The Power of an Arc Blast

Four times the power of the sun. That’s how hot an arc blast can be. Imagine what that kind of heat and flames can do to anyone near an electrical arc flash.

The statistics for an arc explosion are eye-opening:
NFPA book

  • 30,000 arc flash incidents per year
  • An estimated 400 people die each year an arc explosion.
  • Arc flashes injure 5 to 10 people each work day.
  • 80% of all electrical injuries are burns caused by clothes igniting from arc flashes.
  • An estimated 2,000+ go to burn centers yearly for electrical burn injuries.
  • An arc flash can kill at10 ft. away.
  • Electrical blasts produce temperatures as high as 35,000
  • An estimated 500 people die annually from low voltage (120 volts) shocks.

Besides the devastating human toll that an arc flash can bring, the cost and liability to businesses are huge. The National Fire Prevention Association (NFPA) addresses the dangers of arc explosions in their 70E guidelines.

Adhering to NFPA 70E guidelines, the standard for electrical safety, can save lives and prevent injuries from arc explosions.
