HB 2684 requires Arizona employers to implement heat and cold safety programs for workers. For heat (80°F+), it mandates written plans covering hydration (1 quart of water per hour), 10-minute cool-down breaks every 2 hours (more frequently during extreme heat), thermometer monitoring, shade access, and acclimatization for new workers. For cold (60°F-), it requires similar written programs with warm areas, cold-prevention training, and reduced exposure schedules. The bill directly affects all Arizona employers with indoor or outdoor workplaces, including construction, agriculture, and vehicle-based jobs (requiring vehicle AC below 80°F).
