Note for user:
The American National Standard for safety colors describes in general the self defined data for the basic colors according to Munsell: Red, Orange, Yellow, Green, Blue and Purple. Safety White and Safety Black are also described, but are listed seperataly in an own chart. Safety Brown and Safety Gray have been excluded from the standard, because they are not considered anymore safety colors for accident prevention. ANSI works systematically and describes in the preface the method of defining the safety colors. The terminology and the technical terms are also described in order to make the standard easy to understand for users not familiar with safety colors. In contrast to the edition of 2006 a lot of definitions have been implemented into the standard. In order to illustrate the colors in a understanding way, they were listed in a chart and described with those parameters: Color, Munsell notation, CIE data*. The charts and figures were revised and partly replaced. Some new ones have been added as well.
The standard has the scope to form a uniform system for the specification of safety colors and to harmonise with the ISO 3864-4. That standard describes the color and photometric attributes of supporting materials for safety signs and labels. Also the formulas for specific systems are given and displayed in the Annex. Those formulas are provided from the Pantone, Munsell, RAL, NCS and BS System. Additional you can find the data for the cmyk, RGB and HTML numbers so you can work with the colors also digitally.
Please note: The mentioned safety colors are opaque surface colors, they are not fluorescent nor phosporescent.
Note: The standard is only available in English.
