Abstract

A protective breathing apparatus for traversing toxic smoke zones, having a face mask portion covering the nose and mouth of a user in a sealed relationship to the face, a pleated flexible vessel made of a gas-impermeable material and capable of containing ambient air, and a sealed air passageway between the mask and vessel. When not in use, the vessel can be tightly compressed and reduced in size for easy portability; however, for use, the vessel can be instantly expanded, drawing at least 60 cubic inches of ambient air therein.
