RICHMOND, Va. (WRIC) — A local tragedy on Smith Mountain Lake serves as a stark reminder of the dangers of Electric Shock Drowning (ESD). The Bedford County Sheriff’s Office reported finding the body of a man believed to have been electrocuted while on a private dock on Thursday, July 4.

According to the Electric Shock Drowning Prevention Association, ESD is a drowning resulting from paralysis caused by electrical currents in the water. If the currents are high enough, electrocution can occur.

ESD is a silent and odorless killer. Damaged equipment and wiring around boats and docks can leak electricity into the water, creating an invisible hazard with no warning signs.

Freshwater poses a greater risk for electric shock drowning compared to saltwater. This is because our bodies are better conductors of electricity than freshwater. Simply put, the current finds it easier to flow through us than the surrounding water.

The Electric Shock Drowning Prevention Association gives these safety tips before you take to the water this summer.

While You’re Swimming:

• The Tingle Test: If you experience a tingling sensation in the water, get out immediately. This could be a sign of a dangerous electrical current.
• Maintain Distance: Stay at least 50 yards away from docks, boats, and other electrical equipment.
• Warning Signs: Post warning signs around your dock to notify others about potential dangers. You can print one online here.

For Boat Owners:

• Inspections: Schedule annual electrical inspections for your boat by a qualified electrician. Faulty wiring is a major cause of ESD.
• Follow the rules: Codes and standards protect when water is entered accidentally. Install ground fault protection on all electrical systems used by docks and boats.

In Case of Emergency:

• Call 911 Immediately: If you witness someone experiencing ESD, the most important step is to call emergency services right away.
• Don’t jump in: Resist the urge to jump in and rescue someone from ESD. The current could also harm you. Instead, try to extend a long object like a pole to pull the person away from the dock.
• Turn Off the Power Source (if possible): If it’s safe to do so, locate the power source and turn it off to prevent further harm.
