N95 Respirator Mask Types: Primary Information

The N95 is the preferred series of particulate respirator masks that meet United States government 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 lessons, 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 will not be for use with oil aerosols. These must be used in environments exposed to particulates which don’t contain 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 utilized in atmospheres containing particulates any stable 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 utilized in any atmosphere uncovered to hazardous particulates. The p- respirators are subject to time of use limitations.

The filter efficiency number refers to the percentage of airborne particulates that have 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 several sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or different particulate respirator mask, comply with 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 position 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 form of your nose.

4. To test fit, cup both hands 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 higher and test again until there isn’t a air leakage.

Earlier than choosing the right mask, it can be suggested that you just speak with skilled industrial safety personnel about an evaluation of your particular environment.
