FFP - MULTIPLE DWELLINGS Flashcards
You are a newly assigned LT. working in the Brownsville section of Brooklyn surrounded by dozens of HRFPMDs. Members in the kitchen are discussing some of the prominent variables that affect smoke movement in these types of buildings. They make the following statements. Which choice represents the only correct statement?
A) Smoke and hot fire gases increase the air pressure inside the fire area or fire apartment. This higher pressure will always travel towards areas of lower pressure, creating a flow path for fire travel.
B) Lower pressure areas include public hallways, vertical shafts, stairwells, elevators and other open apartment doors especially on the same side of the fire apartment.
C) All horizontal ventilation inside the fire apartment should be limited and controlled by the ladder company officer operating in the fire apartment and/or the Fire Sector Supervisor.
D - Vertical ventilation will only be performed under the direction of the IC, and/or Fire Sector Supervisor.
ANSWER: A) Smoke and hot fire gases increase the air pressure inside the fire area or fire apartment. This higher pressure will always travel towards areas of lower pressure, creating a flow path for fire travel.
B - Lower pressure areas include public hallways, vertical shafts, stairwells, elevators and other open apartment doors especially on the same OPPOSITE SIDE of the fire apartment.
C - Horizontal ventilation in fire apartment controlled by the LADDER OFFICER ONLY.
D - Vertical ventilation performed under the direction of the INCIDENT COMMANDER ONLY.

(FFP - MDs 6.2.1)
Additional factors that influence smoke, heat and air movement inside HRFPMDs are stack effect, wind and HVAC. Regarding these factors, which of the following is correct?
A) The stack effect is influenced by the height of the building, temperature differential between the upper and lower floors, air leakage to other floors, and the wind.
B) Wind pressures external to the building create pressures within the structure on both the windward side (low pressure) and the leeward side (high pressure) because of leakage through windows, walls or other openings, however small.
C) An IC should confirm that all HVAC systems are shut down prior to commencing any fire operations. They are most commonly installed in hotels and the hallways of upscale high rise apartment buildings.
D) Generally, wind moving across roof level will cause a higher pressure to be created which can increase negative stack inside the stairwell, regardless of which side of the building the wind is impacting or the position of the bulkhead on the roof.
ANSWER: C) An IC should confirm that all HVAC systems are shut down prior to commencing any fire operations. They are most commonly installed in hotels and the hallways of upscale high rise apartment buildings.
A - Stack effect influenced by height of building, TEMPERATURE DIFFERENTIAL BETWEEN THE OUTSIDE AND INSIDE OF THE BUILDING, air leakage to other floors, and the wind.
B - Windward side is HIGH PRESSURE / Leeward side is LOW PRESSURE.
D - Wind moving across roof level will cause a LOWER PRESSURE to be created which can increase POSITIVE STACK inside the stairwell, regardless of which side of the building the wind is impacting or the position of the bulkhead on the roof.
STACK EFFECT INFLUENCED BY “WHAT”
W - WIND
H - HEIGHT OF BUILDING
A - AIR LEAKAGE TO OTHER FLOORS
T - TEMPERATURE DIFF BETWEEN OUTSIDE AND IN
