Construction features of MD;s are correct in the following? more one correct.A- After 1916 Steel “I” beams were introduced to carry floor joists which couldn’t span the enlarged floor areas. These steel beams generally were supported by masonry walls.B- NLT erected bet 1916-1929 To avoid being required to be built of fireproof construction, the floor areas were broken up into units of 2500 square feet or less.C-Class “A” NFP multiple dwellings built after 4/18/29 The size of the area to be enclosed by fire walls is 3,000 square feet.D- MD built after 1901 The interior stairs are fireproof and enclosed in partitions of fireproof construction. Apartment doors are constructed of fire resistant materials.
correct B, C, DA should be after 1901page 3, 4 GS
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? more one correctA-flame is issuing from windows opening onto the fire escape and endangering people trying to come down the fire escape.B- may vary for store firesC- may vary cellar firesD- may vary for dumdwaiter firesE-all correct
E - 3.2.2 , 3.2.3There are other instances in which engine company operations may vary from the usual procedure of stretching to the origin of the fire via the interior stairs, such as store fires, cellar fires and dumbwaiter fires. These will be treated separately.
As for SOP for gas meters in building which of the follwing is incorrect?A-Gas meters are usually in the cellar but they may also be found in apartments and in public hallways.B-If gas meters are burning they should be allowed to continue to burn until the gas supply is shut off. C-If fire at the meter is extinguished before the gas supply is shut off, gas will continue to discharge and an explosion or flash fire may occur when the gas comes in contact with a source of ignition.D-If gas is leaking without being ignited, the gas supply should not be shut off. 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.
D IC should shut off3.5.9 GS
As a general rule, outside streams should not be directed into occupied buildings. which are correct about use of outside streams? more one correctA-Occupants should be removed first. However, in some cases, life safety or fire conditions may require that outside streams be used in occupied buildings. For example, to protect people on a fire escape or for fire in a store.B-Only the Incident Commander may order the use of outside streams. This may be the officer arriving first.C-Outside streams should be used in one position only as long as necessary to extinguish visible fire.D-Members inside the building must be warned, and moved to safe location before outside streams are directed into the building. This safe location must be verified by radio or personal contact, by the Incident Commander of the fire.
A- ic Heavy fire in store3.5.10
For Line placement for a cellar fire in OLT , which is incorrect?A-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.B-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 of course, the fire is minor.C-Ventilation must be provided at the roof over the stairway, at the top of the dumbwaiter shaft and other shafts and vertical openings.D-Ventilation must also be provided by chocking the door open at the top of the interior cellar stairs after all of the occupants have been evacuated.
D ICshould readD-by intermittently opening and closing the door at the top of the interior cellar stairs after all of the occupants have been evacuated.4.2.1
The Incident Commander must keep in mind that fire in these 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. which is IC?A- For a fire in an Old Law or New Law Tenement, special call an extra engine and truck for fire on two floors.B-If progress is not made on at least one floor in a short period of time, transmit a 2nd alarm.C-If fire is in a shaft extending into an exposure, transmit a 2nd alarm.D-If fire is extending into an exposures, transmit a 3rd alarm.
D IC should read-If fire is extending into two exposures, transmit a 3rd alarm.3.4.4 GS
the following are general operations in OLT’s .which are correct , more then one?A- If there is fire in two apartments on a floor or fire involves an apartment from front to rear, two lines may be needed on that floor.B-if people are out on the fire escape when the first engine company arrives, and it appears that those people are in danger because of fire coming out the windows, then two lines should be stretched. One line to remain in the street to protect the people on the fire escape and the other line to be taken into the building.C-Engine companies with lines in exposures can extinguish a great deal of fire in the fire building by operating across a shaft. However, this should not be done without permission of the Incident Commander as it may drive the fire at members advancing from the interior.D-The absence of a fire escape on the front of an OLT will usually indicate that the apartments are railroad flats.Corner buildings may be exceptions to this general rule.E- all correct
E all correct4.1
Store fires in OLTs may involve a large amount of combustible material. A 2 1⁄2” line should be stretched for large volume fires. where is second line stretched?
4.2.2 A, G GSsecond 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.-Stores in OLTs may have a door which opens into the public hallway on the first floor. The first floor public hallway should be examined immediately to determine whether the means of egress for the occupants of the building is in danger from the store fire. If so, a hoseline should be positioned to protect the interior stairs.
Fires in stairways in OLT’s present a serious situation since the stairway is the primary means of egress for the occupants. Which of following is Incorrect for a stairway fire in a OLT NFP?A-The first hoseline should be stretched up the stairway, operated to extinguish fire, shut down and advanced further up the stairwayB- First line Should must be operated up the wellhole to cool off the hall and stairs above.C- This procedure for first line should be repeated until line is advanced to the top floor.D-A second line should follow to finish up extinguishing operations and to serve as protection for members advancing the first line.
B IC should read-When possible, the line should be operated up the wellhole to cool off the hall and stairs above. 4.2.4 GS
Of the following which are correct for SOP for Air and Light and Dumbwaiter Shaft Fires in OLT NFP? more one correctA- A hoseline should be stretched to the nearest point from which water can be directed onto fire in the shaft. Sufficient hose must be stretched to reach the upper floors of the building.B-For fires in rooms in the vicinity of a shaft, the line should be immediatly operated up the shaft to extinguish fire and cool the shaft.C-A second hoseline may be necessary if it appears that fire might have extended into the adjoining building.D-Prompt examination must be made to determine if fire has extended into buildings, and windows must be closed to prevent fire or flying brands from entering.
A, C, D are correctB IC should readFor fires in rooms in the vicinity of a shaft, after the fire in the room has been controlled, the line should be operated up the shaft to extinguish fire and cool the shaft.4.2.6 GS
True/FalseAny indication of collapsing floors during fire operations should be promptly reported to the Incident Commander so that units can be withdrawn to safe positions. These indications of possible collapse may include plaster ceilings falling, floors or ceilings sagging, and unusual creaking noises.
True 4.3.1 D GSFYIWhen the metal cornice at the roof has been involved by heavy fire for a considerable time the cornice or parts of it may suddenly fall. It is important to be aware that this may happen and to keep members, and other people away from the front of the building. Members stretching lines up the front fire escape or operating from the front fire escape must also be warned and moved to a safe position when it appears that the cornice may fall.
Of the following stairs which are tremendous asset in heavy fire operations on the top floor.A-Wing stairsB- Transverse stairsC- isolated stairsD- straight run stairs
B- Transverse stairspage 22, 23 GS-Transverse stairs-these stairs usually are 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.
the following are statements about BC’s SOPat Class “A” NFP MDs built after 1901 (mostly H types). which are correct more then one?A- 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.B-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.C-Additional chief officers: When transmitting 2nd or greater alarms for fires which have entered the cockloft of large “H” type buildings, the IC should consider special calling additional battalion chiefs to cover critical sectors and/or exposures.D-These additional battalion chiefs could be assigned as top floor sector supervisor, roof sector supervisor, or as needed.E-all correct
E all corectpage 26, 27 5.2.3 GSFYI– If an Operations Section is established, sector/group supervisors will generally report directly to the Operations Section Chief, who would then report to the Incident Commander. If Branches are established, sector/group supervisors will report to the Branch Director they are assigned to, who will then report to the Operations Section Chief.-sector/group -sector/group supervisors -Branches-Operations Section Chief
