Abstract

A protective hood with air-purifying filter cartridge for safe escape from a hazardous atmosphere has a system for quickly donning the hood. A fabric strap attached to the rear of the hood has the strap lengths extending forward through circular rings near the chin. Optional enlarged ends prevent the strap from pulling rearward from the rings. Hook-and-loop fasteners are on the hood shell and the strap lengths. To deploy, the user simultaneously tugs on both strap ends to tighten the hood on the head then contacts the mating fastener parts to maintain strap tension. The hood is adjusted to optimum position on the head with a single motion. The hood is light weight and the shell is collapsible permitting the hood to fold on itself to extremely small volume for storage in an emergency kit or small personal luggage.
