Electrical Hazard Warning Labels

OSHA 29 CFR 1910.335 requires that electrical panels be clearly marked with warning labels indicating shock and arc flash hazards. Labels must identify voltage levels, use signal words such as DANGER or WARNING, and comply with NFPA 70E standards for arc flash boundaries and PPE categories. Labels must be legible, durable, and permanently affixed to the equipment.

Shield and Supply's electrical hazard warning labels are available in vinyl, reflective, high-temperature, and metallic materials. Vinyl labels offer scratch and chemical resistance with a 5–10 year lifespan, while high-temperature options are ideal for environments near heat-generating electrical equipment. All materials are engineered for long-term adhesion indoors and outdoors.

Electrical hazard warning labels are available in yellow, white, black, red, orange, and other standard OSHA-compliant colors. Yellow and black are the most common for electrical warnings, while orange signals are used for energy source lockout points. Hi-Vis and reflective options are also available for low-light or high-traffic environments.
