N95 Respirator Mask Types: Primary Data

The N95 is the most popular 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 nine 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 uncovered to oil aerosols:

N95, N99, & N100. These filters are not for use with oil aerosols. These should be used in environments uncovered to particulates which don't include oil. In many cases, the n- respirators could 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 including 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 surroundings uncovered to hazardous particulates. The p- respirators are subject to time of use limitations.

The filter efficiency number refers to the proportion of airborne particulates that were removed in testing: ninety five%, ninety nine%, and one hundred%. If a masks is NIOSH approved then it will have a stamp of approval class printed on the respirator.

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

1. Press the mask (respirator ) firmly in opposition to 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 under your ears.

3. With both arms, mold the metal nosepiece to the shape of your nose.

4. To test match, cup each fingers over the respirator and exhale vigorously. If air flows round your nostril, tighten the nosepiece: if air flows across the edges of the respirator, reposition the headbands to suit higher and test again till there isn't any air leakage.

Earlier than selecting the best masks, it is also advised that you just converse with skilled industrial safety personnel about an assessment of your particular environment.
