Q. Where can I buy high voltage signs that are OSHA and ANSI compliant?

Our high voltage signs are available in aluminum, plastic, and adhesive formats in Danger header red/black/white designs for immediate life-threatening hazards, coming in multiple sizes ideal for electrical panels, utility rooms, substations, and industrial equipment.

Yes, our high voltage signs collection includes engineer-grade and high-intensity reflective aluminum options for outdoor substations, utility equipment, and transmission infrastructure that remain visible at night or under flashlight illumination to help prevent accidental contact with energized equipment.

Q. Can I get a custom high voltage sign with a specific voltage rating or clearance distance?

Yes, our 480 volts sign and other voltage-specific options cover common ratings, while our customizable high voltage sign templates let you specify an exact voltage level, clearance distance, or specific safety instruction in multiple materials and sizes to match your electrical equipment's hazard communication requirements.

Q. What size high voltage sign do I need for an electrical panel or utility room?

For electrical panels a 7x10 or 10x14 inch sign is commonly used, and our electrical closet do not enter high voltage sign is a popular choice for utility room doors, while ANSI guidelines recommend 25 feet of viewing distance per inch of text height to determine the right size for larger equipment or longer viewing distances.
