The FCX does not present any greater hazards than a
conventional gasoline-powered passenger car or any
other type of electric car. It performed well in front-,
offset-frontal-, side-, and rear-impact tests, with no
damage to any of the high-voltage or hydrogen
components.
Flammable Fluid
The only flammable fluid used by the FCX is
transmission oil. The capacity is 1.2 quarts (1.1 liters).
Hydrogen Properties and Potential Hazards
The hydrogen used in the FCX is a nontoxic and
odorless gas. Unlike gasoline and oil, it cannot spill and
it cannot harm humans, wildlife, or the environment.
However, like other fuels, hydrogen is both flammable
and explosive. Compared to gasoline, for example,
when mixed with air, hydrogen has a much higher and
wider range of flammability. Its explosive range is also
much higher and wider, as illustrated in the graph.
To limit the chance of hydrogen leakage, the FCX has
many built-in safety features to help contain hydrogen,
detect a leak, and automatically shut off the flow of gas
if a leak is detected (see pages 5-6).
Since hydrogen is 14 times lighter than air, a leak
occurring in an open area would quickly rise and
dissipate into the atmosphere. In an enclosed space, the
hydrogen would collect in the uppermost areas.
Emergency personnel should also be aware that
hydrogen flames are invisible. Also, hydrogen burns
very quickly and radiates less heat than gasoline or other
fuels.
