OSHA
The Occupational Safety and Health Administration (OSHA 1910.145) requires the use of safety signs to indicate and define specific hazards that, without identification, may lead to accidental injury to workers and/or the public or to property damage.

ANSI Z535
The ANSI Z535 Committee on Safety Signs developed a set of standards for the design, application and use of signs, colors, and symbols intended to identify and warn against specific hazards and for other accident prevention purposes. The recommended format is intended to provide a safety alert message that is clearly and rapidly understood. Lettering is left justified, as well as upper and lower case to enhance legibility, and internationally recognized pictograms are used for universal comprehension.

ALERT
As our workforce becomes more global and diverse, visual forms of communication are relying more and more on the use of symbols and pictograms to warn about hazardous conditions. By using internationally recognized pictograms, Alert signs help you promote greater and more rapid communication of safety messages. (Alert signs do not comply with the ANSI Z535 standard).

BLANK
Blank signs allow you to create your safety message without a header. Pictograms may be added to the right side of the sign (see Alert sign style) to help communicate warnings.
