Tris(2,3-dibromopropyl) phosphate ("tris") is a chemical once widely used as a flame retardant in plastics and textiles.

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] Arlene Blum was one of those involved in getting tris banned.
