Summary: An overhaul in 2016 of the main U.S. chemical safety law, the Toxic Substances Control Act, required EPA to choose the first 10 chemicals for risk evaluation. DCM, one of the first 10 chemicals, is commonly used in paint and coating removal products but is also found in automotive products, adhesives, degreasers, and more. DCM is acutely lethal, and EPA has classified it as a likely carcinogen.
In January 2017, EPA proposed a rule to ban most uses of DCM in paint and coating removal products. For over a year, the current administration made no effort to finalize this action - until families whose sons died from using paint strippers containing DCM met with former EPA Administrator Scott Pruitt in May 2018. Immediately following, Pruitt announced his intention to finalize the ban, but we still have seen no action.
