Arc Flash Hazard Analysis

An Arc Flash incident is an explosive release of energy caused by an electrical arc due to a phase to ground or phase to phase fault. Arc flashes can and do kill at distances up to 10 feet. The main reason to have an Arc Flash Hazard Analysis performed for your facility is SAFETY. JDRM Engineering can help employers protect their employees from electrical hazards.

JDRM can provide customized arc flash hazard labels.

When are facilities required to have an arc flash hazard analysis performed?

OSHA requires that a workplace hazard assessment has been performed through a written certification. NFPA identifies Shock and Arc Flash as electrical hazards that need to be assessed at all facilities. An arc flash hazard analysis should be performed if any employee could be exposed to live parts above 50V or if abnormal operating conditions occur to electrical equipment.

When should your organization or facility update your Arc Flash Study?

Following the NFPA 70E guidelines, “The incident energy analysis shall be updated when changes occur in the electrical distribution system that could affect the results of the analysis. The incident energy analysis shall also be reviewed for accuracy at intervals not to exceed 5 years.” Accordingly, JDRM Engineering minimally recommends updating your Arc Flash Study as soon as your next updates are scheduled.
