The Extreme Temperature Worker Protection Act is designed to protect employees from health risks associated with extreme temperatures in the workplace. It requires employers to create and implement a comprehensive protection plan that addresses both heat-related and cold-related injuries. This includes monitoring temperatures, providing access to potable water, and establishing designated break areas. The bill also mandates acclimatization protocols for employees, ensuring they can gradually adapt to temperature extremes, and outlines specific actions to be taken when temperatures exceed certain thresholds, such as mandatory breaks and monitoring for signs of illness.

Additionally, the bill introduces regulations for work vehicles, requiring functioning heating systems for employees who spend significant time in them. Employers must provide at least a 15-minute rest break every two hours when temperatures drop below 40 degrees Fahrenheit, with specific provisions regarding compensable work assignments. The legislation also emphasizes the need for an emergency response plan, employee training on temperature-related injuries, and protections against retaliation for exercising rights under the act. The bill is set to take effect on May 1, 2027.
