Three updated ANSI Z535 standards available, with four more to come
The American National Standards Institute (ANSI) approved three of six standards in the Z535 series of consensus standards on June 2, and the 2022 editions are now available for purchase. ANSI standards are generally revised every five years, so the updates are on time, as the latest standards replace the 2017 editions.
Note that the National Electrical Manufacturers Association (NEMA), the Secretariat of the ANSI Z535 series, explains that three more standards in the series are slated for update and publication in 2022, and a new standard is also anticipated.
What are the changes?
Here’s a list of the standards that updated along with a summary of the changes:
- ANSI Z535.1-2022, American National Standard for Safety Colors — This standard focuses on color tolerances for 10 safety colors: red, orange, yellow, green, blue, black, white, purple, brown, and gray. For 2022, minor updates align the standard with the other Z535 standards. Clarifications are also made to explain how Z535.1 relates to other standards/regulations.
- ANSI Z535.3-2022, American National Standard for Criteria for Safety Symbols — This standard goes over the design and use of safety-related symbols. It recommends symbol designs that are consistent, legible, understandable, simple, and representational. For 2022, you’ll find updated symbols in Annex A and a new caveat added to Annex C1 Scope about variant references. Multiple choice is no longer a test method in this edition when considering symbol comprehension.
- ANSI Z535.5-2022 American National Standard for Safety Tags and Barricade Tapes (for Temporary Hazards) — This standard covers the design of temporary safety tags and barricade tape. It also discusses their application and use. For 2022, the standard has updated references and minor clarifications. Further clarifications are made to explain how Z535.5 relates to other standards/regulations.
More changes coming this year
The remainder of the ANSI Z535 series listed below are anticipated to be revised later this year, but a summary of upcoming changes is not yet available:
- ANSI Z535.2, American National Standard for Environmental and Facility Safety Signs — This standard covers the design of safety signs. It also discusses their application and use.
- ANSI Z535.4, American National Standard for Product Safety Signs and Labels — This standard focuses on the design of product safety signs and labels. It also discusses their application and use, as well as placement.
- ANSI Z535.6, American National Standard for Product Safety Information in Product Manuals, Instructions and Other Collateral Materials — This standard goes over the design of safety-related messages for product manuals and materials. It also discusses their location.
A new, yet-to-be-named ANSI Z535.7, which is also in the works, is projected to cover product safety information shown in electronic media.
How do the updates relate to OSHA compliance?
Technically, these ANSI Z535 series changes do not directly impact federal OSHA compliance. That’s because OSHA currently adopts older 2011 editions of ANSI Z535.1, .2, and .4. Until OSHA issues a final rule to adopt later versions of the ANSI Z535 series, employers are required to adhere to the older editions, as referenced in 29 CFR 1910.145 for general industry and shipyards and 29 CFR 1926.200 for construction.
However, OSHA adds that an employer is allowed to comply with the most current consensus standards (like ANSI) applicable to its operations, rather than with the OSHA regulation in effect, when its action provides equal or greater worker protection. So long as the followed consensus standard provides such protection, a violation where the employer is not literally in compliance with OSHA’s regulation may be considered “de minimis” — a technical violation carrying no penalty.
Therefore, if an employer can demonstrate that the later ANSI Z535.1, .2, and/or .4 standards that it follows provide equal or greater worker protection than 1910.145 or 1926.200 (depending on the industry), that employer may follow those ANSI standards and only risk a de minimis violation during an OSHA inspection of a general industry, shipyard, or construction operation.
Key to remember
Three of the ANSI Z535 standards are updated, with more updates and one addition to come. The ANSI Z535 series changes do not directly impact federal OSHA compliance until that agency issues a final rule to adopt the latest editions.
