Safety and regulation

Tris is mutagenic [2] and listed as an IARC Group 2A carcinogen. [3] It is one of the chemicals covered by the Rotterdam Convention. In the United States, the Consumer Product Safety Commission banned the sale of children's garments containing tris in 1977. [4] This regulatory change came about as a result of the research of Bruce Ames and Arlene Blum. [5]
