N95 Respirator Mask Types: Primary 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 exposure to airborne contaminates by NIOSH – the National Institiute for Occupational Safety and Health. NIOSH has nine 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 will not be to be used with oil aerosols. These must be utilized in environments exposed to particulates which don’t 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 solid 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 utilized in any environment exposed to hazardous particulates. The p- respirators are topic to time of use limitations.

The filter effectivity number refers back to the share of airborne particulates that have been 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 additionally come in different sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or different particulate respirator mask, observe 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 beneath your ears.

3. With both fingers, mold the metal nosepiece to the shape of your nose.

4. To test fit, cup each palms over the respirator and exhale vigorously. If air flows around your nostril, tighten the nosepiece: if air flows across the edges of the respirator, reposition the headbands to fit better and test once more till there is no such thing as a air leakage.

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