N95 Respirator Mask Types: Primary Data

The N95 is the preferred collection 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 courses, 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 for use with oil aerosols. These needs to be utilized in environments uncovered to particulates which do not include oil. In lots of cases, the n- respirators can 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 strong or liquid hazard including oil-primarily based hazards. These are one-time use masks.

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

The filter efficiency number refers to the share of airborne particulates that had been removed in testing: ninety five%, ninety nine%, and a hundred%. If a mask is NIOSH approved then it’ll have a stamp of approval class printed on the respirator.

NIOSH approved masks additionally come in numerous sizes, and a well fitting mask is vitally important. When test-fitting an N95 masks or different particulate respirator masks, observe these simple 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 bottom headband over the head and position below your ears.

3. With both palms, mold the metal nosepiece to the form of your nose.

4. To test match, cup each 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 suit higher and test once more until there isn’t any air leakage.

Earlier than choosing the proper masks, it is usually advised that you simply speak with experienced industrial safety personnel about an evaluation of your explicit environment.
