N95 Respirator Mask Types: Primary Info

The N95 is the most well-liked series of particulate respirator masks that meet United States government standards. The face masks are tested to reduce exposure 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 grease aerosols:

N95, N99, & N100. These filters aren't to be used with oil aerosols. These should be used in environments uncovered to particulates which don't include oil. In many cases, the n- respirators may 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 hazards. These are one-time use masks.

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

The filter effectivity number refers to the proportion of airborne particulates that were removed in testing: ninety five%, 99%, and a hundred%. If a masks is NIOSH approved then it would have a stamp of approval class printed on the respirator.

NIOSH approved masks also come in different sizes, and a well fitting masks is vitally important. When test-fitting an N95 mask or other particulate respirator masks, follow these easy 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 place 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 each arms 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 suit better and test once more until there isn't a air leakage.

Earlier than choosing the proper masks, it is usually advised that you speak with skilled industrial safety personnel about an assessment of your particular environment.
