Electrical Hazard Signs FAQs
What OSHA standard applies to electrical hazard signs?
OSHA 29 CFR 1910.303 requires adequate warning signs on electrical equipment. NFPA 70E sets the standard for arc flash hazard warning labels, which must include flash protection boundary, incident energy level, and required PPE.
What is an arc flash label and when is it required?
An arc flash label is required by NFPA 70E on electrical equipment that poses an arc flash hazard. It must display the arc flash boundary, incident energy at working distance, required PPE category, and shock hazard voltage.
What voltage level requires a high voltage sign?
OSHA considers voltages above 600 volts as high voltage. However, NFPA 70E recommends shock hazard warnings for all exposed energized parts above 50 volts.
Are electrical signs available in aluminum?
Yes. Aluminum is our most popular material for electrical hazard signs due to its durability, corrosion resistance, and ability to withstand industrial environments. Adhesive vinyl is available for labeling panels and equipment enclosures.
Can I get custom arc flash labels with specific incident energy data?
Yes. Our custom label tool allows you to input specific arc flash boundary distances, incident energy values, and PPE categories to create NFPA 70E-compliant arc flash labels for each piece of equipment.
