Adaptable epas hoods for acidic and contaminated environments

Abstract

A detachable hood provides head, neck, and chest protection from contaminating agents. The hood is composed of an anti-acid polyurethane fabric with polyester thread stitching and a polyurethane sealing band disposed on the stitching. The hood features a pair of elastic bands disposed on the polyurethane fabric that defines a 20 mm channel between them. A double-sided tape is disposed within the channel and is configured to adhere the fabric to the edge of a full-face mask to create a hermetic seal. In another embodiment, the hood includes a frontal opening, and the pair of elastic bands are disposed along its diameter, providing resistance and elasticity to the opening to allow for adaptation to different mask models.
