6.3.1 Leak Check
In order to check the full face mask-to-face tightness a leak check must be performed before each
use.
(1) Seal the inlet (component housing) with the palm of your
hand or by attaching the non-pressurized regulator.
(2) Check tightness.
(3) Inhale and hold breath for a few seconds.
The mask must stay collapsed on face.
(4) Exhale.
The exhalation valve should open and release the pressure
inside the mask.
(5) If necessary retighten the straps.
a) If the leak check fails, re-don the mask.
If the leak check still fails, the mask must not be used.
