N95 Respirator Mask Types: Basic Information

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 publicity to airborne contaminates by NIOSH - the National Institiute for Occupational Safety and Health. NIOSH has nine 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 utilized in environments exposed to particulates which do not contain oil. In many cases, the n- respirators could 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 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%, 99%, and 100%. 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 several sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or other particulate respirator mask, follow 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 beneath your ears.

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

4. To test fit, cup each palms 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 fit higher and test once more until there isn't any air leakage.

Before selecting the best mask, it can be instructed that you just speak with experienced industrial safety personnel about an evaluation of your particular environment.
