July 4, 2012

Lake of the Ozarks, MO.   A 13 year old girl and her 8 year old brother were killed by electricity while swimming near a private dock.  Officials said the dock was not protected by a GFCI as required.  The electrical fault may have come from a boat lift or a water slide pump.

5.      

July 4, 2012

German Creek Marina on Cherokee Lake, Bean Station, TN.  A 10  year old and 11 year old boys were killed by electricity in the water at a TN marina while swimming between 2 docked houseboats.  An 8 year old girl also swimming with the boys was shocked but pulled to safety.  Several adults and another 12 year old boy were shocked trying to rescue the 2 boys.  Faulty houseboat wiring on one of the boats is believed to be one of the causes.

6.

June 27, 2012

Celebration, FL.  An 11 year old girl was electrocuted when she reached into a mini golf pond at an Orlando, FL resort to retrieve a golf ball.  A man trying to help her was also shocked.  The cause was faulty pond pump that was not protected by the required GFCI.  Water came in contact with the pumps windings and electrified the small cement pond on the mini golf course.

May 8, 2012

Lake Sinclair, Palatka FL.  A 25 year old woman was apparently electrocuted when she reached from the water and touched either a box or bare wire on the dock (it was being worked on at the time).  Another woman in the water was shocked when she pulled the 25 year old away from the dock and held her head above water.  She could not be revived at the scene.

8.

Aug 15, 2011

Traverse City, MI, Clinch Marina.  An 18 year old boy died in West Arm Great Traverse Bay when an electrical fault (reportedly from dock wiring) caused current to enter the water where the boy and a friend were swimming.  The friend reported feeling electricity in the water.  “No Swimming” signs were posted in some locations in the marina.

9.

May 28, 2011

Lake City, MN.  A 50 year old man was electrocuted in Lake Pepin near a boat lift which had exposed wiring.  His dog was in the water and was shocked and began to sink.  Another man jumped in to rescue the dog but was shocked (he escaped the water).  The 50 year old man then jumped in for his dog and appeared to have been electrocuted.

10.

July 26, 2010

Lake Freeman, Carroll County, IN.  A 13 year old boy was swimming with 3 other children when they started to feel a tingle.  The 13 year old attempted to exit the water at the dock but fell back into the water.  The other children managed to exit the water.  A water-soaked electrical junction box was located on the dock nearby and is the likely source for the electrical current in the water.

11.

July 14, 2010

Pella, IA.  Two boys, 15 and 16 years old drowned in a local swimming pool.  The electrical supply for the pool lights has been suspected as being faulty.  The lights were supposedly secured several years before.  The boys were non-swimmers.  Electric shock is a possible cause of death in this case.  The investigation continues. 

12.

July 10, 2010

York, SC.  A 54 year old man died after jumping into a swimming pool to help his granddaughter.  The granddaughter was receiving a shock from the pool’s railing when the man jumped in to help her.  He grabbed the pool’s railing and reportedly “stuck” to it.  His grandson reported that he had felt electricity in his chest when near the edge of the pool (until a light was turned off).  Electric shock is the probable cause of death.

13.

June 21, 2010

Smith Lake, Birmingham, AL.  A 16 year old boy was climbing a dock ladder when he suddenly fell back into the water.  He was immediately unresponsive when recovered by friends.  Electrocution (from an energized dock ladder) is suspected as a possible cause of death.

14.

June 2010

Lake Waccamaw, NC.  A boy was killed swimming near a boat lift.  A the owner was told by another child that he was feeling tingles in the water.  The owner reached up, touched the boat lift and was shocked.  He told the other kids to get out of the water.  After exiting he noticed one boy face down in the water.  He could not be revived at the scene.  There was an open ground in the lines from the house to the dock, and one of the small junction boxes under the dock was filled with water.  The cause may have also been a fault to the lift motor.

15.

May 29, 2010

Stonewall Jackson Lake, WV.  A 15 year old boy was climbing onto the swim platform of a boat.  When he touched the ladder he received an electrical shock and he fell back into the water and reportedly drowned.  A girl still in the water felt the shock and was treated and released from a local hospital.  Cause was improper repair of the pedestal end of shore cord (hot and ground were reversed). It is likely this was an electrocution rather than a drowning.

16.

August 23, 2008

Lake Hamilton, Hot Springs, AR. 14 year old girl swimming near a metal swim ladder with a 7 year old boy and his mother near by.  Without warning the boy began to scream and his mother became incapacitated on the swim ladder. As the girl attempted to help the boy she sank out of sight. The boy’s father pulled him to safety and helped his wife onto the dock. Preliminary investigation revealed an unbonded metal pole, welded to the dock, on which was mounted a halogen light, which had just been turned on by its photo cell, and had an AC fault due to chafed wires which energized the dock frame and ladder. Boy and mother required hospitalization. Voltage to ground on the ladder measured at 103 VAC. The girl was recovered later that night.

17.

July 28,2007

Lake of The Ozarks, MO Twenty four year old female attempted to exit the water using a metal ladder at the end of a private dock. She apparently experienced a paralyzing electric shock which caused her to fall back into the water and drown. Several people had reported being shocked by the ladder and the dock owner had gone to shut the power off. The dock power wiring termination was found submerged under the dock near the exit point.

18.

July 24, 2006

Lake Lanier, Cumming, GA. Seventeen year old boy in water near a private dock, working on a jet ski with two friends, was overcome by electric shock. Extension cord with damaged insulation caused the metal dock to become energized. Friends also shocked, and partially disabled, could not help their friend. Father of victim fought paralyzing shock and pulled unconscious son away from dock – he could not be resuscitated. Investigation planned.

19.

July 14, 2006

River Street Marina, Port Huron, MI. A 20 year old man jumped, or fell, into the water from the pier behind a 29’ boat, moored stern too. He became disabled as he attempted to climb onto the swim platform. Two friends attempting to pull him onboard reported being shocked. He could not be resuscitated. Shock induced ventricular fibrillation likely cause of death. The next day an inspector reported 107vac in the water behind the boat. Subsequent investigation confirmed the voltage behind the boat. The cause was an AC to DC fault in the battery charger energizing the underwater gear and no AC to DC bonding connection.

20.

June 24, 2006

Brady Mountain Resort, Lake Quachita, Hot Springs, AR.  A 14 year old boy died from electric shock while swimming near a houseboat.  A friend was also shocked and taken to a hospital and released.  A man jumped in to help and was rendered unconscious but was unharmed after regaining consciousness. The cause appeared to be inserting a shore cord with a 30A/125V (L5-30) plug (with the grounding pin bent back) into a 50A-125/250V receptacle in such a way so as to energize the neutral, which was connected to the bonding system, thereby energizing the hull.

21.

June 10, 2006

Lake Michigan, Racine Harbor, WI.  A 56 year old man was killed when he went swimming from the stern platform of a boat.  Inquest listed death as "Accidental Electrocution" and did not establish a root cause.  Victim's wife stated that the Reverse Polarity light flickered on and went out when power applied to vessel.  Comment:  A reverse polarity situation along with a grounded neutral can energize underwater metals on a boat.

22.

May 22, 2006

Weiss Lake, Cherokee County, AL.  A 24 year old young man was killed while in the water near a pier.  He was attempting to rescue his friend who had become paralyzed by an electric shock while trying to exit the water via a metal ladder.  Another friend was also disabled by shock as he entered the water to assist. The two young men, who were shocked, were not seriously injured. There was an electric windmill on a metal tower attached to the ladder, and was apparently powered by an incorrectly modified extension cord, and which may have been connected to a non-functioning GFCI outlet. A bystander on the dock pulled the power cord just in time, or there may have been two more victims.  Investigation underway.

23.

Mar 18, 2006

Summerset Lake near Desoto, St. Louis, MO.  In the early evening a teenage boy became paralyzed by electric shock, and drowned, while attempting to swim toward a metal ladder attached to a private dock. Two friends were rendered unconscious but were resuscitated and required hospitalization. During several investigations, initially and over the next months, it was determined that the dock wiring was properly installed, the metal dock frame and ladder were bonded, and no loads were operating at the time of the accident. However, clamping the dock supply cable with an AC ammeter disclosed 10 amps flowing (likely in the ground wire) and 4-6 VAC was measured approximately 2 ft. away from the ladder on several separate occasions. The subsequent legal action resulted in a jury finding the local utility at fault. It seems that a near-by underground power distribution cable had a defective (or missing) neutral which caused the neutral current to seek a path back to the substation through the earth and into the lake. This earth leakage current concentrated at the bonded swim ladder resulting in a lethal gradient of more than 2 V/Ft near the ladder. These earth leakage currents are fairly common but this is the first serious incident we have recorded due to this phenomenon.

24.

June 27, 2005

Scott’s Creek Marina at Cave Run Lake, Moorhead, KY.  A 19 year old girl drowned, while in the water near a houseboat, due to electric shock caused by a battery charger in the engine compartment which had become partially submerged and energized the hull. Owner had rewired the boat with no bonding system. Another girl sustained burns on her legs while reaching into the water to help the victim.  A nearby rescuer swam toward the scene and was shocked and paralyzed by the electrical field. Only two feet from the victim he had to turn around and swim out of the field to survive.

25.

Sept. 2004

Lake Of The Ozarks, MO 22 year old male stepped on an electrical cable upon exiting the water after swimming behind a private residence – fell face down into water unconscious – could not be revived. No information on cable.

26.

Sep 13, 2004

Ross Barnett Reservoir, Ridgeland, MS.  A 16 yr old boy was swimming in the marina when he approached a houseboat.  He screamed as if in pain and disappeared under the water.  He could not be revived after divers recovered his body.  A friend in the water also felt a shocking sensation.  The cause was a home made shore cord, hard wired to the panel which was passed through a hole in sheet metal siding with no chafe protection.  The insulation was cut by boat motion and shorted the hot conductor to the siding.  The siding was not adequately grounded to the shore grounding system but was connected to the boat’s bonding system, which caused the hull to go up in potential killing the boy.

27.

Aug 8, 2004

Lake Travis, Austin, TX. Young man, in good health, swimming, in evening, unobserved, between two sections of marina dock – disappeared. Came to surface two days later.

 June 19, 2004

Lake Waccamaw, NC Ten year old boy drowned while swimming with friends near a private dock boat lift that had just been raised from the water. An adult reported a heavy shock when touching the lift and several children in the water reported being shocked. Victim was noticed motionless face down nearby – could not be revived. Lift frame had become energized and the bonding conductor from the supply panel was not connected.

29.  

 June 5, 2004

Lake Wylie, Charlotte, NC. Two young boys swimming at bow of houseboat called for help. Father of victim and friend rushed forward – boy on ladder said he was being shocked, other boy in water not moving. Friend rushed aft to pull shore cord as father went onto water – his son could not be resuscitated. May not be exact sequence. Causes of energized hull were substantial errors in wiring on the dock as well as on the boat, apparently done by non qualified individuals.

30.

 Aug 3, 2003

Bull Shoals Lake, Bull Shoals, AR. Diver found Aug. 5 in shallow water 8 ft. from his dock, drowned. Incorrectly wired dock junction box caused 117 VAC to appear on metal dock components. Rescue diver reported feeling shock sensation 20 ft. from dock!

German Creek Marina on Cherokee Lake, Bean Station, TN.  A 10 year old and 11 year old boys were killed by electricity in the water at a TN marina while swimming between 2 docked houseboats.  An 8 year old girl also swimming with the boys was shocked but pulled to safety.  Several adults and another 12 year old boy were shocked trying to rescue the 2 boys.  Faulty houseboat wiring on one of the boats is believed to be one of the causes.

4.

June 27, 2012

Celebration, FL.  An 11 year old girl was electrocuted when she reached into a mini golf pond at an Orlando, FL resort to retrieve a golf ball.  A man trying to help her was also shocked.  The cause was faulty pond pump that was not protected by the required GFCI.  Water came in contact with the pumps windings and electrified the small cement pond on the mini golf course.

5.

May 28, 2012

Lake of the Ozarks, MO.  3 women were shocked while swimming  near a dock.  Someone turned off the power fast enough to save them.  One needed CPR at scene.  All survived.  The older dock had no GFCI protection and an “inadequate ground wire from dock to shore”.

6.

August 28, 2011

Near Shady Beach, Norwalk, CT.  A dog was electrocuted in floodwater from recent storm (Hurricane Irene).  The two women walking their dogs felt electrical shocks (other dog, leashed, survived).  Witnesses report “water boiling” where a grounding cable was entering standing water.  This is indicative of electrical current in the water.

7.

March 18, 2011

Houston, TX.  A dog jumped into a neighborhood retention pond with fountain and was killed by an electric current in the pond.  A man went in after the dog but when he was ankle deep he could feel the strong electric current in his feet so he retreated.  Power was secured to the fountain.  Comment: Had the man dove into the pond, he could have become a casualty as well.

8.

September 5, 2010

Lake at Perrine Wayside Dog Park, Miami, FL.  Man playing fetch with dog threw object into a lake.  The dog jumped in and swam toward a fountain in the center of the lake.  The dog began yelping and struggling.  The man went in the water to help his dog, but was stopped by electric shocks and could not reach the dog.  The dog died, the man survived.  The fountain was turned off but it was still putting electrical current into the water.  It was removed for inspection.

15.

Sep 2007

Franklin Lock Campground on the Caloosahatchee River, FL.  Boat docked in freshwater marina receiving AC shore power.  Owner was cleaning prop shaft under the boat using a metal scraper.  As his foot touched the bottom and the scraper connected the shaft and the strut he felt an electric shock which caused his “teeth to clench and muscles to contract”.  He also saw blue sparks at the scraper.  After the shock he was able to exit the water and observed that one of two 30amp shore power breakers had tripped.  He was not wearing a wetsuit.

16.

August 28, 2007

Private pond, Eden, NY 22 year old male entered the pond in an attempt to rescue his dog, which was in great distress, and was thrown back and lay unresponsive. His father dragged him from the water and started CPR which was continued by the rescue squad on the way to the hospital, where he is still recovering as of 9/1. Submersible irrigation pump was considered likely cause.

17.

July 20, 2007

Lake Arcadia, Edmond, OK Adult male entered water at the end of a private dock and was immediately paralyzed by electric shock, and began to sink. His wife, reaching from the dock, kept his head above water. A bystander, entering the water from his boat was also shocked so he got back into the boat and assisted the wife in pulling the man onto the dock. High water had submerged the electrical outlets at the end of the dock.

18.

July 01, 2007

Collins Bay, Lake Ontario, Kingston, ON. As a SCUBA diver, with no wet suit, approached a moored sail boat he felt a tingling sensation. Approaching closer he experienced a moderate electric shock so he backed away. Later examination disclosed damage to a steel dock section at the boat’s stern and the battery charger was found to have a “short circuit”. The condition of the bonding system was not reported.

19.

August, 2006

Lake Michigan, Racine, WI.  Owner decided to check underwater as he was having vibration on one engine.  He donned scuba gear and jumped in water.  When he touched the bronze prop he was hit with current that almost paralyzed him causing great difficulty in breathing.  He was able to get away from the zone of danger.  Cause is thought to be the boat in the next slip.  A yellow barrel connector on the water heater Neutral #16 wire was loose, due to the terminal being the wrong size and not correctly crimped.  It heated up which burnt terminal insulation and shorted the hot to the grounded case.  As the phase did not see excessive current, the breaker did not trip.  The neutral dock pedestal socket pins had corroded due to poor connection and the ensuing heating so that eventually only intermittent connection was made.  The diver’s wetsuit may have saved his life.  He was only inches from the neighboring boat when touching the prop on his boat (which provided the path back to the source).

Lake L’Homme Dieu, Douglas County, MN. Three men were nearing an aluminum dock in an outboard boat (aluminum hull?) when the prop caught on an extension cord laid under water (powered a boat lift), and were severely shocked as they entered the water. Possibly two of the three men entered the water to rescue the third man who had fallen face down into the water, half out of boat, and was not moving – exact sequence not known. A bystander unplugged the cord. The third man spent several days in the hospital. No investigation planned.

Brooklyn, NY.  A diver went into the water behind a boat in this small, private marina.  He surfaced seconds later complaining about tingling and pain in his arm.  A probe in the water measured 40vac to ground behind the boat.  Cause was determined to be a neutral-ground short on a recently installed water heater (although there was most likely a bad ground too at that pedestal to cause this).  He was wearing a short, spring wet suit.

Sahauro Lake, AZ, a man-made, freshwater lake near Phoenix.  A man was diving to perform maintenance on a dock structure.  He left the water after feeling a tingling sensation in the water near a pontoon houseboat.  The shore cable was disconnected from the boat and the diver resumed his work without further incident.  The cause may have been an improperly wired battery charger on the boat.

Sacramento River, CA.  Man entering water around several boats (being supplied by genset power from one of the boats) receives shock in water.  Two other men jump in to rescue man.  One of the 2 rescuers became imperiled.  Generator secured immediately.  Incorrect wiring on one boat caused a ground fault which introduced current into the water between boats.

Lake Barkley, Grand Rivers, KY. After receiving permission from marina two adult women went swimming near their rented houseboat. As they started back to the boat from the swim slide entry point both felt a strong electric shock sensation, and had the presence of mind to swim away from the boat! A relative entered the water and felt the same thing – which disappeared when the boat was disconnected from shore power. Close call was brushed off by staff so no action was taken to locate source of fault current. A fatality waiting to happen!

Green River, Campbellsville, KY.  Marina manager using Hioki clamp-on ammeter checking shore cords for leakage and discovered one houseboat with 4 amps on one of two shore cords.  Hull potential to dock ground 8 VAC and owner commented that one of his children reported a tingle in the water!!  Boat had just been reassembled after being trucked from Texas and problems were being experienced with 120 VAC deck light.  Deck lights were rewired and neutral / ground fault in inverter was cleared – leakage current no longer exists.

Niagara River, Grand island, NY – On the dock behind his home the owner watched his dog sink near a steel piling while retrieving a ball. He jumped into the water to rescue the dog and found himself sitting on the bottom in 5’ of water completely paralyzed. In a few seconds he began getting tunnel vision and assumed he was going to die. Within the next few seconds a slight current moved him about 4’ away from the steel pile. He was able to get his head above water and move another 8’ to a ladder. A romex cable, which powered a light on top of the piling, had chaffed and caused the energized conductor to contact the pile. The dog was lost.

August, 1995

Lake Cumberland, KY, Jamestown Resort and Marina.  Seven children swimming behind houseboat received electrical shocks (no fatalities).  Lights went out on boat and children immediately started screaming.  Cause was loss of neutral, a neutral-ground connection on the air conditioning system and a poor grounding connection on the shore cord.  The grounding connection deteriorated when cooking loads were energized causing a loss of return path to the source (reason lights went out).

July, 1981

Brackish water on the Connecticut River in Essex, CT.  Diver checking zincs felt strong “electric pulses” as he approached the boat so he backed away.  After securing power to the boat, the electric pulses were gone (exact fault unknown)

Follow-up

Follow-up to #9 in the Electric Shock Drowning Section above:
Lake Travis, Austin, TX.  Because of this accident the manager of a neighboring marina now shuts down power to the docks whenever an employee enters the water to do any kind of service. In Nov., 2005, an employee who was in the water, to move the feeder cables that run near the pier access ramp, discovered badly damaged insulation. A fatality was likely prevented because the power had been turned off.
