What is an Arc Flash Study?

An arc flash study (sometimes called an arc flash analysis or a hazard analysis) is an on-site study of a workplace facility, conducted by a trained expert qualified to evaluate the electrical system and suggest areas presenting risk to personnel and/or equipment. The arc flash study provides a report containing suggestions and instructions for keeping your workers safe and improving and maintaining electrical systems. The report offers recommendations for personal protective equipment (PPE) for employees, and suggests adjustments to reduce workforce exposure to arc flash hazards.

OSHA 1910.132(d) requires employers to "assess the workplace for hazards." Arc flash is one of the electrical hazards recognized by OSHA and NFPA 70E. The NFPA 70E requires an arc flash hazard analysis calculation be performed with the only exception being use of 70E tables, if you meet the table parameters. It often requires an engineering evaluation to determine if you can use the tables.
