![]() Toxic Fumes: The release of plasma is a very serious hazard when inhaled causing burns inside of the body. ![]() ![]() It can also knock people over, break objects and send shrapnel flying. Pressure: The massive wave of pressure from an arc blast can cause internal injuries like collapsed lungs and ruptured eardrums.Ultraviolet Radiation: A flash of UV radiation can briefly blind and disorient you and can cause severe eye injuries.It can also vaporize or melt metal objects, releasing toxic vapors into the air. Temperature: An arc flash can reach extremely high temperatures of up to 35,000℉ in a fraction of a second. This comes with effects like severe burns and the combustion or melting of materials such as clothing, even when standing several feet away.What Are the Dangers of Arc Flashes?Īrc flash events are a very serious hazard, with several components that can cause injuries, damage, fire, and death: When this type of electric arc occurs, they turn into an arc flash event, also known as flashover. A very brief, abrupt electrical arc is called a spark, this would be extinguished before an arc flash can occur but if it continues due to a large supply of electric current, it is considered an electric arc. When this happens, the arc flash creates plasma, resulting in dangerous levels of light, heat, pressure, and sound. Table of ContentsĪn electrical arc occurs during an electrical fault when very high levels of current flow between two live conductors. Commercial facilities must take careful measures to prevent arc flash events and protect employees. This dangerous occurrence generates a massive release of energy in the form of, heat, toxic fumes, blinding light, deafening noise and massive pressure waves. An arc flash is one of the most prominent safety concerns for those who work with or around electricity.
