While the intent here was to introduce arc flash/blast information and make aware the dangers involved with servicing electrical equipment, it is not intended to intimidate the worker, but instill a healthy sense of respect for the power of electricity. Through proper training, equipment maintenance, selection of the appropriate PPE, safety regulations and programs, the electrical technician should have gained the confidence that they have the tools at their disposal to perform the task at hand safely.

  • Arc flash is something you cannot see, hear, feel, smell, or taste it before it happens.
  • Don't need to fear electricity, but you do need to respect it.
  • Arc flash impacts you financially – loss of time/medical bills/possible long term recovery or disability.
  • Arc flash impacts you, your family, friends, and co-workers emotionally.
  • PROTECT YOURSELF – Remember, ultimately we are responsible for our own safety.
