California Code, Health and Safety Code - HSC § 19821

The Legislature finds and declares that results from recent research and testing by the federal government indicate the chemical tris (2, 3-dibromopropyl) phosphate, hereafter referred to as “Tris,” which is widely used in children's sleepwear as a flame retardant, may be a cancer-causing agent.

The State Fire Marshal shall adopt regulations prohibiting the use of Tris in all clothing. The State Fire Marshal, in conjunction with the Department of Consumer Affairs, shall prepare and disseminate information to consumers on how to identify clothing, including children's clothing subject to the provisions of Section 19820, which has been treated with Tris or any other flame-retardant chemicals used in the manufacture of consumer products which a state or federal agency has determined under state or federal law to be a health hazard of sufficient magnitude to warrant prohibition of their manufacture or sale.
