OLT's were built before 4/12/1901. They had 2 means of egress which were almost always?
Interior stair and fire escape
These building usually had apartments in the "railroad" fashion 2 apartments per floor. The fire escapes are usually located in the rear. The ever dangerous exception is fire escapes in the front of the building. Who is of concern?
The absence of rear fire escapes is of major concern for the safety of the operating forces
The stairway to the cellar in an OLT is located where?
Inside the building usually beneath the interior stair
New Law Tenements were built after 4/12/1901 they are 85' deep and have 5-6 apts per floor. Where is the entrance to the cellar?
The entrance to the cellar is by way of exterior stairs. The 1st floor cellar ceiling is of fireproof construction and unpierced.
"Newer" New law tenements were constructed between 1916 and 1929 they had much larger floor area and have very large undivided cocklofts. Where would you ind the entrance to the BASEMENT?
The entrance to the basement is by a side or rear door at that level via an exterior stair from the first floor, or through a passageway located in the front of the building
After 4/18/1929 Tenements changed their name to Apartment houses. Between 1930-1940 firewalls were required to be carried to the UNDERSIDE of the roof boards. After 1940 they had to go to the TOP of the roof boards. Why was this done?
To reduce the size of the cockloft and limit fire spread.
Fire escapes in theses Newer NLT's are still common. TRUE or FALSE
True and these buildings have hallways hundreds of feet long
Fireproof class "A" MD's are 4-40 stories or higher. They are well constructed and life hazard outside the fire apartment is not severe. What type of stairs will GENERALLY be found in these buildings?
Apartments may be served by 2 fireproof stairways opening directly into the apartment, or more GENERALLY by 2 fireproof stairways reached by public hallway.
What year did they start building "H" type's?
1916, 1920's-1930' "H" type most popular
What year did they require most OLT's to fire retard stair enclosures?
In most cases, the first line in a OLT is stretched via the interior stairs to the location of the fire. The purpose is to protect the primary means of egress for evacuating occupants and to confine and extinguish the fire. What is the exception?
Flames issuing from a window endangering people on the fire escapes. The first line may be operated from the street to protect people on the fire escape.
Who should chock the door at a fire in a OLT?
The first MEMBER entering the building should use a chock or rug or other means of preventing the door from locking.
Tower ladders and aerial ladders should not be tied up stretching lines up them. TRUE OR FALSE
Hose lines should not be operated into VENTILATION holes from the roof as this decreases ventilation and nullifies the action of lines operating on the top floor. What are the 3 operations a line on the roof should be used for?
Prevent fire from extending past a trench
Extinguish fire that cannot from below, such as fire in a cornice
A member should ALWAYS be posted in the yard or street below to prevent injuries to anyone from falling material. No material shall be thrown where?
Onto roofs of building setbacks and
into NARROW shafts
Gas meters in OLT's are usually found in cellars. Where else may they be found?
Apartments and public hallways!
As a general rule outside streams should not be directed into occupied buildings. OCCUPANTS should be removed first. However, in some cases, life safety or fire conditions may require that outside streams be used in occupied buildings. What are they?
Protect people of fire escapes
Heavy fire in a store
Only the IC can order the use of outside streams This may be the officer arriving 1st!
The use of outside streams can cause injuries to members operating inside a building. MEMBERS inside the building must be warned, and moved to a safe location before outside streams are directed into the building. This location must be verified by the IC...How?
By radio or personal contact by the IC
Engine companies can extinguish a great deal of fir operating across a shaft. However, this should only be done with the permission of?
The IC as it may drive the fire at members advancing from the interior (I thought you cant push fire! on SAT you can!)
The 1st line at a cellar fire in an OLT should remain at the top of the stairs and extinguish any fire that is extending unless?
The fire is minor
A store fire in an OLT may involve a large amount of combustible material. A 2 1/2" line should be stretched and a second line stretched where?
To the entrance hallway. If not needed it may be advanced to the floor above.
This 1st floor public hall MUST be examined immediately
A charged hose line MUST be ready before the store is ventilated
Cockloft fires on OLT's are much smaller than in NLT;s and are therefore not much of a problem. Usually these fires are extinguished via?
From below AFTER an adequate vent hole is cut over the fire
A hoseline should be stretched to the nearest point from which water can be directed onto fire in the shaft. For fires in rooms in the vicinity of a shaft, after the fire has been______, the line should be operated up the shaft to ______ the fire and cool the shaft.
Three indicators of possible collapse in an OLT include?
Plaster ceilings falling
Floors or ceilings sagging
Unusual creaking noises
SRO's require sprinklers in each room and in the stairway. How are they supplied?
City water main
They have no roof tank and CANNOT be supplied by FDNY
Steel in "H" type buildings creates 3 concerns for the fire service what are they?
Steel when heated EXPANDS
Steel when heated may FAIL
TRANSMITS fire and Heat
The most common roof has the top floor ceiling several feet below the main roof beams. TRUE or FALSE
If the pipe is hot to the touch (who touched it? LOL) a top floor examination of the top floor is required. Who is notified of same?
Officer AND IC
(Note: Can no longer touch a soil pipe with the back of an ungloved hand)
Whats our main concern about channel rails utilized in these buildings?
Our main concern is that they are not fire stopped
Instead of stretching around an elevator shaft, it is much easier and faster to use a rope to pull the hose line up to the floor below via the outside of the building, then up the interior stairs to the fire floor. Can you use the stairway window on the fire floor?
No, Floor below
Fire out the windows in the throat, courtyard and front windows? In what order should you extinguish the fire from the TL?
Windows in throat 1st
Then toward the front of the building
Then finally into the front windows
Officer arriving 1st shall transmit info to the IC. It is represented by the acronym LO DANCE...Explain?
Location of fire apartment
Occupants located or accounted for
Difficulties or delays
Access (location of stairs)
Number of Apts
Store fires in NLT's, the 1st 2 lines are stretched into the store and the 3rd line shall go above. The 1st ladder will go into the store and the 2nd ladder above. Areas larger than the store shall be checked due to the possibility of horizontal spread of fire as well as smoke. These buildings have a peculiarity? What is it?
Fire will bypass intermediate areas both veritcally and horizontally
Cellar fires in Class "A" NFP MD's built after 4/12/1901 are no big deal the cellar ceilings are made of concrete and have a two hr fire resistance. How should the 1st line be stretched to extinguish the fire?
By way of the usually numerous exterior approaches to seat of the fire and extinguish.
ALWAYS be aware of the possible civilian life hazard in these cellar areas. TRUE OR FALSE
Top floor fires ALWAYS present the possibility of fire extending into the cockloft. The IC shall designate a company officer as the roof sector supervisor until a chief officer can be assigned. How many saws should be in operation when he arrives?
