The US Environmental Protection Agency proposes to ban most consumer, industrial, and commercial uses of dichloromethane under TSCA regulations

 

The United States Environmental Protection Agency (EPA) recently announced that, according to the Toxic Substances Control Act (TSCA), it is proposed to ban most uses of dichloromethane. This dangerous chemical will cause serious health risks to human beings.

 

The proposal will protect people from these risks while allowing certain uses to continue, limiting usage to strict workplace controls and minimizing worker exposure.

 

1. Usage
The use of dichloromethane is still widespread, including aerosol degreasers, paints, coatings, brush cleaners, adhesives and sealants, as well as in the manufacturing of other chemicals in industrial environments. For example, dichloromethane is used as a chemical intermediate for the production of hydrofluorocarbons (HFCs) 32 in refrigerant mixtures.

 

2. Harmful to health
The unreasonable risk determination of dichloromethane by the EPA is driven by multiple factors such as workers, occupational non users, and consumers. The EPA has identified the risks of adverse effects on human health, including liver diseases caused by inhalation and skin exposure to dichloromethane, as well as triggers for cancer.

 

3. Subsequent measures
The risk management rules proposed by the US Environmental Protection Agency will gradually reduce the manufacturing, processing, and distribution of dichloromethane for all consumer and most industrial and commercial purposes, with most of them fully implemented within 15 months.
For most of the uses of dichloromethane that the EPA proposes to prohibit, the EPA has found that related alternative products can also achieve costs and benefits similar to dichloromethane products.

 

The EPA will receive public opinion on the proposed rules for dichloromethane within 60 days after its publication in the Federal Register.
