3-29 Electric Vehicle Fires Flashcards
What is the primary purpose of the Standard Operating Guideline (SOG) regarding Electric Vehicle (EV) Fires?
A) To outline procedures for handling motor vehicle collisions.
B) To provide guidelines for personnel when confronting stranded energy situations.
C) To offer operational tactics for mitigating emergencies related to EV fires.
D) To define the responsibilities of the Division Administrator in EV fire situations.
C) To offer operational tactics for mitigating emergencies related to EV fires.
According to the guideline, how should the apparatus be positioned upon arrival at the scene of a burning vehicle?
A) At least 5 meters away from the burning vehicle.
B) At least 15 meters away from the burning vehicle.
C) As close as possible to the burning vehicle.
D) Adjacent to the high voltage battery pack.
B) At least 15 meters away from the burning vehicle.
What should the officer do during the 360-degree size up, according to the guideline?
A) Request additional firefighting personnel.
B) Identify the type of vehicle and any additional hazards.
C) Begin suppression efforts immediately.
D) Call for a tow truck.
B) Identify the type of vehicle and any additional hazards.
large amounts of water are required for EV fires, according to the guideline so you need
A) To cool down the internal combustion engine (ICE).
B) To create a barrier between the burning vehicle and other structures.
C) To ensure an adequate and continuous water supply for firefighting efforts.
D) To wash away stranded energy from the scene.
C) To ensure an adequate and continuous water supply for firefighting efforts.
What precaution is advised regarding damaged Li-ion HV batteries after the fire has been suppressed?
A) Tow operators should store EVs with damaged batteries at least 5 meters from any structures.
B) Tow operators should store EVs with damaged batteries at least 10 meters from any structures.
C) Tow operators should store EVs with damaged batteries at least 15 meters from any structures.
D) Damaged Li-ion HV batteries should be left on-site for further investigation.
C) Tow operators should store EVs with damaged batteries at least 15 meters from any structures.
What is stranded energy?
the energy remaining in the cell
What is thermal runaway
A process that is accelerated by increased temp in turn releasing further increases temp.
What PPE must be worn?
Full FF PPE and SCBA the whole incident because it’s so toxic
Where do you direct the water stream to in an EV fire?
High voltage battery pack
How long do you assess the battery temperature for after loss stopped?
30 minutes
Thermal runaway can cause the battery to re-ignite as much as how many hours after loss stopped?
48 hours
