An electrical hazard can result in which injuries?

• A. Electric shock
• B. Arc blast injury
• C. Thermal burn
• D. Electric shock, arc flash burn, thermal burn, or arc blast injury

Answer: (D)

Electrical hazards can produce a variety of injuries, not just one outcome. Electric shock happens when current passes through the body. An arc fault can cause an arc flash, delivering intense heat, light, and energy that can burn skin or ignite clothing. The rapid air expansion from that arc—the arc blast—creates a pressure wave and can throw objects, causing injury. Thermal burns can come from contact with hot equipment or from the heat released by an arc. Because a single electrical hazard can cause all of these injury types, the most complete choice includes electric shock, arc flash burn, thermal burn, and arc blast injury. The other options only mention one or two injuries and miss the others.
