Abstract
An emergency breathing apparatus which comprises a tubular frame and which carries a hood capable of extending over the head of an individual using the apparatus. The frame contains a pair of frame sections constructed of tubular members having internal chambers containing oxygen under pressure. The frame sections are normally shifted to a closed position and when opened, a switch on the frame permits the passage of oxygen into a plenum area surrounded by the hood. Moreover, the hood is capable of being attached to the individual in such fashion that an essentially air-tight plenum chamber is created around the face portion of the user of the apparatus. The apparatus also serves as a crash helmet inasmuch as the crown of the hood is reinforced. Moreover, the hood is provided with a two-way communication system which is automatically energized upon donning of the apparatus.
