An Act to establish extreme temperature worker protections

SD 1531 requires employers to protect workers from extreme heat and cold hazards by implementing safety plans. It directly affects all workers in covered settings - including farmworkers, day laborers, temporary staff, and those in outdoor or unregulated indoor environments - when temperatures reach 80°F or higher (heat) or 60°F or lower (cold). Key provisions mandate paid rest breaks, access to shade/warmth, adequate drinking water, supervisor and worker training, and risk evaluations based on factors like humidity and workload. The law also specifies acclimatization protocols for new workers and defines "cool-down areas" to ensure safe temperature recovery.
