The bill amends Chapter 23-1.1 of the General Laws by introducing a new section titled "Extreme temperatures employee protection." It defines extreme temperatures as those at or above 90 degrees Fahrenheit or at or below 32 degrees Fahrenheit. Employers are mandated to implement plans to prevent and reduce employee exposure to these extreme temperatures, which include providing access to paid rest breaks, adequate shade, warming or cooling stations, drinking water, and personal protective equipment (PPE).

Employers must also require supervisors and managers to complete a quarterly training program established by the Department of Health to recognize the signs of overexposure to hot and cold temperatures and ensure that appropriate PPE is available. The bill establishes specific protections for employees working in vehicles, warehouses, and outdoor settings, requiring adequate insulation and heating/cooling equipment in these environments.

Additionally, it mandates quarterly training for employees in these settings to identify risk factors, signs, and symptoms of cold stress and heat-related illnesses, inform them of available protections, outline employer procedures for monitoring temperature conditions, and demonstrate the proper use of PPE. Discrimination against employees for the employer's failure to comply with these requirements is deemed an unlawful employment practice. The Department of Health is tasked with creating and implementing the necessary training programs, and the act is set to take effect on January 1, 2026.
