N95 Respirator Mask Types: Fundamental Data
The N95 is the most popular 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 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 for use with oil aerosols. These should be used in environments exposed to particulates which don't include oil. In lots of cases, the n- respirators will 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-based mostly hazards. These are one-time use masks.
P95, P99, & P100. These filters are oil proof. These respirators can be used in any setting exposed to hazardous particulates. The p- respirators are topic to time of use limitations.
The filter effectivity 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 additionally come in numerous sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or different particulate respirator mask, comply with these straightforward steps:
1. Press the mask (respirator ) firmly towards 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 each arms, mold the metal nosepiece to the shape of your nose.
4. To test fit, cup each arms over the respirator and exhale vigorously. If air flows round your nostril, tighten the nosepiece: if air flows around the edges of the respirator, reposition the headbands to fit better and test once more until there isn't any air leakage.
Earlier than selecting the best mask, it is also advised that you just speak with experienced industrial safety personnel about an assessment of your particular environment.
