Remove inflammable gases,
vapours and liquids from the vicinity
of fuel cells and electrolyzers. The

Hydrogen and oxygen
may escape from the
system. To prevent the
gases collecting and
forming explosive mixtures only use
the system in well-ventilated rooms.
z

in a display case, which is
sufficiently ventilated at all times.
The operator is obliged to prove
this by means of appropriate
measurements.
z
Remove from the vicinity of
the system anything that
could ignite the hydrogen
(naked flame, materials that can
become charged with static
electricity, substances with a
catalytic action).
z
Remove from the vicinity of the
system all substances that could
spontaneously ignite with increased
oxygen concentration.
z
Do not smoke.
z
Hoses, plugs and tanks are
used for pressure compensation.
They must not be fixed or secured
