A Danger sign is red and marks an imminent hazard that will cause death or serious injury if not avoided. A Warning sign is orange and marks a hazard that could cause death or serious injury. A Caution sign is yellow and marks a hazard that could cause minor or moderate injury. Match the header to how severe and how likely the hazard is.
They are warning signs and labels built to the ANSI Z535 standard so the same hazard reads the same way in any facility. Standardizing the header, color, symbol, and layout means a worker learns the system once and understands every sign after that. Use rigid warning signs for areas and equipment, and peel-and-stick warning labels for machines, panels, and products.

A road warning sign follows the federal MUTCD and is a yellow diamond with a black symbol, used for traffic. This page covers ANSI workplace warning signs. For yellow-diamond traffic signs, look to road and traffic signage instead.

Yes. Our glow projecting warning sign is 40-mil aluminum with a Glo Brite photoluminescent film on the face. It needs no electricity or battery. It absorbs natural or artificial light during the day and glows in the dark, so it works indoors and outdoors, and it keeps warning during a power outage.
