For electrical workplace safety, the key to staying safe is following the National Fire Protection Association standard NFPA 70E Electrical Safety in the Workplace. It’s your responsibility to read and fully understand this standard. To protect you from the heat of an arc flash, the NFPA has established four PPE categories numbered by severity from 1-4.
Requirements for personal protective equipment are generally based on the amount of available short-circuit current and fault clearing time. The following video provides more context, to help you get started implementing NFPA guidelines.
