N95 Respirator Mask Types: Primary Data

The N95 is the preferred 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 uncovered to grease aerosols:

N95, N99, & N100. These filters aren't for use with oil aerosols. These should be used in environments uncovered to particulates which do not include oil. In lots of 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 solid 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 atmosphere exposed to hazardous particulates. The p- respirators are subject to time of use limitations.

The filter effectivity number refers back to the share of airborne particulates that have been removed in testing: ninety five%, 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 different sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or other particulate respirator mask, comply with these easy steps:

1. Press the mask (respirator ) firmly towards 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 hands, mold the metal nosepiece to the form of your nose.

4. To test fit, cup each fingers 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 once more until there is no air leakage.

Earlier than choosing the right mask, it is also prompt that you speak with skilled industrial safety personnel about an evaluation of your particular environment.
