Is labeling necessary?

OSHA provides generalized standards for safety labeling, but does not necessariliy state specific requirements for arc flash labeling. ANSI standards also outline hazard identification labeling requirements, but do not call out electrical more than other safety hazards. It is important to understand that proper labeling of safety hazards often means following generalized safety standards and customizing them to your particular arc flash hazard.

OSHA and ANSI Best Practices

OSHA 29 CFR, 1910 clearly outlines regulations for hazard communication. Labeling of hazards is regulated in many hazardous environments, including environments where electrical, chemical or other hazards may impact safety. A proper arc flash warning label should have a clearly visible color bar, preferrably bright orange, with the appropriate warning or hazard sign (often the word "WARNING" accompanied by a triangular "!" symbol). The label should inform the viewer of the presence of an arc flash hazard, including information on hazard boundaries and PPE. It is critical that the label be durable and long-lasting enough to hold up to harsh conditions.

Proper Arc Flash Label

This image represents a proper arc flash label. The orange header bar is clear and easily visible from a distance. The text may vary depending on your arc flash hazard and analysis, but the label should always be easily recognized as a warning label, even from a distance.
