ANSI Z535.1-2006

Color codes used on safety signs, labels, and tags, as well as for the identification and location of fire extinguishers, first aid kits, traffic aisleways, stumbling and tripping hazards, etc., have been developed in the past by a large number of industrial firms and other organizations.

Although these color codes give satisfaction to those using them, they suffer from lack of uniformity. As a result, spontaneity of action in times of emergency can be lost, particularly by employees who have moved from one plant to another, when each has a different system.

This standard sets forth the specifications and test methods for safety colors in order to establish uniformity of safety color coding.

It is intended that use of this Safety Color Code will supplement the proper guarding or warning of hazardous conditions. The marking of a physical hazard by a standard color warning should never be accepted as a substitute for the reduction or elimination of the hazard wherever possible.
