Requires the Commissioner of Labor and Workforce Development to establish a heat stress standard by June 1, 2025, setting heat exposure levels that trigger employer protective actions for both indoor and outdoor workers.

Mandates employers develop and implement written heat-related illness and injury prevention plans within 30 days of the act's effective date, including procedures for monitoring heat exposure, providing potable water below 59°F, paid rest breaks, access to shade or cool-down areas, and emergency response protocols.

Requires annual employee training on heat-related illness risk factors, symptoms, prevention measures, and emergency procedures, with additional training requirements for supervisors on recognizing high-risk situations.

Establishes anti-retaliation protections for employees who report heat-related concerns, refuse unsafe work, or participate in proceedings under the act, with a 90-day rebuttable presumption of retaliation for adverse actions.

Creates administrative penalties of $500 to $5,000 per affected employee for violations, authorizes stop-work orders for non-compliant employers with $5,000 per day penalties for violations, and exempts amusement parks from the requirements.
