N95 Respirator Mask Types: Fundamental Info

The N95 is the most well-liked 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 exposed to grease aerosols:

N95, N99, & N100. These filters will not be to be used with oil aerosols. These ought to be used in environments exposed to particulates which don’t comprise oil. In many cases, the n- respirators might be reused a number of 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-based mostly hazards. These are one-time use masks.

P95, P99, & P100. These filters are oil proof. These respirators can be utilized in any setting exposed to hazardous particulates. The p- respirators are topic to time of use limitations.

The filter efficiency number refers to the proportion of airborne particulates that were removed in testing: 95%, ninety nine%, and a 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, follow these easy 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 below your ears.

3. With both hands, 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 round your nose, tighten the nosepiece: if air flows around the edges of the respirator, reposition the headbands to fit better and test again until there is no air leakage.

Before selecting the best mask, it can also be urged that you simply speak with experienced industrial safety personnel about an assessment of your particular environment.
