N95 Respirator Mask Types: Fundamental Information

The N95 is the preferred series of particulate respirator masks that meet United States authorities standards. The face masks are tested to reduce publicity 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 for use with oil aerosols. These should be utilized in environments exposed to particulates which don’t include oil. In lots of cases, the n- respirators will be reused multiple times.

R95, R99, & R100. These filters are oil resistant. The r- respirators can be utilized in atmospheres containing particulates any solid or liquid hazard including 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 effectivity number refers back to the proportion of airborne particulates that had been removed in testing: 95%, 99%, and one hundred%. If a masks is NIOSH approved then it should have a stamp of approval class printed on the respirator.

NIOSH approved masks additionally come in different sizes, and a well fitting mask is vitally important. When test-fitting an N95 masks or other particulate respirator masks, follow these simple steps:

1. Press the masks (respirator ) firmly in opposition to the face with the outside nosepiece on the bridge of your nose.

2. Stretch and position the highest headband on the back of your head above your ears. Stretch the bottom headband over the head and place below your ears.

3. With each palms, mold the metal nosepiece to the shape of your nose.

4. To test match, 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 again till there is no such thing as a air leakage.

Earlier than selecting the best mask, it is usually prompt that you just communicate with skilled industrial safety personnel about an evaluation of your explicit environment.
