(2021) Static Electricity & Grounding in Hyperbaric Chambers (1.0 hour)

Robert Sheffield, CHT and Francois Burman, Pr. Eng.

April 2021

Static electricity is a safety concern in hyperbaric chambers. The National Fire Protection Association Health Care Facilities Code (NFPA 99) contains static control requirements for hyperbaric facilities and grounding requirements for hyperbaric chambers, chamber furniture, and chamber occupants. Hyperbaric Safety Directors should ensure that static control and grounding requirements are met and the continuity of grounding is tested periodically. All members of the hyperbaric team (e.g. physicians, nurses, chamber operators) should have a basic understanding of static electricity and grounding.
