Arc Flash and Welding Arc Signs

Arc flash signs are required by NFPA 70E and the NEC to warn workers of arc flash hazards that can cause severe burns or death, and our arc flash signs protect personnel working near energized electrical equipment and serve as a specialized subset of high voltage signage that clearly identifies arc flash boundaries and shock hazard zones on panels and switchgear.

A label must show system voltage and the Arc Flash Boundary. For medium-risk hazards, these often utilize the layout found in our ansi warning signs.

Arc flash signs are placed on switchboards, panelboards, and motor control centers where energized electrical hazards are present, and our electrical panel signs and arc flash signs are commonly paired with our authorized personnel only sign to reinforce access restrictions and protect workers from life-threatening electrical hazards in these high-risk areas.

Yes, "Write-On" labels allow a qualified person to manually enter calculated values. For a more permanent and professional look, you can also use our custom ansi signs tool.
