Multiple Dwellngs Flashcards
If a communication system does exist in a HRFPMD the
1st arriving chief may utilize to direct and control the evacuation of the fire floor and the floors above
Are there building communication systems in HRFPMD’s
Limited or no building communications
A position outside the building by a chief may
Offer a view of the fire conditions
Especially important if wind is a factor
Also may be able to determine the exposed face of the building to the wind
When PPV are being used
Position outside the lobby may provide a better communication capability away from the noise of the fans
If a HRFPMD has a communication system it should be
Entered into the CIDS program
At 10-75 or greater alarms all chiefs shall report in with
Their post radios and their aides in full PPE
Includes the rescue and safety battalions also
Who is the IC
1st BC to arrive
He establishes a locations best suited for the ICP. If this location is not the lobby he shall advice dispatcher to notify all incoming units of the ICP location. The IC must also insure the post radio is given to the 2nd due engine officer. The 2nd due engine officer must establish the communications link on the command channel with the IC
If the 2nd due BC is delayed the IC may have to
Use the 40 watt UHF vehicle radio to communicate with the 2nd due engine on the command channel.
In an emergency what can you do with the post radio to communicate if the 2nd due BC is delayed into the box
Use the post radio on the tactical channel
When the attack stairs are determined what must be done by the IC
Announce the attack stairs on the HT and/or post radio.
The borough dispatcher must also be advised of the stair letter so it can be relayed to the incoming units
If scissor stairs are present what must be done
Ensure proper labeling
Ensure fire floor door is being maintained closed
Make sure all supervisors/sectors are aware
Of the strategy and establish a communications link with all sectors
Where are units staged
In the lobby if there is room. If no room stage the units outside
Elevators must be
Recalled
Searched
Controlled
You can utilize the 3rd and 4th due ECC to
Assist in receiving and recording information from calls of occupants on floors above
2nd due BC is the
Fire sector supervisor
2nd due BC on arrival gives
His post radio to the IC. Before he goes up he must make sure the fire sector has a post radio.
2nd due BC must verify
Attack and evacuation stairs
If scissor stairs make sure they are labeled correctly
2nd due BC must also ensure the
Evacuation stair door remains closed
2nd due BC must also
Relay to IC need for WCD
Supervise fire sector operations
Do not become physically involved
Maintain order and reduce congestion in attack stairs
Control ventilation when needed as ordered by the IC
Insure HRN is in place and ready to operate if needed
Ensure access and resources for 2nd due ladder in apt below for WCD
3rd due BC is the
SAE group supervisor
3rd due BC is responsible for
Search of all floors, stairs and halls above the fire sector
Maintain communications with the fire sector and IC
Ensure post radio is used on the command channel
Request use of PPV fans if needed
Record apartments and floors that have been searched
Can the 2nd hose line be used on the floor above in a HRFPMD
Yes.
Can’t do this in a high rise office building
Can fire walls be depended upon to stop the spread of fire
No
What is the primary purpose of the 1st hose line stretched at a multiple dwelling fire
Safeguard the stairway for use by escaping occupants
In old law tenements floor joists supported by masonry walls are
Generally provided with fire cuts
In a High Rise MD, who is responsible to recall and search all elevators
2nd arriving ladder company and IC
1st arriving ladder just recalls
IC responsible for recall, search and control
The stack effect is influenced by
- Height of building
- Temperature differential between outside and inside
- Air leakage to other floors
- Wind
An IC should confirm all HVAC systems are shut down prior to
Commencing any fire operations
Generally wind moving across a roof level will cause a
Lower pressure to be created which can increase positive stack effect inside the stairwell regardless of which side of the building the wind is impacting or the position of the bulkhead on the roof
Horizontal ventilation of the fire apartment is limited and controlled by the
Ladder officer operating inside the apartment. ALL other ventilation must be strictly limited and controlled by the IC
When a HRFPMD fire is located above the 6th floor (7th floor or higher) where is the FAST unit and the CFRD unit assigned
- Fire Sector
- Staged on the floor below the fire
- FAST unit should carry a set of elevator tools
*If fire on the 6th floor or below the position of these units will be determined by the IC
10-77 will be transmitted for medium fire and smoke conditions in a HRFPMD in the following examples
- Wind impacted fire
- Advanced fire in arrival
- Heavy smoke on numerous floors
- Numerous reports of persons in difficulty due to smoke
When a 2nd alarm is transmitted after a 10-77 signal, which BC assigned on the 2nd alarm is designated as the RUL
1st BC
All Battalions have at least 1 Engine equipped with a
HRN
High Rise Nozzle
4th Engine at a HRFPMD is responsible for placing the
HRN into operation IF this alternate strategy is needed. If the HRN is not needed the 4th assigned Engine will support and assist the 3rd Engine Company’s operation.
If the 4th assigned Engine is not equipped with a HRN, the officer shall
Contact the dispatcher for the identity of the unit carrying the HRN that is already assigned to the box. In this instance the IC shall determine which engine company places the HRN into operation
If the HRN is to be used the 4th engine will put it into operation
They will either use the hose already in place for the 2nd hose line or stretch their own line
What is the height requirement to be considered a Low Rise Fireproof MD
- Less than 75 feet
- Generally 3-7 stories
- Isolated or attached
- Usually no standpipe
- May have elevators
- May have compactors
- May have one or two stairways (open or closed)
- May be built as one building with two separate sections separated by fire doors on each floor
Low Rise Fireproof facts
- The possibility of auto exposure exists and must be address immediately by the IC
- Emphasis placed on venting the attack stairway bulkhead early in the operation. The attack stair bulkhead will not be vented until permission is granted by the IC
- When ordered by the IC the 1st and 2nd roof firefighters will vent the attack stairs
- 2nd due Ladder responsible for all floors and stairs above the fire
- Can use 1 3/4 if every apt door is within 50 feet of every stairwell (CIDS)
Procedures for wind impacted fires at Fireproof MD’s
- When wind impacted fire conditions exist in FPMD, the IC shall notify the Borough Dispatcher so this information can be relayed to all responding units
- When fire or smoke is not venting out an open or failed window the IC must immediately relay this info to all units on the scene
- When fire or smoke is not venting out an open or failed window the IC must communicate with the officers on the fire floor to determine interior conditions
- If the IC determines an alternate strategy for extinguishing the fire should be implemented the IC must communicate this to all Officers and receive acknowledgment to the regular SOP’s
The fire apartment door should not be fully chocked open unitil
The fire is CONTROLLED by the operating hose line
When HT communications are hampered between operating sectors/groups and the ICP consider the following
- Use of Post radios on the Command Channel deployed to each sector/group
- Use of High Rise Repeater if available on the Command Channel
- Set up HT relay on intermediate floors
- Utilize personnel outside the building to relay HT messages
- Moving to a different position in the lobby. EX: walking around in the vicinity of elevators
- Cell phones shall be turned on and carried by Battalion and Division firefighters
- Utilize ANY building communication system if present AND reliable
A 10-77 signal should provide sufficient units to initially manage a medium fire and smoke condition in a HRFPMD with the following characteristics
- Wind impacted fire conditions
- Advanced fire on arrival
- Heavy smoke on numerous floors
- Numerous reports of persons in difficulty due to smoke
If you are the 1st assigned BC on a 2nd alarm for a fire in a HRFPMD you would be assigned to what position
Resource Unit Leader
The FAST unit and CFR Engine shall,be assigned to the Fire Sector when the fire is above the ______ floor in a HRFPMD. They can be staged on the floor below the fire floor ready for rapid deployment. At lower floor fires the position of the FAST unit and CFR engine will be determined by the __________ at a HRFPMD
