relative to protecting workers from extreme temperature-related injuries and fatalities in the workplace.

HB 1451 requires all employers in New Hampshire to create written safety plans protecting workers from extreme heat (80°F+ or 15°F-) and cold, including mandatory rest breaks in temperature-controlled areas and access to fluids. It mandates annual employee training on recognizing heat/cold illness symptoms, reporting procedures, and emergency response, while prohibiting retaliation for reporting safety concerns. The law applies to all workplaces with temperature-related risks, particularly outdoor and manual labor jobs like construction and transportation. Employers must develop plans using a step-by-step approach (e.g., hazard elimination, engineering controls) and involve employees in the process.
