What are the 4 main types of electrical injuries?

There are four main types of electrical injuries: flash, flame, lightning, and true. Flash injuries, caused by an arc flash, are typically associated with superficial burns, as no electrical current travels past the skin.

What are common hazards when working with electricity?

Ladders & Electrical Lines

When using ladders, high-lows, cherry pickers, and other equipment that goes high into the air, it is necessary to take strong precautions to avoid bumping into any electrical wires. Even simply carrying a ladder vertically can often run into these types of wires, resulting in electrocution.

How does electricity exit the body?

So-called entry and exit wounds

These terms relate to the fact that electric current comes from a voltage source, enters the body at one point, flows through the body to the other contact point, where it exits the body, and returns to the voltage source (or a ground).
