Why “Arc Flash Safety—Unqualified Person” Matters:

  • According to the National Fire Protection Association more than 2,000 people are treated for severe arc flash injuries each year.
  • On average, five to ten arc explosions occur in electric equipment every day in the United States.
  • Bureau of Labor Statistics data for 1994 show 11,153 cases of reported days away from work due to electrical burns, electrocution or electrical shock injuries, fires, and explosions.
  • Electrical burns, often severe, are a common injury from arc flash incidents.
  • Pressure waves can damage your hearing, fracture ribs, collapse lungs, knock you off a ladder, or blow you across a room.
  • Pressure waves can send loose material like pieces of damaged equipment, tools, and other objects flying through the air at speeds in excess of 700 miles per hour.
  • A high-intensity flash can damage your eyesight and leave you blind.
  • A superheated ball of gas with temperatures in excess of 5,000 degrees that can ignite your clothing and cause serious burns over much of your body.

Key Points:

  • Keep an eye out for arc flash warning labels.
  • Human error is a major cause of arc flash incidents, such as dropped tools, contact with an electrical part, wrong test equipment, and improper work practices.
  • To prevent arc flash, always de-energize and lock out equipment whenever possible.
