ISA is pleased to share that the Z133-2026 Safety Standard has been approved by ANSI and is now available.

The American National Standard: Safety and Health Requirements for Arboricultural Operations (commonly referred to as the Z133 standard) is a United States safety standard for use across the arboriculture industry. The previous edition of the Z133, effective until 27 May 2026, was published in 2017. Since that year, the Z133 Committee has drafted revisions to refine the standard, ensure better safety outcomes, and keep pace with developments in the industry.

The Z133 standard is available through the ISA web store in English and Spanish with digital and print options.
