WARNING
3
Since hydrogen gas is highly flammable, a
hydrogen gas leak is extremely dangerous
as the leaked gas, which is dispersed into
the atmosphere, can ignite, resulting in a
fire in which you or someone else can be
serious injured or killed. Keep flammable
materials and liquids away from the vehicle
at all times, especially if a hydrogen gas
leak is detected.
In the case of a hydrogen gas leak, a buzzer
will sound and the hydrogen gas leak
indicator will come on. If you are driving
the vehicle, stop in a safe, well-ventilated
place. Then turn the power mode to OFF
and contact an authorized Honda Clarity
Fuel Cell dealer at once. You should also
display signs warning of the danger and be
aware of and keep away anything that
could ignite the gas.
The system is designed so that in the event
that the vehicle catches fire, the gas inside
the tanks will be released through the tank
valves, thereby ensuring that pressure (due
to heat from the fire) within the tanks does
not build up.
