Official conclusions for the halogenated FR, TCEP, identify potential cancer, nervous system and fertility risks. The EPA concludes that TCEP (tris(2-chloroethyl) phosphate) poses an unreasonable risk of injury to human health and the environment, as defined under TCSA (Toxic Substances Control Act), and so will propose risk management regulatory actions. Unreasonable risk to the public (consumers) was identified in three out of twenty-one applications considered: fabrics and textiles, foams, wood products, as well as risks to workers in other applications including polymers for aerospace, paints and coatings. EPA also found unreasonable risk for aquatic invertebrates, fish and for people eating contaminated fish. EPA already proposed SNURs (Significant New Use Rule, that is notification requirements) for TCEP in 2023 (pinfa Newsletter n°153) and TCEP is already classified as SVHC (Substance of Very High Concern) in Europe.
