What is ESD, and How Can You Avoid This Silent Killer?


Sadly, while ESD deaths are more and more frequently making the news, it becomes clearer that many people are unaware of the dangers of Electric Shock Drownings (ESD) that can occur nears docks with AC power near them.  If you would rather watch then read, check out this video explaining the dangers of alternating current and marinas:

WHAT IS ELECTRIC SHOCK DROWNING?
Electric Shock Drowning (ESD) is the result of the passage of a typically low level AC current through the body with sufficient force to cause skeletal muscular paralysis, rendering the victim unable to help himself / herself, while immersed in fresh water, eventually resulting in drowning of the victim.  Higher levels of AC current in the water will also result in electrocution.  Electric Shock Drowning (ESD) has become the catch all phrase that encompasses all in-water shock casualties and fatalities.

Although Electric Shock Drowning can occur virtually in any location where electricity is provided near water, the majority of Electric Shock Drowning deaths have occurred in public and private marinas and docks.  The typical victim of Electric Shock Drowning is a child swimming in or around a marina or dock where electricity is present.  The electricity that enters the water and causes Electric Shock Drowning originates from the wiring of the dock or marina, or from boats that are connected to the marina’s or dock’s power supply.

WHY IS ELECTRIC SHOCK DROWNING A SILENT KILLER?

  • There is no visible warning or way to tell if water surrounding a boat, marina or dock is energized or within seconds will become energized with fatal levels of electricity.
  • In most circumstances victims do not immediately feel electrical current when they enter or swim in the water around a marina or dock, thus giving the victims the false impression that it is “safe” to swim.  Most often, electricity enters the water when an electrical fault occurs aboard a boat.  Often, the electric fault occurring aboard the boat is intermittent.  For example, the fault that places deadly current into the water may only occur when a light switch is turned on, or when a hot water heater, battery charger, A/C unit or other electrical device cycles on.  Water can appear and feel “safe” and in a split second become energized with deadly electricity.
  • Under the typical scenario, the victim’s muscles become paralyzed by the electrical current, he or she is unable to swim, and ultimately drowns.  Unless there is a witness nearby to experience and report the sensation of electric shock in the water, the victim’s death is typically labeled a common drowning.  In the vast majority of Electric Shock Drownings, the victim’s autopsy shows no signs of electrical injury and investigators often never learn that electricity was the cause of the drowning.
  • Until very recently, there has been very little public awareness about the danger of Electric Shock Drowning.  As a result, Electric Shock Drowning continues to kill and new families are devastated on a yearly basis with very little public awareness.


HOW FREQUENTLY DOES THIS OCCUR?

  • How many unexplained drownings of healthy vibrant people around boats and marinas have there been?  The answer – many.
  • How many of these unexplainable drownings have likely been caused by Electric Shock Drowning instead of cramping, excessive alcohol use, or some other factor? The answer – many.
  • The number of verifiable in-water deaths due to Electric Shock Drowning is, in all likelihood, just the tip of the iceberg.

You might notice we didn’t include a “green light for swimming” device in our Must Have Accessory list; we believe the best way to avoid ESD is to avoid swimming near docks at all.  But, these devices just might save a life!
