Requires the Industrial Commission of Arizona to adopt heat illness prevention standards for agriculture, construction, landscaping, oil and gas extraction, airport workers, mail/package delivery workers, and transportation/delivery workers.

Mandates employers provide free potable water (one cup per 15-20 minutes baseline), access to shade or climate-controlled environments when temperatures exceed 90°F, and cool-down rest periods of 15-45 minutes per hour depending on temperature and activity level.

Requires employers to implement high-heat procedures including supervisor monitoring (at least one per 20 employees or buddy system), employee communication with supervisors, designated emergency responders, and gradual acclimatization to heat over 7-14 days for new or returning employees.

Requires comprehensive employee and supervisor training in languages they understand covering heat illness risks, symptoms, first aid, hydration importance, acclimatization, and employer responsibilities, with training provided before work begins.

Establishes private right of action for employees to seek injunctions or recover actual monetary losses or $500 per violation (whichever is greater) for employer violations, and prohibits employer retaliation against employees exercising rights under this section.
