Cleaning and Storage
Cleaning is recommended after each use.
Do not clean respirator with solvents. Cleaning with solvents may degrade some respirator components and reduce respirator effectiveness.
Inspect all respirator components before each use to ensure proper operating condition. Failure to do so may result in sickness or death.
1. Remove cartridges, filters and/or breathing tubes. The center adapter, lens and faceseal can also be removed if necessary.
2. Clean facepiece (excluding filters and cartridges), by immersing in warm cleaning solution, water temperature not to exceed 120°F (49°C), and
scrub with soft brush until clean. Add neutral detergent if necessary. Do not use cleaners containing lanolin or other oils.
3. Disinfect facepiece by soaking in a solution of quaternary ammonia disinfectant or sodium hypochloride (1oz. [30ML] household bleach in 2
gallons [7.5L] of water), or other disinfectant.
4. Rinse in fresh, warm water and air dry in non-contaminated atmosphere.
5. Respirator components must be inspected prior to each use. A respirator with any damaged or deteriorated components should be repaired or
discarded.
6. The cleaned respirator should be stored away from contaminated areas when not in use.
