The Hidden Hazard in the Water: Electric Shock Drowning

Cass County Electric Cooperative (CCEC) urges families and water recreation enthusiasts to be aware of an often-overlooked but serious danger: electric shock drowning (ESD). While wearing life jackets is standard water safety, ESD is an invisible threat that can strike without warning—especially near docks, boats, and marinas.

Electric shock drowning occurs when electricity from faulty wiring or malfunctioning equipment enters the water. This can paralyze muscles, causing swimmers to drown, or lead to severe injuries and even cardiac arrest. Unlike visible hazards, energized water looks completely normal—making it even more dangerous.

Common sources of ESD include boats connected to shore power, aging dock wiring, and improperly installed pool or hot tub equipment. According to the Electric Shock Drowning Prevention Association, most ESD incidents happen around marinas and docks with AC power systems.

CCEC stresses these important safety reminders:

• Never swim near marinas, docks, or boats that are plugged in.
• If you feel a tingling sensation, pulsing, or anything unusual in the water, tuck your legs up and swim away from the suspected source—not toward ladders or docks.
• If you see someone struggling and suspect ESD, do not jump in to help. Instead, cut the power if possible, throw a life ring, and call 911.

Electricity and water don’t mix. Even a small leak of current can be deadly. What was safe yesterday could become hazardous today. Regular inspections and proper maintenance are key.

Help protect yourself and others:

• Ensure dock and boat electrical systems are installed and inspected by professionals.
• Talk with neighbors and marina operators about ESD risks.
• Spread awareness about this preventable danger.
