The N95 is the preferred sequence 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 for use with oil aerosols. These ought to be utilized in environments exposed to particulates which don’t contain oil. In many cases, the n- respirators might be reused multiple times.
R95, R99, & R100. These filters are oil resistant. The r- respirators can be utilized 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 utilized in any environment uncovered to hazardous particulates. The p- respirators are topic to time of use limitations.
The filter effectivity number refers to the proportion of airborne particulates that have been removed in testing: 95%, 99%, and 100%. If a mask is NIOSH approved then it is going to have a stamp of approval class printed on the respirator.
NIOSH approved masks also come in several sizes, and a well fitting mask is vitally important. When test-fitting an N95 masks or different particulate respirator masks, observe these simple steps:
1. Press the mask (respirator ) firmly towards the face with the outside nosepiece on the bridge of your nose.
2. Stretch and place 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 both 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.
Before choosing the proper mask, it is also urged that you simply converse with skilled industrial safety personnel about an evaluation of your particular environment.
