The N95 is the most well-liked 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 9 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 oil aerosols:
N95, N99, & N100. These filters are not to be used with oil aerosols. These ought to be used in environments exposed to particulates which don't include oil. In lots of cases, the n- respirators might be reused multiple times.
R95, R99, & R100. These filters are oil resistant. The r- respirators can be used in atmospheres containing particulates any solid or liquid hazard together with oil-based mostly hazards. These are one-time use masks.
P95, P99, & P100. These filters are oil proof. These respirators can be used in any environment uncovered to hazardous particulates. The p- respirators are topic 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 one 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 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 each 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 nostril, tighten the nosepiece: if air flows around the edges of the respirator, reposition the headbands to fit higher and test again until there isn't any air leakage.
Earlier than choosing the proper mask, it is also recommended that you speak with experienced industrial safety personnel about an assessment of your particular environment.
