Arc flash labels warn of the risk of an arc flash event at electrical equipment, and where required, identify the incident energy level and PPE category needed before approach or work. Arc flash hazards are distinct from a general shock or voltage hazard because of the explosive thermal and pressure event an arc flash can produce.
Arc Flash Safety Labels are an important component in preventing arc flash hazards. NFPA 70E sets requirements for labelling of potential electrical arc flashes, for any equipment that may be serviced, examined, adjusted, or maintained while energized.
Governed by NFPA 70E (Electrical Safety in the Workplace), which defines arc flash risk assessment and labeling requirements. This standard was developed to assist with OSHA 1910 and OSHA 1926 compliance.
3M polyester base with polyester overlaminate, UL Recognized and CSA Approved, rated –40°F to 300°F for indoor and outdoor use. Full construction details are on the Label construction page.
OSHA does not mandate a specific label format directly, but NFPA 70E — widely adopted as the electrical safety standard — requires arc flash labeling on equipment covered by a risk assessment, and OSHA references NFPA 70E in enforcement.
