About This Item


Full Description

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. As a result, the safety colors are the same as those used with:

American National Standard for Environmental and Facility Safety Signs, ANSI Z535.2-2002;
American National Standard for Criteria for Safety Symbols, ANSI Z535.3-2002;
American National Standard for Product Safety Signs and Labels, ANSI Z535.4-2002;
American National Standard for Accident Prevention Tags (for Temporary Hazards), ANSI Z535.5-2002;
American National Standard Scheme for the Identification of Piping Systems, ANSI A13.1 (1985);
American National Standard Radio Frequency Radiation Hazard Warning Symbol, ANSI C95.2 (1982) (R 1999);
The Department of Transportation (DOT) Hazardous Materials Warning Labels and Placards; and the
National Highway Traffic Safety Administration (NHTSA, DOT) Ambulance Orange and Ambulance Blue.

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.
