enriched environment, for escape purposes or by people with facial
hair growth between the skin and face-piece sealing surface such as
stubble, beard growth or sideburns, which cross the respirator surface

provide a seal.
2. Inhale gently
3. The respirator should pull inwards on the face
(vacuum eect).

the harness straps for more secure seal and
repeat check.
