What is Arc Flash?

Arc Flash is the result of a rapid release of energy due to an arcing fault between a phase bus bar and another phase bus bar, neutral or a ground. Since this sudden release of energy can be extremely destructive and potentially fatal, OSHA requires arc flash analysis for all electrical equipment including meter sockets, switch or breaker panels, fuse panels, MCC’s, hard wired disconnects, machine control disconnects, and any panel likely to be serviced by a worker while energized.

A comprehensive Approach to NFPA 70E – Arc Flash Compliance Service Should Include the Following:

  1. A facility must provide, and be able to demonstrate, a safety program with defined responsibilities.
  2. Calculations for the degree of arc flash hazard.
  3. Correct personal protective equipment (PPE) for workers.
  4. Electrical training for qualified personnel on the hazards of arc flash.
  5. Appropriate tools for safe working.
  6. Warning labels on equipment.

Why act now?

Arc flash can be an extremely destructive and fatal release of energy and must be taken seriously.  While working live should always be a last resort, circuits must be assumed live until verified fully deenergized – a critical step to the lockout/tagout process.  Arc flash accidents result in devastating consequences to the workers involved and their families.  The accidents are also very damaging to the equipment and costly to the employer and its insurers.  The average cost of a single survived accident can easily reach $8-10 million in direct and indirect costs.  Legal settlements almost always involve citations of deficiencies in the employer’s safety program as a causative factor leading to the accident.
