Ladders 3 Flashcards
T/F all horizontal ventilation tactics whether ventilation for extinguishment or ventilation for search, require communication with, and coordination by, the ladder company officer operating inside the fire area to be vented?
True
What are the stages of modern content fire behavior?
Incipient
Ventilation limited
Early decay
A more rapid and intense 2nd growth if additional oxygen is admitted
Ventilation induced flashover transitioning to fully developed
What is a known life hazard?
A victim can be seen by the rescuer
A victim can be heard by the rescuer
A member has information from a credible source or person at the scene indicating the location of the life hazard
In all incidents of such individual action, the IC (can be an officer) shall forward a report detailing the full particulars to the chief of operations.
What is the 1st roof FFs tactic when he arrives on the roof?

Door control on the fire FLOOR or
A CHARGED hose line is advancing into the fire APARTMENT (not building)
He shall perform vertical ventilation unless addressing a known life hazard then reach in and probe the immediate area of the bullhead if TENABLE
What does the roof FF do if the officer does not want roof FF to perform vertical vent?
Roof FF forces bulkhead door, reaches in and probes immediate area, then immediately closes and controls door
TL first to arrive- NO FRONT FIRE ESCAPE
LCC- where is he
OV- where is he
Officer may request what FF to perform outside vent?
LCC- Pedestal
OV- basket FF
Officer may request roof ff to perform outside vent from fire escape AFTER preliminary roof vent. Only roof ff can perform venting not a member from the inside.
When venting for extinguishment the OV must hear what radio transmissions?
Start water, followed by engine is applying water to the fire and then still request and receive approval from the ladder officer and this only means the vent can take place in the immediate fire area

Yes, this means both standard and known life hazard entry, the officer may disapprove a search entry to limit negative impact of ventilation
When venting for search what is the priority order?
Clear out the window
Reassess the conditions
Reach in and probe the immediate area
