Full Description
The U.S. population is multi-ethnic, highly mobile, and derived from a multiplicity of social and educationalbackgrounds, with different reading skills and word comprehension. These factors complicate theeffectiveness of word-only signs. Effective safety symbols have demonstrated their ability to providecritical information for accident prevention and for personal protection. Signs with safety symbols canpromote greater and more rapid communication of the safety message, and therefore, greater safety forthe general population. An initial set of such selected safety symbols is presented here. Methodologiesfor 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 identifyand 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 symbolsfor safety communications. The standard also provides a procedure for evaluating image effectiveness incommunicating the intended message, as well as considerations for graphic design of safety symbols.
