What is an electrocution hazard?
Electrocution is a fatal injury caused by electric current passing through the body.
An electrocution hazard is any condition on a job site where an individual is at risk of death from contact with a live electrical source.
What is the difference between electrocution and electric shock?
While the terms are often used interchangeably, electrocution and electric shock refer to different outcomes.
- Electrocution is fatal— death caused by an electric current passing through the body.
- Electric shock is non-fatal— injury from an electric current may cause burns, muscle spasms, or cardiac issues.
Severe electric shocks can result in life-altering injuries, but they are survivable. Electrocution, by definition, results in death.
How common is electrocution in the construction industry?
Electrocution remains one of the leading causes of death on construction sites. According to the Bureau of Labor Statistics, in 2020, electrocutions accounted for 5.3% of all construction fatalities. The following year, that number rose to 8%.
Due to its frequency and severity, electrocution is listed among OSHA’s Fatal Four most deadly hazards in construction.
What are the common causes of electrocution?
Electrocution on construction sites is often caused by contact with overhead or fallen power lines, working on energized equipment without proper lockout/tagout procedures, or using tools that aren’t properly grounded.
Other risks include damaged or exposed wiring, faulty equipment, wet conditions near electrical sources, and worn or frayed insulation on cords.
These incidents often stem from a failure to follow basic electrical safety protocols.
How do I prevent electrocution and electric shock?
The best way to prevent electrocution is by sticking to proven safety practices and ensuring everyone on the job is trained and alert. Start by following OSHA electrical safety standards and making hazard recognition a part of everyday work.
Make it a habit to inspect power tools, cords, and extension leads. If you notice frayed wires, exposed insulation, or any kind of damage, don’t use them.
Always turn off the power and follow lockout/tagout procedures. When working near live electricity, make sure you wear appropriate PPE, such as insulated gloves and rubber-soled boots.
What do I do if someone on my job site has been electrocuted?
Quick, safe action can save a life. If someone has been electrocuted on your job site, follow the steps in S.A.F.E.:
- S — Survey the scene
- A — Avoid direct contact
- F — Free the victim from the source
- E — Evaluate and perform CPR
S — Survey the scene
Call 911 and assess the situation. Look for signs of serious injury, such as:
- Severe burns
- Confusion or loss of consciousness
- Difficulty breathing
- Irregular heartbeat or cardiac arrest
- Seizures or muscle contractions
A — Avoid direct contact
Don’t touch the person if they are still in contact with the electrical source; it could also put you in danger.
F — Free the victim from the source
Turn off the power if possible. If that isn’t possible, use a dry, non-conductive object such as wood to separate the person from the electrical source.
E — Evaluate and perform CPR
If the person isn’t breathing or has no pulse, begin CPR immediately and continue until emergency responders arrive.
