N95 Respirator Mask Types: Fundamental Information
The N95 is the preferred 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 exposed to grease aerosols:
N95, N99, & N100. These filters should not to be used with oil aerosols. These should be utilized in environments exposed to particulates which do not comprise 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-based hazards. These are one-time use masks.
P95, P99, & P100. These filters are oil proof. These respirators can be utilized 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 had been removed in testing: ninety five%, 99%, and a 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 numerous sizes, and a well fitting mask is vitally important. When test-fitting an N95 mask or other particulate respirator mask, observe 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 under your ears.
3. With each hands, mold the metal nosepiece to the form of your nose.
4. To test fit, cup both arms 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 isn't a air leakage.
Earlier than selecting the best mask, it can also be recommended that you just speak with skilled industrial safety personnel about an assessment of your particular environment.
