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, ensure the availability of appropriate PPE, and maintain functional heating and cooling equipment.

The bill outlines specific protections for employees working in vehicles, warehouses, and outdoor settings, requiring adequate insulation and heating/cooling equipment in these environments for those who spend more than 60 minutes in such locations. Additionally, it mandates quarterly training for employees in these settings to identify risks associated with extreme temperatures and to understand the protections available to them.

Discrimination or discharge of 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 may establish additional rules and regulations to enforce this section. The act is set to take effect on January 1, 2027.
