ANSI Z35.1 the Specifications for Accident Prevention Signs, was an American standard that dictated the layout, colors and wording of safety signs in the United States. The standard is the first American standard that made specific demands for the design, construction, and placement of safety signage in industrial environments. The first edition was published in January 1941, and the fourth and final edition in November 1972. Changes in societal needs of signage, and further research into signage would result in the establishment of a new committee, the ANSI Z535 Committee on Safety Signs and Colors, combining the separate committees of Z35.1 - Specifications for Accident Prevention Signs, Z35.2 - Specifications for Accident Prevention Tags, and Z53 - Marking Physical Hazards Safety Color Code, resulting in a new combined standard, ANSI Z535.
