BC ALARMS Flashcards
NPF MD 3.2.12
In some cases, the second or third lines may be urgently needed in one of the exposures. The decision as to the location to which these lines shall be stretched rests with the Incident Commander and is based on his/her size- up of the fire situation. For example, at a fire in an Old Law Tenement it is often necessary to stretch the second line or the third line into Exposure 2 or 4 because fire has extended or is about to extend across the narrow shaft or shafts between buildings.
3.4.4 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.
For a fire in an Old Law or New Law Tenement, special call an extra engine and truck for fire on two floors. If progress is not made on at least one floor in a short period of time, transmit a 2nd alarm. If fire is in a shaft extending into an exposure, transmit a 2nd alarm. If fire is extending into two exposures, transmit a 3rd alarm
OLT FIRE
4.1.3 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.
OLT FIRE
4.1.5 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.
Cellar Fires OLT
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. This line should remain at this position to provide protection for people coming down the stairway, and to extinguish fire which may be extending upwards from the cellar via partitions, dumbwaiter shafts and other voids. 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.
Stairway Fires
A. Fires in stairways in OLT’s present a serious situation since the stairway is the primary means of egress for the occupants. If the fire extended into the stairway from an apartment, it is possible that the fire escape exit may also be cut off by flame from the apartment windows.
B. The first hoseline should be stretched up the stairway, operated to extinguish fire, shut down and advanced further up the stairway. When possible, the line should be operated up the wellhole to cool off the hall and stairs above. This procedure should be repeated until line is advanced to the top floor. A second line should follow to finish up extinguishing operations and to serve as protection for members advancing the first line. Apartments must be checked for possible extension of fire in them.
party wall balconies OLT
The roof firefighter must inform his/her officer and the Incident Commander of the fire of the presence of party wall balconies in the rear of the building. The Incident Commander should consider calling an additional ladder company to aid in rescue and search via the rear party wall balcony. A line may have to be stretched to the rear to protect the occupants and firefighters on the balconies. Portable ladders may also have to be brought to the rear.
NFP H TYPE
Additional units: 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. When additional units have been special called, they should be given instructions by radio regarding positions, masks, extra hooks, etc. 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.
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. These additional battalion chiefs could be assigned as top floor sector supervisor, roof sector supervisor, or as needed.
The officer who arrives first on the fire floor shall transmit the following information to the Incident Commander:
a. Location of the fire apartment: (Wing, Floor, Apartment No.)
b. Number of apartments on the floor of the fire wing.
c. Fire conditions: (Fire out in public hall, heavy smoke condition)
d. Access: Location of stairway in fire wing closest to fire apartment. Report if it is possible to go from one wing to another above the first floor. (Transverse, wing or isolated stairs)
e. Fire extension: Whether fire is extending and how it is extending. Need and location for additional lines. (Fire floor or floor above adjacent apartment). Give reasons.
f. Difficulties or delays in gaining entrance to fire apartment or in advancing line. Give reasons.
g. Occupants: If occupants have been located and are accounted for. (This information may be obtained from one of the occupants or from a neighbor).

b. Fire showing out windows (number and location) which are not visible from the street and whether any exposure is affected.
c. Color and volume of smoke coming from windows.
d. Persons trapped and their exact location.
e. Location of stairways and fire escapes.
f. If the building fronts on more than one street. Whether there is access for apparatus. Whether it is a street, alleyway, parking lot, vacant lot, etc.
g. Whether there is any difference in the height of the building from street to street, or from front or rear, or from side to side. (Figure 16)
h. Evidence of unusual heat, smoke or fire in the cockloft, if fire has burned through roof. Need for additional saws.
i. Location of parapet and dividing walls.

top fl fire NFP H type
5.3.3 Top Floor, Roof and Cockloft Fires
A. Top floor fires always present the possibility of fire extending into the cockloft. This can result in a complete loss of the top floor and roof. Fire can also drop down to the lower floors. It is imperative for the IC to assign a roof sector supervisor early into the operation. The IC shall designate a company officer as the roof supervisor until a chief officer can be assigned. Once a sector supervisor is assigned all communications between the roof and the IC shall go though that roof sector supervisor.
If any hot spots are found that require examination, small holes can be made for visual check. Should any fire be encountered, notify Incident Commander and immediately go to the top floor and check the termination point of this void for any extension to the cockloft area. If fire is found here a line must be provided at that point and the roof opened above.
NFP H type
5.4.3 Consider a special call for the Satellite unit and its manifold. It could be placed in front of the fire building or within the courtyard. Engine companies arriving after the manifold is set up should be informed by Incident Commander as to the size and number of lengths of hose to bring to the manifold for stretching to their point of operations.
FPMD
These fires require a coordinated effort from the designated attack stairway with 21⁄2” hose. All extinguishment efforts shall proceed initially from the one attack stairway. If a second stairwell is required for attack and extinguishment, it should not be the stairwell designated as the evacuation stair. The IC shall notify the borough dispatcher as well as all members operating on scene, the letter designation of the stairwell being used for attack operations.
HVAC: The systems and their components of duct work and shafts can contribute to smoke infiltration to other areas of the building. An IC should confirm that all HVAC systems are shut down prior to commencing any fire operations. They are installed most commonly in hotels and the hallways of up scale high rise apartment buildings.
Ventilation procedures in HRFPMDs vary greatly from the procedures we use for non-fireproof multiple dwellings. Like high rise office building procedures, ventilation of the fire apartment in HRFPMDs should take place after the main body of fire has been controlled. The IC shall control all ventilation other than the fire apartment.
Signal 10-77 Notification of a Fire in a High Rise Fire Proof Multiple Dwelling. Note: High Rise Building includes all buildings 75 feet or more in height. 4 - Engine Companies 1 - High Rise Nozzle Engine Company IF none of the initial 4 Engine companies have a HRN. 4 - Ladder Companies 1 - Ventilation Support Unit 3 - Battalion Chiefs 1 - Deputy Chief 1 - Rescue Company 1 - Squad Company 1 - FAST Unit 1 - CFR-D Engine Company Field Communications Unit Rescue Operations Battalion Safety Battalion Safety Officer (the 4th due Battalion Chief for the alarm box assignment)
The 10-77 signal should provide sufficient units to initially manage a medium fire and smoke condition in a HRFPMD.
Some Examples:
Wind impacted fire conditions.
Advanced fire on arrival.
Heavy smoke on numerous floors.
Numerous reports of persons in difficulty due to smoke.
B. The 10-77 signal will be given at all HRFPMD where fire is visible from the exterior on arrival, or other factors indicate the need for the 10-77 assigned units, such as wind impacted conditions.
When the second alarm is transmitted for a fire in a HRFPMD prior to the transmission of a 10-77 the IC will receive the balance of the 10-77 assignment in addition to the second alarm assignment.
6.1.7 The FAST Unit and CFR Engine shall be assigned to the Fire Sector when the fire is above the sixth floor. They can be staged on the floor below the fire floor, ready for rapid deployment. At lower floor fires (sixth floor or below) the position of the FAST Unit and the CFR Engine will be determined by the Incident Commander. The FAST Unit should carry a set of elevator keys.
FPMD
Increased stack effect caused by the opening of the attack stairway lobby and bulkhead doors. The bulkhead door shall be vented upon the direction of the Incident Commander after the main body of fire has been controlled.
Note: The stretching and operation of two hand lines at a 10-77 MAY REQUIRE transmission of additional alarms.
FPMD
ROOF 1 st due
Control Vertical Ventilation:
Members assigned to roof operations must remain at the roof level to ensure that bulkhead doors remain closed until the IC orders them vented. These members will be in position to assist the ventilation support group with stairwell pressurization and sequential ventilation.
When conditions are encountered such as broken bulkhead windows, doors missing or incapable of being closed, the IC and units operating in the fire sector shall be notified. This open bulkhead door will cause the movement of smoke and heat to that stairwell and will also diminish the effectiveness of any stairwell pressurization activity that may have been initiated.
6th due ladder on 10-77 is ventiliation support grp
The priority order for the use of PPV fans will be:
Pressurizing the attack stairwell to support the fire attack, by controlling the smoke condition at the attack stair doorway and throughout the attack stairway.
Pressurizing the evacuation stairwell for smoke and CO control.
Ventilating the public hallways for smoke and CO control.
The ventilation support group will inform the Incident Commander of the recommended placement of the PPV fans based on:
The number of PPV fans and personnel available
The location of the fire floor
The number of floors in the building
The stage of firefighting operations
FPMD
- At operations requiring the resources of 10-75 or greater, all Chiefs, including the Safety and Rescue Operating Battalions, shall report in with their Post Radios and their aides in full PPE.
Ensure the Post Radio is given to the 2nd to arrive engine officer, so that they can establish a communications link on the Command Channel between the fire sector and the IC if necessary.
If the 2nd BC has not arrived, the IC may have to use the 40 watt UHF vehicle radio to communicate with the 2nd engine officer on the Command Channel.
In an emergency, Post Radios can provide 45 watt communication on the tactical channel.
Announce the attack stair designation on handie-talkie and/or the Post Radio when required. The borough dispatcher shall also be advised of the attack stair letter designation so that they can announce it to all incoming units.
A “no flow” registered on the flow meter indicates a valve is closed in the system (riser control valve). A “high flow” reading indicates a pipe may have fractured or other outlet valves are open on the riser.
Anytime the siamese is being supplied and an engine officer or the Incident Commander communicates there is not enough water pressure. The ECC supplying the siamese shall communicate to the IC the flow meter reading.
Because of the lower building height of these fireproof buildings and the heavy smoke conditions that usually occur in the attack stairway after the attack has begun, emphasis will generally be placed on venting the attack stair bulkhead after approval of the IC, early in the operation. This is done to relieve conditions in the attack stairway and/or public hallways. When ordered, the venting of the attack stairway in LRFPMDs will be accomplished by the 1st and 2nd arriving Roof firefighter position
