A tremendous amount of heat is generated when arcing faults occur. This can be extremely
hazardous to personnel working on or near the location where the fault happens.
The number one reason to be concerned about arc flash is for the safety of these personnel.
Arc Flash Hazard Studies are performed to determine the risk to personnel, warn them of the hazards,
and to instruct them as to what kind of personal protective equipment (PPE) they must wear.
Another reason to be concerned about Arc Flash Hazards is liability and government
regulations. OSHA regulations apply to every worker that may approach or be exposed
to energized electrical equipment. Failure for an employer to conform and follow OSHA
and NEC requirements can lead to employee injuries, fines, penalties, and expensive law suits.
There are several regulations that address arc flash hazards. They are:
- National Fire Protection Association (NFPA) Standard 70 or better known as The National Electric Code.
- The NEC® 2002 addresses the arc flash hazard in Article 110.16.
- NFPA 70B 2002 Recommended Practice for Electrical Equipment Maintenance.
- NFPA 70E 2000 Standard for Electrical Safety Requirements for Employee Workplaces.
- OSHA Standards 29-CFR, Part 1910 Sub part S (electrical) Standard number 1910.333.
