EPA Bans Deadly Methylene Chloride in Consumer and Most Work Settings

The U.S. Environmental Protection Agency announced Tuesday a comprehensive ban on methylene chloride, a highly toxic chemical linked to dozens of deaths and serious long-term health risks. The agency's action prohibits the chemical in all consumer products and most workplace settings, marking its most extensive regulatory measure since a 2015 investigation by the Center for Public Integrity exposed the dangers of methylene chloride-based paint strippers.

Methylene chloride is a volatile compound that can cause immediate death by asphyxiation when inhaled in high concentrations, as it shuts down the brain's respiratory center. Prolonged exposure, even at lower levels, has been associated with increased risks of multiple cancers. Despite a 2019 ban on its use in consumer paint-stripping products, the chemical remained widely available in other applications, including aerosol degreasers and sealants.

The EPA's decision follows years of advocacy by families of victims and chemical-safety organizations. Lauren Atkins, whose son Joshua died in 2018 while using methylene chloride-based paint stripper, expressed cautious relief at the ruling. "It’s a good rule," she said. "I think it could be better, I think it could have gone farther, but it’s a whole lot better than what we had."

The EPA cited at least 85 deaths and long-term health dangers in determining that methylene chloride posed "unreasonable risks." However, the restrictions will not take effect immediately. Consumer sales will be fully banned within one year, while most commercial and industrial uses must cease within two years. A 10-year extension has been granted for certain emergency uses by NASA.

The chemical's hazards have been documented for decades. A 1976 medical journal article criticized the EPA and the Consumer Product Safety Commission for failing to act despite known dangers. The EPA first listed methylene chloride among 10 high-risk chemicals for evaluation in 2016.

The new rule comes after years of resistance, including during the Trump administration, when top officials sought to roll back protections rather than strengthen them. Manufacturers also lobbied against stricter regulations. Families of victims, including Brian Wynne—whose brother Drew died in 2017—worked tirelessly to push for the ban. "Let’s look at the toxic 10 and start whittling down all of them," Wynne said. "I think we can all agree that anything labeled as part of the toxic 10 shouldn’t be part of our daily lives."

The EPA's phased approach allows businesses time to transition away from methylene chloride while implementing protections for workers who will continue handling the chemical in limited capacities. Advocates hope the victory will inspire further action on chemical safety.

"Persistence is key," Wynne said. "The takeaway should be: If something’s not right, don’t be afraid to raise your voice."

The EPA's ruling reflects growing scrutiny of hazardous chemicals in consumer and workplace environments, though critics argue the phase-out timeline may still allow preventable harm. For families like the Atkins and Wynnes, the ban represents a hard-won but long-overdue step toward protecting public health.
