Arc Flash Studies
Arc flash incidents are highly concentrated radiant thermal energy resulting from an arcing fault between two points. These potentially devastating events kill or injure people every day. An up-to-date arc flash study helps mitigate these hazards by calculating the limited and restricted approach boundaries inside which workers must use appropriate personal protective equipment (PPE).

- Q
- What is an arcing fault?
- A
- An arcing fault is the flow of current through the air between phase conductors or phase conductors and neutral or ground.
- Q
- What causes an electrical arc?
- A
- An arc occurs when electric current flows between two or more separated energized conducting surfaces. Some arcs are caused by human error including dropped tools, accidental contact with electrical systems, and improper work procedures. Another common cause of an arc is insulation failure.
- Q
- What can happen if I am exposed to arc flash?
- A
- Exposure to an arc flash frequently results in a variety of serious injuries, and in some cases, death. Workers have been injured even though they were 10 feet or more away from the arc center.
- Q
- What can I do to reduce my risk to arc flash exposure?
- A
- Preventive maintenance, worker training, and an effective safety program can significantly reduce arc flash exposure.
- Q
- Are all arcs equal?
- A
- No. You must conduct a hazard assessment to determine the level (intensity) of energy from the arc in calories. Then you can determine the proper personal protective equipment (PPE) needed.

Inherent dangers exist with the operation, maintenance, and repair of electrical equipment. Electrical hazards such as arc flash and arc blast can result in serious injury or death to electrical workers. With proper training, your employees are prepared to protect themselves, their co-workers, and your critical infrastructure.
If your facility is like most, equipment and loads are continually added or removed in small increments, constantly changing your electrical infrastructure. The impact of these changes is not always apparent until some part of the system becomes overloaded or exhibits other problems. Keeping your single-line diagram up to date provides a road map that enables proper protection and system reliability, and is necessary for NFPA 70E compliance.
