What is ANSI Z535.1?

ANSI Z535.1 American National Standard for Safety Colors is one of six individual standards that make up ANSI Z535.

ANSI Z535.1 is a standard that describes the color codes that can be used on accident prevention signs, labels, and tags. This also includes the marking and location of first aid equipment, fire extinguishers, trip/slip hazards, and other potential hazards or safety equipment.

ANSI Z535.1 color codes are set for nine colors and their combinations. The use cases for each color are as follows:

Red: fire protection equipment, danger signs, containers of flammable liquids, stop buttons and switches, and lights at barricades

Orange: signs and equipment designating dangerous or energized machines or equipment

Yellow: physical hazards including those concerning falling, tripping, and striking, and designating caution

Green: designates safety information and first aid equipment

Blue: designates information not immediately safety related, such as property or security policies

Black, Grey, Purple, White, and combinations of Black, White and/or Yellow: the use cases of these colors may be defined by the end user

Using ANSI Z535.1 color codes helps to create a unified look for these hazards and equipment, which could help to increase a worker’s recognition of them and increase necessary reaction time to hazards or emergencies.
