N95 Respirator Mask Types: Primary Info

The N95 is the most well-liked collection 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 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 uncovered to grease aerosols:

N95, N99, & N100. These filters are not for use with oil aerosols. These must be utilized in environments exposed to particulates which do not include oil. In many cases, the n- respirators can be reused multiple times.

R95, R99, & R100. These filters are oil resistant. The r- respirators can be utilized in atmospheres containing particulates any strong or liquid hazard together with oil-primarily based hazards. These are one-time use masks.

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

The filter efficiency number refers back to the percentage of airborne particulates that had been removed in testing: ninety five%, ninety nine%, and 100%. If a masks is NIOSH approved then it should have a stamp of approval class printed on the respirator.

NIOSH approved masks also come in several sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or other particulate respirator mask, follow these easy 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 place the top headband on the back of your head above your ears. Stretch the bottom headband over the head and position beneath your ears.

3. With each arms, 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 nose, tighten the nosepiece: if air flows across the edges of the respirator, reposition the headbands to suit higher and test once more until there isn't a air leakage.

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