Donning the Facepiece
Before donning the facepiece, examine it to verify that it is complete and in serviceable condition.
• Verify that the inhalation valves in the nose cup are properly installed.

page 9) and properly positioned in the facepiece.

which could affect the fit of the facepiece. Refer to the appropriate steps in Appendix G: Facepiece Fitting” on
page 59.
