Electrical Hazards – High-Voltage Electrical Burns Electrical contact can cause some of the most severe injuries encountered in the workplace. Electrical injuries may include shock, electrical and thermal burns, arc-flash injuries, cardiac arrest, internal tissue damage, falls, and electrocution. Electrical burns can be particularly dangerous because the injury visible on the skin may represent only a small portion of the actual damage. Why Electrical Burns Are So Serious When electrical current passes through the body, damage may occur at the point of contact, along the current's path through the body, and at another point where the current exits. Electrical injuries may cause: Deep muscle, nerve,...

Avoiding Electrical Shock Electrical hazards exist in nearly every workplace. Contact with electricity can cause shock, severe burns, muscle contractions, falls, heart disturbances, and electrocution. Because electrical hazards are not always visible, employees should treat electrical equipment and circuits with caution and never assume they are safe. Electrical current can travel through the body when a person contacts an energized conductor while also providing a path to ground. Even relatively small amounts of current passing through the chest can interfere with normal heart and respiratory functions. Protect Yourself from Electrical Shock Follow these basic precautions when working with or around electrical equipment: Inspect before...
