Electric Shock Hazards.

The prime concern of electrical hazards in operational and research diving chambers is the contributing factor to fire hazards. The problem of chamber fire safety and the role of electrical sources of ignition is covered in another section. The other electrical related hazard is that of electrocution. In a dry diving chamber potential electrocution is ever-present during the use of instrumentation and current consuming devices. Sea water and perspiration increase the shock hazard potential, and in a wet chamber the hazard becomes even more significant. Persons in a diving or decompression chamber are generally well grounded, crowded, and confined. In cases of severe electrical shock requiring immediate treatment, rescue is difficult or impossible.
