Mitsubishi i-MiEV - Case 6 Vehicle Fire

19
Vehicle fire
In case of vehicle fire, alert the fire department immediately and start extinguishing the fire using the
following procedures where possible.
WARNING:
Failure to follow these instructions may result in serious injury such as electric shock:
 The Main drive lithium-ion battery is designed to prevent a substantial amount of electrolyte
from leaking from the battery case even in the event of rupture.
 The Main drive lithium-ion battery uses an electrolyte made of flammable “Carbonate ester
solution of lithium salts”, which produces toxic acid vapor when reacting with moisture in the air.
 To handle the electrolyte, wear a mask for organic gas, solvent resistant gloves and eye
protection (safety glasses) to avoid exposure to potentially harmful substances.
1) Fire-extinguishing procedures
WARNING:
Never pour seawater or any water containing salt into the Main drive lithium-ion battery. This can
result in sudden electrolyzing, which generates a large volume of flammable hydrogen gas
① By fire extinguisher
Use a fire extinguisher which is suitable for flammable liquid and electrical equipment fires.
② By water
A large volume of water, such as from a fire hydrant must be used. Make sure to use water
not containing salt, such as tap water, well water or pond water.
DO NOT attempt to extinguish the fire with a small amount of water. If a small amount of
water contacts the inner portion of the Main drive lithium-ion battery, a short circuit can occur
causing the release of toxic gas.
Unless a large volume of salt-free water is available, remain a safe distance from the vehicle
fire and wait for fire department to arrive.
2) Procedures after the fire is extinguished
The Main drive lithium-ion battery must always be discharged (de-energized) after the vehicle fire
is extinguished. Follow the instructions in Case 7: “The Main drive lithium-ion battery is
severely damaged” to discharge the Main drive lithium-ion battery.
WARNING:
The following may remain an issue until the Main drive lithium-ion battery is properly discharged.
 There is a potential for delayed ignition or re-ignition of the Main drive lithium-ion battery even
after it is believed to be extinguished.
 If you detect leaking fluids, sparks, smoke, flames, increased temperature, gurgling, popping
or hissing noises from the high voltage battery compartment, notify the Fire Department.
Ensure area is clear around the vehicle. If possible, open windows to avoid potential gas
build-up.
