Is electric shock drowning a danger near swimming pools, spas, and hot tubs?

by Nils Deacon, Manager, Inspections and Rating Services

A previous Underwriters’ Corner discussed Electric Shock Drowning – ESD which can occur when electric current from a boat or dock leaks into the water and incapacitates or electrocutes a nearby swimmer.

However, other water activities can be hazardous due to improper electric wiring around pools, spas, and hot tubs. According to the CPSC – Consumer Product Safety Commission, deaths occur almost every year from electrocutions in swimming pools and spas / hot tubs.

Symptoms of electrocution in water may be a tingling sensation as well as muscle cramps and inability to move. Observing panic behavior of swimmers, or motionless swimmers, can be signs of active electrocution. Underwater lights that are flickering unusually or not operating correctly are indications of possible electric danger according to the CPSC.

A swimmer should get out of the water quickly, without using a metal ladder if possible. If outside of the water, turn off electricity, call 911 and assist injured swimmers when safe (American Red Cross).
