The N95 is regarded as the popular group of particulate respirator masks that meet United States government standards. The face masks are tested to lessen exposure to airborne contaminates by NIOSH – the National Institiute for Occupational Safe practices. 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 what sort of filter tests in environments subjected to oil aerosols:
N95, N95 Mask, & N100. These filters should not be used with oil aerosols. These ought to be utilized in environments subjected to particulates that don’t contain oil. Oftentimes, the n- respirators can be reused several times.
R95, R99, & R100. These filters are oil resistant. The r- respirators may be used 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 may be used in any environment exposed to hazardous particulates. The p- respirators are be subject to use of use limitations.
The filter efficiency number refers to the number of airborne particulates which were removed in testing: 95%, 99%, and 100%. If the mask is NIOSH approved this may stamp of approval class printed around the respirator.
NIOSH approved masks are also available in sizes, and a well fitting mask is quite crucial. When test-fitting an N95 mask or any other particulate respirator mask, follow these easy steps:
1. Press the mask (respirator ) firmly from the face with all the outside nosepiece for the bridge of your nose.
2. Stretch and position the top headband on the back of the head above your ears. Stretch the lower headband on the head and position below your ears.
3. With hands, mold the metal nosepiece on the type of onto your nose.
4. To try fit, cup your hands within the respirator and exhale vigorously. If air flows around your nose, tighten the nosepiece: if air flows around the edges from the respirator, reposition the headbands to suit better and test again until there is absolutely no air leakage.
Before choosing the correct mask, it is usually suggested which you talk to experienced industrial safety personnel about a assessment of your respective particular environment.
