Before You Begin
Below is a summary of the requirements and recommendations for operational inspections of respirators:
• Inspect the respirator before each use and after each cleaning. (Clean the respirator after each use. See
“Chapter 3: Cleaning & Storing the Respirator” on page 41.)
• Inspect respirators for emergency use as frequently as required to ensure the respirator will function properly.
The Occupational Safety and Health Administration (OSHA) of the U.S. Department of Labor requires at least
monthly inspection of respirators for emergency use (29 CFR 1910.134).
• The National Institute for Occupational Safety and Health (NIOSH) recommends an inspection for cylinder
pressure at least weekly.
Storage conditions at your location or the regulations that apply to your respiratory protection program may require
more frequent periodic inspections.
WARNING
Follow the regular operational inspection procedures exactly as written. If the respirator does not operate as
described or if any other operational malfunction is noted, do not use the respirator. Remove it from service
and tag it for repair by authorized personnel. Failure to properly inspect the respirator may result in serious
injury or death.
