N95 Respirator Mask Types: Basic Data

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 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 will not be for use with oil aerosols. These ought to be used in environments uncovered to particulates which do not include 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 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 environment uncovered to hazardous particulates. The p- respirators are topic to time of use limitations.

The filter efficiency number refers to the share of airborne particulates that were removed in testing: 95%, 99%, and 100%. 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 different sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or different particulate respirator mask, 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 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 palms, mold the metal nosepiece to the shape of your nose.

4. To test fit, cup both hands over the respirator and exhale vigorously. If air flows around 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 is no such thing as a air leakage.

Earlier than choosing the proper mask, it can be steered that you speak with experienced industrial safety personnel about an assessment of your particular environment.
