When electrical equipment must be maintained or repaired while energized, an arc flash hazard may be present. Affected workers need to know what steps should be taken to stay safe. Arc flash warning labels can provide this information, right where and when it’s needed. As a result, experts in electrical safety recommend using standardized and helpful arc flash labels.
The most referenced standard for creating arc flash labels is NFPA 70E: Electrical Safety in the Workplace. While OSHA does not explicitly require employers to follow it, OSHA has used NFPA 70E as an example of recognized industry practices when evaluating a facility’s electrical training, procedures, and signage, especially when it comes to arc flash.
