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.

The 2021 edition of NFPA 70E states: An electrical hazard is a dangerous condition such that contact or equipment failure can result in electric shock, arc flash burn, thermal burn, or arc blast. 

 

Safety is a shared responsibility.

OSHA regulations are clear—it is the responsibility of employers to protect employees from electrical hazards, including arc flash.

The 2021 NFPA 70E requires:

  • Employer provide safety‐related work practices and train the employee

  • Employee implement safety‐related work practices

  • Employer documents each employee has received training

  • Employer document employee proficiency and maintain the records for duration of employment – including employees name, training content and training dates

  • Employer responsibility to provide appropriate PPE and ensure employees follow all policies related to energized vs. de‐energized work

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 for how to implement safety in the workplace.

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

The answer is yes.
