Arc Flash Hazards

An Arc Flash is a massive energy discharge–causing a very high-pressure, high-heat arc blast capable of melting metal and devastating everything in its path. The electrical arc is caused by either a phase to phase fault or a ground to phase fault–the result of workplace negligence such as improper installation or procedures; or an accidental incident such as dropping a tool, contacting energized components, or equipment failure. An arc flash can result in minor injuries, third degree burns, blindness, hearing loss, nerve damage, cardiac arrest, and often death.

OSHA regulations are clear—it is the responsibility of employers to protect employees from electrical hazards, including arc flash. OSHA defines the regulation, but doesn't specify how to comply. That’s where NFPA 70E comes in. NFPA 70E is the industry standard—the go-to “best practices” guide forhow to implement safety in the workplace.

Visit our Arc Flash website and learn more about how an Arc Flash Risk Assessment (formerly known as Arc Flash Hazard Analysis) can protect your workers and your facility, and satisfy compliance regulations.

Maybe you’ve already asked yourself: “Can I be cited for failing to comply with NFPA 70E?”

The answer is yes.
