High voltage signs use a Danger header with a red, black, and white color scheme per OSHA 1910.145, and our high voltage sign follows this required color standard with the lightning bolt symbol in a bold design for maximum visibility and hazard recognition.

Q. Are there reflective high voltage signs for outdoor electrical 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.
