What is essential to ensure FF safety?
Tactical
maneuver or agility is essential to ensure firefighter safety.
Interface
There is a clear line of demarcation between the structures and the wildland fuels
Intermix
a condition where structures are scattered throughout a wildland area:
Is interface or intermix more difficult to triage? Why?
Intermix is more complex, usually requires a higher ratio of engines to structures
What separates a safety zone from a TRA?
TRAs are temporary when egress to a safety zone is compromised
what are the 3 major structure triage categories?
non-threatened
threatened defensible
threatened non-defensible
how is a non-threatened structure defined?
SZ & TRA are established, and structure is unlikey to ignite during fire front
how is a threatened defensible structure defined?
SZ & TRA are present, but require FF to implement defense tactics w/fire front
how is a threatened non-defensible structure defined
no SZ or TRA & unsafe to protect during fire front contact
what is the greatest challenge to FFs when determining to defend a structure?
Making an accurate fire behavior forecast in advance of the fires arrival
what are the 7 structure defense tactical actions?
what structure triage category does “check and go” follow under?
threatened non-defensible
what is check and go?
rapid evaluation to check for occupants requiring removal or rescue
what is prep and go?
do what you can to prepare a home and then leave prior to the fire front
what is prep and defend?
+SZ or TRA, with time to prepare for defense
what is fire front following?
a follow-up tactic, search for vics, put out spots, start perimeter control
what is the goal of fire front following?
search for victims, extinguish spot fires, reduce ember production
what is bump and run?
moving ahead in the spotting zone, put out spots and defend as much as possible
is bump and run offensive or defensive?
both!
defensive when there aren’t enough resources
offensive when steering the fire to a desireable end point.
why is bump and run so dangerous?
its a frontal attack and places resources in front of the fire front
what is anchor and hold?
using large water streams from fixed supplies to stop the fire
where is anchor and hold most effective?
in urban neighborhoods where fire goes from house to house
what is tactical patrol?
coming in after the fire front has passed
what is the risk management process? (5)
situational awareness
hazard assessment
hazard control
decision point
evaluate
