The "Extreme Temperature Worker Protection Act" introduced as a new chapter to Title 28 of the General Laws, aims to safeguard workers from the dangers of working in extreme hot or cold conditions. It requires employers to provide a safe workplace by implementing measures such as rest breaks, shade or warmth, drinking water, and training. The bill defines terms like "acclimatization," "heat illness," and "cool-down area," and sets specific temperature thresholds for indoor and outdoor work environments. Employers must develop a written program to prevent heat-related illnesses, provide access to drinking water, encourage hydration, and mandate cool-down breaks, which are to be compensated unless they overlap with unpaid meal breaks.

For cold conditions, the bill stipulates that employers must develop a written program to prevent cold-related illnesses, provide warm liquids and areas, supply wind-protective clothing, and ensure prompt medical attention for affected workers. Employers are required to monitor temperatures, provide appropriate personal protective equipment at no cost, and maintain adequate heating in vehicles. The bill also mandates compensated warm-up rest periods every two hours, removal of employees from work if they get wet, and training on working in extreme temperatures. It includes anti-retaliation provisions and requires employers to keep records of temperature-related illnesses and fatalities. The act will be effective upon passage.
