Arc Flash Hazard Analysis

Arc flash safety is an important consideration for any commercial or industrial facility. Not only is it a good idea to have knowledge about one’s power distribution system, the Bureau of Labor Statistics records more than 2,000 injury incidents a year that require admission to a burn care center from the result of an energized, electrical accident. This statistic alone suggests energized, electrical equipment is dangerous and the proper precautions must be taken to minimize the risk in these areas.

Arc flash is a short circuit through the air that releases heat of up to 35,000 degrees with effects being compounded by the tight, enclosed areas where many electrical components are located. The effects of an arc flash from a even a moderate electrical supply can cause severe injury including severe burns or death.

An Arc Flash Hazard Assessment is part of a complete electrical hazard assessment required by OSHA and NFPA 70E.

Arc Flash Can Be Caused By

  • Coming close to a high-amp source with a conductive object
  • Dropping a tool or otherwise creating a spark can ignite an arc flash
  • Equipment failure
  • Breaks or gaps in insulation
  • Dust, corrosion or other impurities on the surface of the conductor

Equipment that must be properly analyzed and labeled includes

  • Switchboards
  • Panelbaords
  • Industrial control panels
  • Meter socket enclosdures
  • Motor control centers
  • Disconnects

…or any electrical component that requires maintenance, inspection, or adjustment.
