The N95 is the most well-liked 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 classes, 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 oil aerosols:
N95, N99, & N100. These filters should not to be used with oil aerosols. These must be utilized in environments exposed 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 utilized in atmospheres containing particulates any strong or liquid hazard together with oil-based hazards. These are one-time use masks.
P95, P99, & P100. These filters are oil proof. These respirators can be used in any surroundings exposed 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: 95%, 99%, and one 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 numerous sizes, and a well fitting masks is vitally important. When test-fitting an N95 masks or different particulate respirator masks, comply with these simple steps:
1. Press the mask (respirator ) firmly against 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 underside headband over the head and position beneath your ears.
3. With each 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 across the edges of the respirator, reposition the headbands to fit better and test again until there isn’t any air leakage.
Earlier than choosing the proper mask, it is also advised that you speak with skilled industrial safety personnel about an evaluation of your specific environment.
