On April 30, 2024, the U.S. Environmental Protection Agency (EPA) announced a ban on multi-purpose methylene chloride under the Toxic Substances Control Act (TSCA). This measure aims to ensure its safe use through strict worker protection programs. The ban takes effect 60 days after its publication in the Federal Register.
Methylene chloride, linked to various severe health issues including multiple cancers and neurotoxicity, is now subject to new regulations. These mandate a phased reduction in its use across consumer, industrial, and commercial applications, including home remodeling. Consumer uses will be phased out within one year, while industrial and commercial uses have a two-year cessation timeline.
In certain essential industrial applications, the regulation allows continued use of dichloromethane, supported by the Workplace Chemical Protection Program. This initiative sets strict exposure limits, requires detailed monitoring, and mandates training and information for workers to mitigate health risks from chemical exposure. Businesses must comply with these updated protocols within 18 months of the risk management guidelines' issuance and conduct regular assessments. Key applications include:
- Use in the production of other chemicals, including chemicals that are important in efforts to reduce global warming outlined in the American Innovation and Manufacturing Act.
- Production of battery separators for electric vehicles.
- Use as a processing aid in a closed system.
- Use as a laboratory chemical.
- Use in plastic and rubber manufacturing, including polycarbonate production.
- Use in solvent welding.
Exporting companies must closely monitor U.S. regulations and adapt strategies to mitigate compliance risks. ChemRadar will continue to provide updates, aiding businesses in maintaining compliance.
