A bill for an act establishing requirements relating to heat response in work areas and providing penalties.

HF 742 requires Iowa employers to provide heat safety measures for workers exposed to extreme heat conditions (heat index ≥90°F). Specifically, it mandates employers to offer shaded areas for outdoor workers, provide at least 32 ounces of cool drinking water hourly, and implement adjusted work-rest schedules (10 minutes every 2 hours for 90-100°F, 15 minutes hourly above 100°F). The law applies to all employers with employees working in heat-exposed environments and includes penalties of up to $500 per violation for noncompliance. Enforcement falls to the Iowa Department of Inspections, Appeals, and Licensing, which will oversee compliance and issue fines.
