HAZARDOUS-ENVIRONMENTAL DIVING SYSTEMS

摘要

This disclosure provides a protective diving system for isolating a diver from a hazardous diving environment. The protective diving system can include a dry suit system including a dry suit and a surface exhaust valve coupled to the dry suit, and a return-surface exhaust assembly configured to exhaust gas from the dry suit system to a breathable atmosphere outside of the diving environment of the diver. The surface exhaust valve is configured to receive gas from the dry suit and exhaust gas to the return-surface exhaust assembly without exhausting to the surrounding diving environment. The protective diving system can further include one or more chemically- resistant components, where the chemically-resistant components include a fluoroelastomer.
