Negative Pressure Leak Test
In order to check the facepiece-to-face tightness a negative pressure leak test must be performed
before each use.

The facepiece must stay collapsed on face.

The exhalation valve should open and release the pressure
inside the facepiece.
(3) If necessary retighten the straps.
If the leak test fails the facepiece must not be used.
