During use

4.3.1 Ventilation system use
The ventilation system can be closed to prevent rainwater and
fire-extinguishing water from penetrating. Despite the steel
spark protection mesh, Dräger recommends to completely
close the ventilation system during fires, near fires or when
there is a strong wind. If the helmet is used during water
rescue, Dräger recommends to open the ventilation system.
1. Operate the sliding lever on the top of the helmet with one
hand (see figure 36).
Position 1 = Closed
Position 2 = Open

Maintenance intervals

Inspect the helmet before and after each use, paying particular
attention to all the fastening points (harness and retention

conformity of the helmet.
Check that there are no colour changes and/or cracks on

the helmet shell and harness.
Check that there are no cuts and/or breakage at the edges

and the holes.
Check that the suspension system is intact by checking the

seams.
