Abstract
The personal escape breathing apparatus comprises exhalation and inhalation bags connected by a carbon dioxide absorption canister, a chemical oxygen generator connected to the exhalation bag and a relief valve for releasing built-up gas within the exhalation bag. The two unequal size bags provide a flexible volume sufficient to store the user's vital capacity a surface area sufficient to cool gas heated from the exothermic reaction of O.sub.2 generation and CO.sub.2 absorption, but the bags are readily foldable to minimize the stored size. The two bags are integrally formed on a flexible, gas impermeable sheet which serves both as the back walls of the bags as well and as a support collar which extends from the bags and has a hole for passing the user's head therethrough. The apparatus also comprises a flexible transparent hood and nose block to protect the user from the hostile environment.
