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, which is updated periodically. 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, or PPE, are generally based on the amount of available fault current and fault-clearing time. One technique is to use the “Table Method” in the NFPA 70E standard.
The following video covering the 2018 standard provides more context to help you get started implementing NFPA guidelines.
