good operating condition. Any damaged or defective parts must be
replaced before use. The following inspection procedure is suggested:
Check the facepiece for cracks, tears and dirt. Be certain the
facepiece, especially the face seal area, is not distorted.
The material must be pliable - not stiff.

Examine the inhalation valves for signs of distortion, cracking or
tearing. Lift valves and inspect valve seal for dirt or cracking.
Ensure that the head straps are intact and have good elasticity.
Examine all plastic parts for signs of cracking or fatigue; make sure
the gaskets are properly seated.
Remove the exhalation valve cover and examine the exhalation valve
and valve seat for signs of dirt, distortion, cracking or tearing. Replace
the exhalation valve cover.
The lens should be clean and free from any cracking or fatigue.
Test by tapping with hard object (such as a closed fist), to check for
embrittlement.
