ABSTRACT:
A self-contained emergency respirator that has a mouthpiece that fits into a wearer's mouth and which is directly connected to a chemical canister that processes exhaled breath. The mouthpiece is located within a transparent hood that completely surrounds the head of a wearer and protects the wearer from a possibly toxic environment. A breathing bag encloses the chemical canister and collects the processed exhaled breath for inhalation.
