Abstract
A quick-donning protective hood assembly for respiratory protection from smoke and noxious gases. The assembly consists of a clear 'TEFLON' film hood (12) having a scrubber canister (20) and an exhaust valve (42) supported thereon. A neck seal (14) is connected to the lower marginal edge of the hood. A springlike hoop (16) is connected to the lower marginal edge of the hood. A bib (18) is carried by the springlike hoop and supports an oxygen generator (22) which is interconnected with the scrubber canister by an oxygen supply line (24). Waist straps (54) extend from the sides of the bib and may be adjusted to secure the bib about the wearer. The assembly can be stored in a cylindrical storage container with the hoop being collapsed. When the assembly is withdrawn from the storage container, a lanyard (62) will initiate the operation of the chemical oxygen generator. In addition, chemiluminescent devices (64) are secured to the hoop when in the storage container, and the springing open of the hoop when withdrawn from the storage container will initiate a chemiluminescent reaction within the illuminating devices. The springlike hoop will additionally spring the assembly open to position the components for quick donning.
