personal injury or death.

PREPARATIONS FOR USE

The following inspection points must be checked before donning the respirator. A respirator that
fails the inspection must not be used. The respirator must be repaired or replaced.
1. Head harness strap and clips: Check to see that the strap still has elasticity. Inspect for
breaks or tears and make sure all adjusters are in place and working properly. Check that the
clips are not distorted and that the door clips provide tension on the strap.
2. Facepiece: Check facepiece for dirt, cracks, tears, or holes. Inspect the shape of the
facepiece for possible distortion that may occur from improper storage and make sure the
rubber is flexible, not stiff. Also, check the yoke for cracks.
3. Inhalation and exhalation valves: Check for cracks, tears, distortion, dirt, build-up of material
between valve and valve seat.
4. Cartridge bayonet connectors: Check to make sure connectors are in place and check for
cracks and damage.

cracks, or other damage, particularly the sealing bead around the bottom.
