What is ANSI Z535.4?

ANSI Z535.4 American National Standard for Product Safety Signs and Labels is one of six standards that make up ANSI Z535.

This standard presents a single, cohesive system for the display of safety information on signs and labels, complementing ANSI Z535.2, Z535.5, and Z535.6 and used in conjunction with all other ANSI Z535 standards.

ANSI Z535.4 is the standard that utilizes the other standards to promote the best practices of designing and selecting safety signs and labels in your workplace. The goal of ANSI Z535.4 is to incorporate the use of signal words, safety colors, sign layout, letter styles, and the use of symbols into a unified code for the identification of hazards via safety signs and labels. For an overview of the specific elements of a safety label that this standard covers, see our ANSI Z535.4 Safety Labels page.

ANSI Z535.4 also addresses formats promoted by the International Organization of Standards along with durability and maintenance expectations of signs (the International Organization of Standards is an organization similar to ANSI in its goals of promoting universally accepted standards).

When these design elements are brought together under ANSI Z535.4, the uniform design helps to reduce variation in safety identification, reducing reaction time and increasing the awareness of hazards for workers.

What are ANSI standards?

ANSI is an independent organization that oversees standards for numerous industries. These standards help create uniformity for products, processes, and ways to share information, such as accident prevention information. Learn more here.

Do I need OSHA or ANSI safety signs?

The goals of OSHA and ANSI designed signs are the same: to alert workers of potential hazards and of workplace polices. There are many factors that should be considered before choosing one design or the other, and in many cases, an ANSI formatted sign will comply with OSHA standards. Learn more here.

What is ISO?

The International Organization for Standardization (ISO) in an organization similar to ANSI, which oversees, creates, and promotes internationally accepted standards. Learn more here.
