A serious and repeatable electrical hazard--compressed electrical cord and an operating table.
We describe a previously unreported hazard resulting from compression of an electrical cable by an operating theatre table. This resulted in a live wire contact to the operating table. Intermittent connection of the table to earth during a procedure resulted in triggering of a residual current device mitigating the effects of the hazard. The actual cause was not readily identified as the devices connecting the table to earth were considered most likely to be the source of the current. There was potential for significant injury to the patient and theatre staff which would have been diminished if staff had had a better understanding of the electrical safety equipment in use. We examine the underlying causes of the accident, discuss electrical safety and correct use of safety devices in the operating theatre, and propose guidelines for appropriate management.
