The N95 is the most well-liked series of particulate respirator masks that meet United States government standards. The face masks are tested to reduce exposure to airborne contaminates by NIOSH — the National Institiute for Occupational Safety and Health. NIOSH has 9 total approval courses, N95, N99, N100, R95, R99, R100, P95, P99, P100 organized by oil compatibility and filter efficiency.
The letter signifies how the filter tests in environments exposed to grease aerosols:
N95, N99, & N100. These filters are not to be used with oil aerosols. These should be utilized in environments uncovered to particulates which do not contain oil. In many cases, the n- respirators may be reused multiple times.
R95, R99, & R100. These filters are oil resistant. The r- respirators can be used in atmospheres containing particulates any stable or liquid hazard together with oil-primarily based hazards. These are one-time use masks.
P95, P99, & P100. These filters are oil proof. These respirators can be used in any setting uncovered to hazardous particulates. The p- respirators are subject to time of use limitations.
The filter efficiency number refers back to the percentage of airborne particulates that had been removed in testing: ninety five%, 99%, and a hundred%. If a mask is NIOSH approved then it will have a stamp of approval class printed on the respirator.
NIOSH approved masks also come in different sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or different particulate respirator mask, follow these easy steps:
1. Press the mask (respirator ) firmly towards the face with the outside nosepiece on the bridge of your nose.
2. Stretch and position the top headband on the back of your head above your ears. Stretch the bottom headband over the head and position under your ears.
3. With both fingers, mold the metal nosepiece to the form of your nose.
4. To test fit, cup each palms over the respirator and exhale vigorously. If air flows around your nose, tighten the nosepiece: if air flows around the edges of the respirator, reposition the headbands to fit higher and test again until there isn’t a air leakage.
Earlier than selecting the best mask, it is also instructed that you simply speak with experienced industrial safety personnel about an evaluation of your particular environment.
