Respirator Cleaning, Storage & Inspection
A respirator only protects if it seals well, the filters work and the parts are in good shape. Dirty, cracked or poorly stored masks can fail without warning. Proper care is part of OSHA's respiratory protection standard.
- Respirator Users
- Supervisors
- Program Administrators
Clean and disinfect
- Clean after each use when the respirator is shared, and as often as needed for personal masks to keep them sanitary (1910.134(h)).
- Remove the cartridges or filters, valves and any parts the maker says to remove.
- Wash the facepiece in warm water (about 110 degrees F or lower) with mild detergent or a manufacturer-approved cleaner. Scrub gently with a soft brush.
- Disinfect if required, using a manufacturer-recommended solution or wipes. Rinse thoroughly to remove soap and disinfectant residue.
- Air dry in a clean place; do not use heat or direct sunlight, which can warp rubber.
- Do not wash filters and cartridges or get them wet (unless made for it).
Inspect every time
- Facepiece: cracks, tears, dirt, distortion, stiffness or sticky rubber
- Straps: cut, stretched or brittle; buckles that work
- Valves: clean, flexible and seated; no cracks or residue
- Filters and cartridges: right type, not damaged, within date, no breathing resistance changes
- Lens (full-face): scratches or cracks that impair vision
- Do a user seal check each time you put it on
- Replace broken parts with the maker's parts only; do not mix brands. Remove damaged respirators from service
Storage
- Store in a sealed bag, container or case that protects against dust, sunlight, heat, cold, moisture and chemicals.
- Do not leave respirators loose in a toolbox, truck bed or on the dashboard.
- Store so the facepiece is not deformed, with the straps relaxed.
- Keep spare masks and cartridges in labeled packaging, with expiry dates visible.
Change cartridges and filters
- Particulate filters: replace when breathing becomes difficult, when dirty or damaged, or when contaminated with oil if non-oil-rated (see Respirator Filters).
- Gas and vapor cartridges: replace on a change schedule based on exposure, not on smell, unless a reliable end-of-service-life indicator is available (1910.134(d)(3)).
- Once opened, cartridges begin absorbing contaminants from the air even if not used; store sealed.
