The proposed bill amends Chapter 23-1.1 of the General Laws by introducing a new section titled "Extreme temperatures employee protection." This section defines "extreme temperatures" as those at or above 90 degrees Fahrenheit or at or below 32 degrees Fahrenheit. It mandates that employers develop plans to minimize employee exposure to these extreme temperatures, which must include provisions for paid rest breaks, access to shade, heating or cooling stations, drinking water, and personal protective equipment (PPE). Additionally, employers are required to ensure that supervisors complete a quarterly training program to recognize signs of overexposure and maintain functional heating and cooling equipment.

The bill also outlines specific protections for employees working in vehicles, warehouses, and outdoor settings, requiring adequate insulation and heating/cooling equipment in these environments. Employers must provide quarterly training on temperature safety, covering risk factors, monitoring procedures, and proper use of PPE. The Department of Health is tasked with creating an online tutorial program for supervisors and managers, and any employer who fails to comply with these requirements may face unlawful employment practices. The act is set to take effect on January 1, 2026.
