The Definition of Electrocution

Electrocution refers to a fatal injury caused by an electric current passing through the human body, typically disrupting the heart's normal rhythm or causing severe internal and external burns. Electrocution can occur from direct contact with live electrical components, contact with equipment that has become energized due to a fault, or proximity to high-voltage power lines. The severity of an electrical injury depends on factors such as the voltage and current involved, the path the current takes through the body, and the duration of contact, which is why even seemingly low-voltage sources can be fatal under certain conditions.

Example of Electrocution

A worker operating a metal ladder near an overhead power line contacts the line while repositioning the ladder, resulting in a fatal electrocution; the incident investigation leads the company to establish strict minimum approach distances for any work performed near energized power lines.

Frequently Asked Questions: Electrocution

What factors determine the severity of an electrocution injury?

Severity depends largely on the amount of current that passes through the body, the path it travels, such as whether it crosses the heart, and how long the contact lasts, with even relatively low currents posing serious risk under certain pathways and durations.

How can workplaces prevent electrocution near power lines?

Workplaces can prevent electrocution by establishing and enforcing minimum safe approach distances from energized lines, using non-conductive equipment near power lines, and coordinating with utility companies to de-energize or reroute lines before work begins nearby.

What should be done immediately if a coworker is being electrocuted?

The electrical source should be shut off or the person separated from it using a non-conductive object before any physical contact is made, since touching someone still in contact with a live source can result in electrocution of the rescuer as well.
