Electrical Hazards & Emergency Response Training Short

What determines the severity of an electric shock?

The severity of an electric shock is determined by three main factors: the strength of the electrical current, the path it takes through the body, and the duration of the person's exposure.

Why is working with electricity at height especially dangerous?

Working at height adds danger because an electric shock, even a non-fatal one, can cause an involuntary muscle reaction that leads to a fall, resulting in severe secondary injuries.

What is the mandatory safe clearance distance to maintain from power lines?

You must assume every power line is live and maintain a minimum of a 10-foot distance for yourself and all equipment. This distance increases by four inches for every ten kilovolts over fifty kilovolts.

What is the risk associated with low voltage electricity known as "freezing"?

"Freezing" is when low voltage causes involuntary muscle contractions that prevent a victim from letting go of the electrical source. This condition can lead to longer exposure and serious, continuous injury.

What should I never use to extinguish an electrical fire?

You should never use water to extinguish an electrical fire, as water is an electrical conductor and will make the dangerous situation significantly worse.
