N95 Respirator Mask Types: Fundamental Information

N95 Respirator Mask Types: Fundamental Information

The N95 is the most popular series 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 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 will not be to be used with oil aerosols. These must be used in environments exposed 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 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 uncovered to hazardous particulates. The p- respirators are subject to time of use limitations.

The filter efficiency number refers to the percentage of airborne particulates that were removed in testing: 95%, ninety nine%, 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 different 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 underside headband over the head and position below your ears.

3. With each fingers, 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 around the edges of the respirator, reposition the headbands to fit higher and test again till there is no such thing as a air leakage.

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