ANSI/ASSP released the new, voluntary standard A10.50-2024 on Feb 26 of this year which outlines the key elements for Heat Stress Protection in Construction and Demolition. The purpose of this standard is to reduce the risk to workers to heat stress due to heat exposures in construction and demolition operations. According to theĀ U.S. Bureau of Labor Statistics, more than 400 workers have died of heat exposure since 2011. It establishes the minimum requirements for preventing heat illnesses and the management of heat stress hazards.

With the release of this standard, ANSI has provided an expert developed standard for employers to follow and ensure OSHA compliance.
