Safety Symbols

Both OSHA and ANSI encourage the use of safety symbols whenever useful. If a safety symbol helps to convey a message more quickly and clearly, it should be included on the sign. It is necessary to understand what they are, when they should be used, and where they should be placed on safety signs.

Safety symbols can portray required actions, consequences, explicit direction, or the effects of interaction with certain chemicals, machines, and other hazards. Signs and labels may include more than one pictorial to show a sequence of events for one hazard.

Safety symbols should be consistent, readable, and easily understood. They usually consist of a black image on a white background

When appropriate, you may use a graphic representation that conveys your message without using words. The safety symbol should “describe the type of hazard, or evasive/avoidance actions to be taken” ANSI Z535.2-2007 (8.1.2).

Safety symbols should effectively communicate the message, be easily understood, and be visible from a safe distance. An industrial symbol library of over 400 symbols is included in Graphic Products’ comprehensive software package.
