Respirator Cleaning

Cleaning - for Single Users

Equipment
  • 2 buckets
  • Warm water
  • Thermometer
  • Alcohol-free wipes and/or soft brush and sponge
  • Neutral detergent - no lanolins or oils (most dish detergents work)
Procedure
  • Prepare 2 buckets (2 gal/7.5 L) of fresh warm but not hot water, follow sequence of use as described below.
  • Disassemble respirator, removing cartridges and/or filters, head harness (if possible) and eye lens outserts.  Do not remove the valves because they are easy to lose.
  • Bucket 1. Clean respirator and associated parts (excluding cartridges and/or filters) with alcohol free wipes, or by immersing in a warm water cleaning solution, scrubbing with a soft brush or sponge.  Use a neutral detergent cleaning solution that does not contain lanolin or oils.
  • Bucket 2.  Rinse in fresh, warm water.  Running water is better than immersion if available.  Thorough rinsing is important to keep detergents or disinfectants from drying on the respirator. [See OSHA 29CFR1910.134, Appendix B-2, running water for rinsing (if available) is preferred over immersion].
  • Allow the respirator to air dry in a non-contaminated environment.  Do not dry with heaters or in sunlight.  Respirators can be reassembled before and after drying.
  • Prior to re-use, conduct checks as recommended by the manufacturer's manual to assure that the system is ready to be placed in operation.  It is very important to check that the inhalation and exhalation valves are in place prior to use.
