N95 Respirator Masks Types: Basic Info
The N95 is the preferred 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 exposed to grease aerosols:
N95, N99, & N100. These filters are usually not to be used with oil aerosols. These must 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 stable or liquid hazard together with oil-primarily based hazards. These are one-time use masks.
P95, P99, & P100. These filters are oil proof. These respirators can be utilized in any setting exposed to hazardous particulates. The p- respirators are topic to time of use limitations.
The filter efficiency number refers to the share of airborne particulates that have been removed in testing: ninety five%, 99%, and a hundred%. If a mask is NIOSH approved then it can 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 masks 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 place the highest headband on the back of your head above your ears. Stretch the underside headband over the head and place under your ears.
3. With both hands, mold the metal nosepiece to the form of your nose.
4. To test match, cup each fingers over the respirator and exhale vigorously. If air flows round your nose, tighten the nosepiece: if air flows around the edges of the respirator, reposition the headbands to fit better and test again till there is no such thing as a air leakage.
Earlier than choosing the proper masks, it is usually instructed that you simply communicate with skilled industrial safety personnel about an assessment of your specific environment.
