Establishes occupational heat stress standard and "Occupational Heat-Related Illness and Injury Prevention Program" in DOLWD.

New Jersey's S 1447 establishes a state heat stress safety standard and prevention program for workers. It requires employers across all industries (including agriculture, construction, and indoor settings without climate control) to implement written heat safety plans by June 1, 2025. Key provisions include providing potable water under 59°F, mandatory rest breaks in shaded/cool areas, heat exposure monitoring, emergency response protocols, and heat alert systems for forecasted heatwaves. The law mandates employer-developed plans to prevent heat-related illness, requiring worker input and language accessibility for non-English speakers.
