The Environmental Protection Agency (EPA) has formally announced the withdrawal of rules proposed in 2017 banning methylene chloride’s (MC) commercial paint stripping uses and n-Methylpyrrolidone’s (NMP) paint stripping uses. EPA cites pending risk management processes for the chemicals under TSCA Section 6(a) to justify the withdrawal.
Every single day, workers and communities are exposed to and harmed by these dangerous chemicals. Dozens of families have lost loved ones to the use of methylene chloride paint strippers on the job. EPA’s refusal to act in the wake of thousands of citizen comments, a mountain of scientific evidence, and hours of testimony in support of these protections is public health malpractice.
Even if you don't live in the United States here are a few things you should know about these hazardous chemicals:
Methylene Chloride
Also known as dichloromethane or DCM, is a solvent used in a range of products. Methylene chloride has been linked to cancer, cognitive impairment, and asphyxiation. Many methylene chloride-based paint and coating removers are used in areas with limited ventilation such as bathrooms, allowing fumes to build up. Methylene chloride vapor is heavier than air, so it concentrates low to the ground, right around the level where people stripping surfaces are breathing. According to EPA, respiratory protection may not be enough to protect people from being exposed where levels of methylene chloride are high.
N-Methylpyrrolidone
Also known as NMP or 1-methyl-2-pyrrolidone, is a solvent used in a range of products. The average consumer is most likely to encounter it in paint strippers, even though safer alternatives exist. NMP has been closely linked to developmental impacts including miscarriages. EPA describes NMP as a developmental toxicant.
