25
Who shall make it known to IC & other members the manner in which floors & apartments designated
1st Officer inside of fire building
26
Location of Gas Meters in NFP MD Can outside streams be directed into occupied buildings
Usually in cellar, but may also be found in apartments and public hallways Should not be done, but may have to in order to protect people on fire escape or for fire in a store
27
Some situations which may call for use of outside streams "DECL"
Diminish heavy fire so an interior attack can be made, Exposure protection, Confine fire, protect Life by putting stream between fire & occupants
28
Can the 1st arriving Officer order the use of outside streams When can outside streams commence
Only IC can order- but if the 1st arriving Off, you are the IC Once members inside building are warned & moved to a safe location. Includes verification by radio/personal contact by IC
29
Can a HL be used across a shaft Tenements: Absence of fire escapes usually indicate RR flats- Exception
Yes it can extinguish a great deal of fire, however, should not be done without permission of IC Corner Buildings
30
Cellar fire OLT: 1st HL stretched to _
To cellar entrance door located inside building under interior stairway on 1st floor. Remain at this position. Do NOT advance down unless fire is minor
31
What is different in regards to the cellar door for fires in OLT vs PD
OLT: open & close door at top of interior stairs intermittently after all occupants evacuated to help ventilate PD: Keep door closed
32
2nd HL OLT Cellar fire
Advanced into cellar by way of front/rear entrance to cellar (Note OLT cellar ceilings are NOT fireproof)
33
OLT Store Fire: stretch 1st HL
2 1/2" for large volume of fire w/a 2nd line stretched to entrance hallway. If 2nd HL not needed on 1st floor, advance it to floor above the fire
34
Can plate glass windows be vented while a 2 1/2" line is being stretched for a store fire in an OLT
NO- charged line must be ready before store vented. Be aware that metal ceilings can communicate heat to floor above
35
What must be examined immediately in stores in OLT
Doors which open into public hallways on 1st floor. Examine immediately to determine whether means of egress for occupants is in danger from store fire. If so stretch, HL to protect interior stairs
36
What may be in rear of stores in OLT How are stairway fires handled in OLT
Living quarters. Search rear ASAP 1st HL stretched up stairway, operated to ext fire, shut down, & advanced further up. Repeat to top floor. 2nd HL shall follow
37
Are Trench cuts performed in OLT fires in cockloft
May be necessary but usually such fire extinguished from below after an adequate vent hole cut over fire
38
According to MD's How shall fires in rooms in the vicinity of a shaft be handled:
After fire in the room has been controlled the line should be operated up the shaft to extinguish fire & cool the shaft
39
Are collapses in OLT a problem
Due to short span of beams 25' & floor not being heavily loaded- collapse of floor in OLT usually not a problem
40
At fires in OLT the danger of spread of fire to exposed building is great. Which exposure is in the greatest danger
2 & 4 usually closer to fire building & layout of shafts effects these exp. Rear usually not as serious being 10-25' away
41
Some OLT are being used as SRO- what layout of the rooms is required
Each occupant must have access to both means of egress (stair & fire escape) w/o having to go through another person's room
42
Where are sprinklers required in SRO OLT
In each room and stairway. Must also have interior alarm & exit lights & signs
43
Who supplies sprinklers at SRO OLTs Due to construction features & life hazards in OLTs, particular attention must be directed to an initial search of _
No roof tank- supplied from water main in street. FD cannot supply Top flr apts regardless of fire location (expect heavy smoke build up at top floor apartments)
44
What may have to be done if Roof FF reports Party Wall Balcony Fire Escapes in rear of buildings
A HL may have to be stretched to rear to protect occupants & FF's, PL may have to brought to rear, & IC should consider calling an additional Ladder to aid in search & rescue
45
According to today's Building Code H-type apartments are required to be divided into areas of not more than _ sq ft
3000 sq ft
46
H-type differs from older tenements & newer hi-rise MDs in that there are 3 structural elements to support structure
Masonry bearing walls, Wood beams to support flrs & roofs, & Structural steel columns, beams, & girders (Older Tenements Masonry & Wood)
47
Some Disadvantages of Steel
Heat it expands allowing bulging, moving, & collapse, Steel can fail at higher temps, & I-beams can act as channel rails to allow fire to extend from 1st floor into cockloft
48
Once fire is knocked down in H-types & opening up begins you detect a column. What must be checked immediately
Location above the fire
49
If Roof FF detects a pipe on the roof that is hot to the touch, what must be done
Top floor examined and notifications made to IC & Officer
50
Once fire floor ID this area shall be known as Supervisor on fire floor known as
Fire Floor Sector Fire Floor Sector Supervisor; On floors above Floors Above Sector Supervisor
51
It's of vital importance that before a line is committed for a fire in an "H" type building _
Exact location of fire determined (CR w/Subways). Every effort shall be made to get 1st HL into operation before additional lines stretched
52
If you have stairs wrapping around an elevator shaft, it can make your stretch difficult. To alleviate this problem _
Use a rope to pull a HL up to the floor below the fire via the outside of the building, then up interior stairs to fire floor
53
Which ladder is preferred in front of fire building for H-Type buildings If a TL Stream is used for an H-type fire, where shall it be operated first
Tower Ladder- ability to use LCS Direct at windows in throat first, then advance toward front of the building, and finally operate into front windows
54
Roof access for H-Types
Primary means Winged or Isolated Stairway in same building (NO Transverse) or in an adjoining building if feasible. This allows the AL to be used to vent windows and afterward raised to the roof as a means of egress for members on the roof
55
Medium Fire condition in H-Type and it's anticipated 2 HL's will be required: Two floors of fire in Store in H-Type: 1st line stretched to store & extinguished fire. The 2nd HL shall be placed _
Extra Engine and Truck Back up the 1st HL, if not needed to back up, 2nd HL should be advanced to floor above the fire (if 2 HL's needed in store, 3rd HL shall be stretched to floor above)
56
Are cellars in H-Types fireproof Can a Company Officer be assigned as a Roof Sector Supervisor
Yes cellar concrete & rated for 2 hour fire resistance Yes until a Chief Officer can be assigned
57
Initial roof cut in an H-type A Trench may be cut, but should NOT be opened _
Coffin cut 3' X 6'. 2 saws shall be put into operation Until there is an adequate vent opening over the fire. Ideally trench should be precut, but NOT pulled
58
_ or more inspection holes may be cut on _ side of trench. When fire reaches the inspection hole _ 3 Sectors in H-types
2/more, Fire side, precut Trench is pulled Fire Floor Sector, Roof Sector, Floor Above Sector(s)
59
To be effective, Trench must be properly located, at least _' wide, and cut wall to wall or other suitable fire stop such as a stair or elevator bulkhead
3'
60
Trench should be cut about _' from initial vent hole. It should be cut at narrowest roof section taking advantage of bulkhead structure, outside walls, skylight, etc. (Do/Do Not) depend on firewalls constructed within the structure
20'; Do NOT
61
Are personnel allowed on fire side of Trench
Keep all personnel off roof on fire side of trench
62
The most probable point for vertical fire extension will be _
Vertical steel channels (in buildings that have steel frame construction). Fire in channel rails necessitate opening up above & at top floor ceiling for extension into the cockloft
63
Any time fire enters a vertical void _
Top & bottom must be checked for extension
64
A Fire Escape in the throat often spans the firewall & indicates _
2 separate apartments in throat vs One apartment in the throat that may span firewall w/NO fire escape & have 2 interior exits (1 stairway in 1 wing, & other to adjacent wing)
65
Can a HL be used into a trench

T/F Well hole stretch OLT: at least 1st length of hose should be brought up to the flr below the fire & the hose strap attached to prevent hose from slipping back down the well hole of the stairway. When performing the well hole stretch, it's important that the HL is removed from the well on the fl below the fire
False At least the 1st length of hose should be brought up to the fire floor and the hose strap attached to prevent hose from slipping back down the well hole of the stairway.
72
T/F Serious problems at cockloft fires is to determine extent of the fire. To do this it will be necessary to get all apts open on top fl & begin opening up above original fire area & move further away to determine the extent of the fire area
False it will be necessary to get all apts open on the top floor, make openings to find the extent of the fire, get ahead of the fire and work back to the original fire area.

15'
77
Portable ladders may be placed over weakened, damaged, or burnt-out stairs in order to safely gain access to upper stories of bldg during stairway fires. The preferred ladder is _
Extension ladder rather than straight ladder. Butts shall be supported by the floor at the base of the stair, while both upper beams at tip of ladder rest on upper fl landing for proper support
78
T/F: The part of the bldg connecting each wing shall be designated the throat & shall be referred to as the throat between A wing and B wing
True
79
Some cocklofts in H-types are as much as _ feet deep
As much as four feet deep
80
If any hot spots are found that require examination, small holes can be made for a visual check. Should any fire be encountered, notify _
IC & immediately go to top fl & check termination point of this void for any ext to cockloft area. If fire found- HL at that point & the roof opened above
81
2 Incorrect A. 20' straight ladder is the preferred choice to bridge OLT stairs B. Butts shall be supported by the floor at the base of the stairs C. Both upper beams at the tip shall rest on upper floor landing for proper support D. When properly placed, this ladder should only be used for emergency egret from above

2 incorrect A. Stairway fire- 1st HL should be stretched to top of stairway, operated to ext fire, shut down & advanced down the stairway B. Cockloft fire- may need to utilize Cockloft Noz carried in all Division vehicles and Squad C. Shaft fire- HL stretched to shaft's lowest access point to direct water onto fire. Sufficient hose must be stretched to reach upper floors of the bldg D. Due to short span of floor beams (20-25') and floors not being heavily loaded, collapse in OLTs is usually not a problem
A C Stairway fire- 1st HL stretched up stairwell, operated to ext fire, shut down & advanced further up stairway. When possible operate HL up well hole to cool off hall & stairs above. 2nd HL should follow to finish up ext ops & protect 1st HL Shaft fires- HL stretched to nearest point from which water can be directed onto fire in the shaft
83
Which would require enforcement action SRO on OLT A. Interior alarm, exit lights, & signs are all present & operational B. Layout of rooms is so that each occupant has access to both means of egress (stairs & fire escape) without having to go through another person's room C. Sprinklers are in the stairwell but not in the rooms D. Sprinkler system has no roof tank E. Sprinkler system cannot be supplied by FD

C: Roof FF made sure the hook was perpendicular to the lath when penetrating the ceiling. D: OV trimming a window started prying out midway along a side.
A. MD 7.4.1 D B. Cut floor at a 60 degree angle and on a bias. MD 7.4.2 B C. parallel to the lath. MD 7.1.4 A D. start at the top or bottom corner or joint and work along prying the molding out from the wall. MD 7.4.3
85
H-type incorrect A: All available engine companies should be used to stretch the first line. B: For store fires, the second line should be used to back up the first line. C: Engine companies arriving after the manifold is set up should be informed by the Satellite officer as to the size and number of lengths of hose to bring to the manifold for stretching to their point of operations. D: The exact location of the fire must be determined before a line is committed in an "H" type building.
C. 5.4.3 Engine companies arriving after the manifold is set up should be informed by the Incident Commander as to the size and number of lengths of hose to bring to the manifold for stretching to their point of operations.
