Abstract
A system is designed to increase diver safety in a high-risk environment containing one or more hazardous materials. The system includes chemically-hardened surface-supplied diving equipment designed to provide full environment isolation for the diver. The system also includes a dive helmet and a surface-return exhaust system, where the surface-return exhaust system includes a demand exhaust regulator that serves as a pressure-actuated valve to enable exhausting to a breathable atmosphere outside of a dive helmet instead of exhausting into the environment containing one or more hazardous materials. The system also includes retrofittable kits enabling the upgrading of contaminant-vulnerable materials of an existing dive helmet. The system also includes fluoroelastomeric materials and components to implement in a closed circuit dive system.
