Respirator Recommendations NIOSH
At concentrations above the NIOSH REL, or where
there is no REL, at any detectable concentration: (APF = 10,000)
Any self-contained breathing apparatus that has a full facepiece and is
operated in a pressure-demand or other positive-pressure mode/(APF =
10,000) Any supplied-air respirator that has a full facepiece and is
operated in a pressure-demand or other positive-pressure mode in
combination with an auxiliary self-contained positive-pressure breathing
apparatus
Escape: (APF = 50) Any air-purifying,
full-facepiece respirator (gas mask) with a chin-style, front- or
back-mounted canister providing protection against the compound of
concern/Any appropriate escape-type, self-contained breathing apparatus
