AZ HB2628

Requires the Industrial Commission of Arizona to adopt rules establishing heat illness prevention standards for employers in agriculture, construction, landscaping, oil and gas extraction, and transportation/delivery of heavy materials.

Mandates employers provide employees free access to potable water (one cup per 15-20 minutes baseline), located within 400 feet of work areas, and electrolytes if sweating exceeds two hours.

Requires employers provide shade or climate-controlled environments when temperatures exceed 100°F with capacity to accommodate all employees on rest periods, and allow preventative cool-down rest periods of at least five minutes.

Establishes high-heat procedures when temperatures reach 90°F or higher, including employee supervision or buddy systems, emergency communication capabilities, designated emergency responders, hydration reminders, and pre-shift safety meetings for agricultural workers.

Mandates rest periods of 15-45 minutes per hour depending on temperature and workload, with employers owing one additional hour of pay per workday if rest periods are not provided; requires employee training on heat illness risks, employer procedures, and emergency response; prohibits employer retaliation and allows employees to sue for violations seeking injunctive relief or $500 per violation in damages.
