TB 164 - Transitional Attack Flashcards
(21 cards)
The trademark of the LAFD is our ability to make a what on the seat of the fire uninvolved to involved with coordinated vertical ventilation?
Aggressive interior fire attack
What 3 changes has caused the LAFD to assess modern research to drive changes in our firefighting tactics when appropriate?
Changes in building construction, fuel types, and knowledge of fire behavior
What tactical change has been developed due to scientific evidence?
Transitional attack option
Transitional fire attack has received support from what 3 organizations?
UL, ATF, and NIST
What is the coordinated application of water with a straight stream from the exterior of a structure that provides a brief break of the fire triangle by cooling the environment prior to transitioning into offensive attack?
Transitional attack
What are2 other terms associated with the practice of transitional attack?
“Softening the target” and “hitting it hard from the yard”
2 terms used in the past by the LAFD have been what for transitional attack?
“Taking the heat out of it” and “taking the punch out of it”
What is an exterior application of water using a hand line with a straight stream, as soon as possible to reduce heat prior to firefighters entering the structure?
Transitional attack
The UL, ATF, NIST, studies show that water applied through what exhausting fire or high velocity smoke can have a positive impact in interior conditions reducing temperatures improving survivability of civilians and increasing firefighter safety?
Window or door
Transitional attack is simply an additional tactical option for who to consider when resources and fire conditions warrant it?
First arriving officers
What are indications for use of transitional attack?
Fire conditions at the point of access make it unsafe to enter
Entry is delayed by forcible entry challenges
Ventilation is delayed or non-existent
Water supply is delayed or insufficient
Excessive storage or packrat conditions
Can LAFD members be inside the structure during time of transitional attack?
Shall not
Water should only be applied into what that have fire showing or volatile smoke indicative of imminent flashover?
Windows or doors
Should you try transitional attack if window pane is still intact?
No
Transitional streams shall only flow water until what?
A change in conditions are seen (bulk of the fire knocked down)
To use transitional attack effectively direct a what though an open window or door at an exaggerated angle towards the ceiling of the involved room?
Straight stream
The application of a straight stream angled at the ceiling is similar to what this cooling the upper atmosphere?
Fire sprinkler
Can you use a fog pattern or swirling motion when employing transitional attack?
No
A fog pattern could do what 2 things if employed during transitional attack?
Would cover entire opening and not allow steam/smoke to exhaust
Would rapidly create additional steam and throughly disrupt the thermal balance
Excessive water will unnecessarily increase generation of what for transitional attack?
Steam
If transitional attack is going to be used, you must communicate your intent on the tac channel to who prior to employing this tactic?
All companies
