b. The arc flash boundary

c. The PPE to be used within the arc flash boundary

(2) Be updated when a major modification or renovation takes place. It shall be reviewed periodically, at intervals not to exceed 5 years, to account for changes in the electrical distribution system that could effect the results of the arc flash risk assessment.

(3) Take into consideration the design of the overcurrent protective device and its opening time, including its condition of maintenance.

 NFPA 70E 2012 Article 130.5

NFPA 70E

The arc flash hazard analysis shall be updated when a major modification or renovation takes place. It shall be reviewed periodically, not to exceed 5 years, to account for changes in the electrical distribution system that could affect the results of the arc flash hazard analysis.

The arc flash hazard analysis shall take into consideration the design of the over current protective device and its opening time, including its condition of maintenance.

Should an Arc Flash accident occur in your facility resulting in bodily injury or death OSHA would investigate the incident to determine whether or not your facility was in compliance or not. If they find that you are out of compliance not only will you be liable for the accident but will likely be shut down until compliance is reached. The business owner and person(s) liable for the safety would also be subject to heavy fines and possible incarceration.
