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 uncovered to grease aerosols:
N95, N99, & N100. These filters aren’t to be used with oil aerosols. These ought to be used in environments exposed to particulates which don’t comprise oil. In many cases, the n- respirators can be reused a number of times.
R95, R99, & R100. These filters are oil resistant. The r- respirators can be used in atmospheres containing particulates any stable or liquid hazard including oil-based hazards. These are one-time use masks.
P95, P99, & P100. These filters are oil proof. These respirators can be utilized in any surroundings uncovered to hazardous particulates. The p- respirators are subject to time of use limitations.
The filter efficiency number refers to the share of airborne particulates that had been removed in testing: 95%, 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 additionally come in several sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or other particulate respirator mask, follow these straightforward steps:
1. Press the mask (respirator ) firmly against 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 underside headband over the head and position below your ears.
3. With both palms, 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 round your nostril, tighten the nosepiece: if air flows around the edges of the respirator, reposition the headbands to fit better and test once more until there isn’t any air leakage.
Earlier than choosing the proper mask, it can also be recommended that you just speak with skilled industrial safety personnel about an evaluation of your particular environment.
