In the event your FCEV catches fire with the power system OFF, the
power source of the high-voltage system is cut off, so you are unlikely
to get shocked while you put out the fire using water. (Even when the
vehicle is submerged in water, there is no risk of getting shocked.)
However, if your car catches fire with the ignition ON, you MUST use
the fire extinguisher. Any attempt to extinguish the fire with water may
cause electric shock.
It is recommended that you use a dedicated fire extinguisher (CO2)
for an electrical fire of the high-voltage system.
The hydrogen tank passed a high temperature test and is deemed
safe, so it is unlikely to explode.
In case of vehicle fire, a heat-sensitive safety valve is activated to
exhaust the hydrogen gas downward from the tank by force.
Therefore, the hydrogen tank is unlikely to explode. However, addi-
tional flames can flare up from the forced exhaustion of the gas, so
please evacuate to a safe place far away from the vehicle.
