About This Item


Full Description

The U.S. population is multi-ethnic, highly mobile, and derived from a multiplicity of social and educational backgrounds, with different reading skills and word comprehension. These factors complicate the effectiveness of word-only signs. Effective safety symbols have demonstrated their ability to provide critical information for accident prevention and for personal protection. Signs with safety symbols can promote greater and more rapid communication of the safety message, and therefore, greater safety for the general population. An initial set of such selected safety symbols is presented here. Methodologies for designing and evaluating safety symbols for additional applications are also presented.

This standard provides general criteria for the design, evaluation, and use of safety symbols to identify and warn against specific hazards, and to provide information to avoid personal injury.

It is the purpose of this standard to promote the adoption and use of uniform and effective safety symbols for safety communications. The standard also provides a procedure for evaluating image effectiveness in communicating the intended message, as well as considerations for graphic design of safety symbols.
