FFP MD's 1-5 Flashcards
Where is an airshaft found
A space between buildings or between rooms within a building to allow air & light in
Describe Backstretch
FF’s pull off sufficient hose at location at fire, Engine then proceeds to hydrant. Hose peels off as Engine travels to hydrant
Fire Partitions 1938 Building Code
Furnishes area of exit, or refuge, & has fire resistive rating of at least 3 hours (Partition 3 syllables 3 hours)
Fire Wall: A fire-rated, smoke tight wall having protected openings designed to restrict spread of fire from 1 structure to another, or from 1 area of a structure to another. It extends _
Continuously from foundation to, or through, the roof with sufficient structural stability to withstand the collapse of construction on either side of it.
In-line pumping
Engine placed close to fire & receives its water supply through HL stretched between Eng & hydrant
Dates OLT
NLT
Class A NFP MD
Built before 04/12/1901
Tenements built on/after 04/12/1901 & before 04/13/1929
Built on/after 04/13/1929
Description OLT
3-7 stories in height, 20-25’ wide, 50-85’ deep, Class 3 NFP construction, 2 means of egress (interior stair & fire escape), 2-4 apts per fl, air-shafts, RR flats & interior stairs to cellar
What is the ever dangerous exception to RR flats that is a major concern for safety & must be relayed to IC immediately
Absence of a Rear Fire Escape
OLT w/4 apartments per floor will have what physical characteristic
Rear and front Fire Escapes
NLT 4/12/1901-1916 Characteristics
6 or 7 stories, 35-50’ frontage, 85’ in depth, 5-6 apts per fl, 1st fl (cellar ceiling) fireproof construction & unpierced, cellar entrance via exterior stairs, interior stairs fireproof & enclosed, 2nd egress= other stairs/fire escape, & steel “I” beam introduced
Newer NLT 1916-1929:
Floor area 150-200’, to avoid fireproof construction broken into 2500 sq/ft or less (25 is between 16-29), dividing walls go high as ceiling of top floor w/large undivided cockloft area, dumbwaiter shafts (2 apt may share 1), & exterior entrance to basement
NFP MD after 4/18/1929 (known as Apartment Houses)
Between 1930-1940 firewalls required to underside of roof boards & after 1940 top of roof boards, enclosed fire wall is 3000 sq/ft (1930 3000 sq/ft), limitation in height of 6 story/75’ bypassed for building built on grade, may have non-storage garages below where a sprinkler may be required.
Preferred suction on Engine for hydrant hookup for NFP MD
Side suction preferred- front suction may block out responding ladder company
NFP MD: Most cases 1st HL stretched via interior stairs to location of fire: Exception
Flame issuing from window openings onto fire escape & endangering people trying to come down fire escape
NFP MD: who chocks open the entrance door
NFP MD: Do not clutter interior stairs. After _ lines stretched up stairway, additional lines should be stretched via fire escape or window
1st member entering building
2 HLs
Can a roof HL be used to operate into a vent hole from the roof
Should NOT- decreases vent & nullifies action of HL operating on top floor. Roof line should only be used to prevent fire from extending past the trench, protect exposures, or extinguish fire that cannot be reached from below ex- cornice
Some fires in OLT- it may be necessary for 2nd/3rd HL to be stretched into Exposure 2 or 4 because
Fire has extended or may extend across narrow shaft or shafts between buildings
Discretion should be used breaking windows in apartments not involved in fire- efforts should be made to open these windows _
2/3 from top and 1/3 from bottoms
Officer must not permit material thrown out of windows and setbacks…“UNOPEN”
UNnecessarily, no material Onto roofs of building setbacks, Post FF always in yard or street below to prevent injuries, Examination of yard before discarding any material into yard, no material thrown onto Narrow shaft
How should a large hole in the roof be cut with portable saws
If possible the long side of opening should be at right angles to roof beams in order to provide venting of as many bays as possible
Can Engines be used to pull ceilings
Yes especially in larger NFP MDs with fire on top floor or cockloft
ICP at NFP MD
Once a Sector/Group Supervisor is assigned, Units assigned to such shall report directly to their Sector/Group Supervisor. Units not assigned to a Sector supervisor shall report _
In proximity to the front of the building
Directly to the IC
Fire in OLT/NLT is in a shaft extending into an exposure: Transmit
Fire OLT/NLT is in a shaft and extending into 2 exposures: Transmit
2nd Alarm
3rd Alarm
Fire in OLT/NLT on 2 floors: IC shall _
Special call Extra Engine & Truck. If no progress on at least 1 floor in short period of time 2nd alarm
Who shall make it known to IC & other members the manner in which floors & apartments designated
1st Officer inside of fire building
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
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
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
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
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
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
2nd HL OLT Cellar fire
Advanced into cellar by way of front/rear entrance to cellar (Note OLT cellar ceilings are NOT fireproof)
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
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
