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 organic vapor
canister having a high-efficiency
particulate filter/Any appropriate
escape-type, self-contained breathing
apparatus
