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/Any appropriate
escape-type, self-contained breathing apparatus
