Course Overview

When an electric current passes through air between ungrounded conductors or between ungrounded conductors and grounded conductors, temperatures can reach levels as high as 20,000°C (35,000°F). Exposure to these extreme temperatures burns the skin directly and ignites clothing, which adds to the burn injury. The majority of hospital admissions due to electrical accidents are from arc flash burns, not from shocks. Each year more than 2,000 people in the United States are admitted to burn centres with severe arc flash burns. Arc flashes can kill at a distance of 3 meters (10 ft).
