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 the 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.
KEY ELEMENTS
- Hazard assessment to assess workers exposure to heat stress
- Identification of on-site engineered and administrative controls
- Designated shade areas for breaks
- Scheduled mandatory rest breaks
- Identification of proper cooling PPE to reduce risks
- Requirements to provide portable water and electrolytes to employees
- Methods to acclimatize new and returning workers to heat stress environment
- Identification of employee participation and responsibilities
- Methods to monitor workers heat strain, preferably through a buddy system approach
- Heat stress training on policies and procedures related to heat illness prevention
- Development of an emergency action plan for heat-related emergencies
While this standard sets best practices, it remains voluntary. It’s important to note that OSHA’s Heat Stress NEP does legally require employers to develop and implement heat illness prevention programs. With the release of this standard, ANSI has provided an expert developed standard for employers to follow and ensure OSHA compliance.
