BFU’s.
D. Call the borough dispatcher on the borough radio frequency.
- D
5.9.2 Units may be out of handie-talkie range and radio communications may have to
be accomplished via borough dispatcher on the borough radio frequency.
- Which is the only correct point regarding Engine, Ladder, and Special Unit operations at brush fires? 5.6, 5.7, 5.8, 5.10
A. Engine Companies on the initial alarm should concentrate on protecting exposures and hooking up to hydrants to ensure positive water source.
B. Fire attack should begin immediately, even if exposures are endangered. This will ensure a quick knockdown of the fire.
C. Use extreme care on driving on unpaved roads. If road conditions are doubtful, members should precede the apparatus on foot. If still in doubt do not proceed.
D. Rescue and Squad Companies are not used at brush fires and only respond if special called by the IC.
- C
- Safety is paramount at all operations. Brush fires pose unique safety hazards that firefighters must be aware of. Which point is incorrect regarding safety at brush fire operations?
5.11
A. All body parts should be covered. Recognize and avoid growths of poison ivy, poison oak, and sumac. Avoid walking through high piles of rubbish or lumber since nails, glass, or other sharp objects may cause puncture wounds.
B. Do not use make shift bridges to cross creeks. A make shift bridge failing under a members weight could drop the member into water deeper than it appears.
C. Use extreme caution when brush fires burn near utility transmission lines. Use extreme caution when operating hoselines beneath high voltage lines and ensure the use of fog tips for added protection.
D. Avoid contact with any wildlife during operations. At night operations, utilize available portable and apparatus lighting systems for safety.

- Capt. McMeister is working a day tour in Ladder 105, which is a CPC truck. Capt. McMeister is trained in CPC and was the top gun in his CPC class. Ladder 105 has been special called to a haz mat incident where they will be used as a CPC unit. Capt. McMeister would know which point below to be incorrect? Section 5
A. Capt. McMeister knows that he will only don a CPC suit if the situation indicates that a suit is required in order to properly supervise the unit’s operation.
B. Examples of proper supervision include where the entry team would not be in line of sight, any type of entry team operation, and where the operation requires a number of entry teams.
C. On arrival the CPC unit officer shall report to the IC for a briefing. The 1st arriving CPC Unit Officer will recommend to the IC the entry point into the hot zone (based on his/her training, initial briefing, and size up), and then establish the CPC unit assembly area adjacent to the entry point.
D. Any critical or pertinent information received from the teams must be immediately relayed up the chain of command. The CPC officer will also ensure identity tags are used and placed on suits.
- B
The CPC Unit Officer shall not don a
chemical protective suit unless the situation indicates that a suit is required in order to
properly supervise the unit’s operation. Examples of this would be where the Entry team
would not be in line of sight, a complex Entry team operation, or where the operation
requires a number of Entry teams.
- After a briefing with the IC at the scene of a haz mat incident where a CPC unit will make entry into the exclusion zone, Lt. Smith decided to establish a 2nd channel to ensure adequate communication capabilities with members of his unit. Before directing his members to switch to handie talkie channel 3, Lt. Smith consulted with the IC, who also agreed that a 2nd channel should be established at this incident. Do you agree or disagree with the actions of Lt. Smith?
