Why Safety Colors – and ANSI Z535.1 – Matter

Posted by Clarion Safety Systems | 13th Jul 2023

The colors used in your safety labels and safety signs are one of their building block components. To use them effectively in your warnings and instructions – and to implement them in line with today’s best practices – one specific standard stands out: ANSI Z535.1. Keep reading to learn more about how to use safety colors across your machinery and workplace in line with ANSI Z535.1, straight from your team of experts at Clarion Safety!

What is ANSI Z535.1?
ANSI Z535.1 is an American National Standards Institute (ANSI) standard that provides guidelines for the use of colors in safety signs, labels, tags, and markings to communicate hazards and safety information. It establishes a set of color codes and specifications that help convey safety messages clearly and consistently across different industries and applications.

Why Do Safety Colors Matter?
“Effectively communicating hazards is vital for safety. The use of color can help with comprehension and understanding of safety messages, but it has to be very specifically defined. The orange used in a warning label’s signal word panel has to look like orange. It can’t look like ‘yellowish orange’ or ‘reddish orange’. It’s important to avoid, at a glance, having that color be confused with yellow (which is used in signal word panels for caution situations) or red (which is used in a signal word panel for danger situations),” says Angela Lambert, our head of standards compliance at Clarion Safety Systems.

“ANSI Z535.1 safety colors are tightly defined and should be adhered to for proper color discrimination or color coding. The science behind colors and color stability are an important part of effective communication on equipment safety labels and facility safety signs.”
