In many countries, products containing methylene chloride must carry labels warning of the health risks.

In February 2013, the U.S. Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health warned that at least 14 bathtub dressers had died from exposure to DCM since 2000. The workers had been working alone, in poorly ventilated bathrooms, with inadequate or no respiratory protection, and had not been trained on the dangers of DCM. Since then, OSHA has issued DCM standards. In the European Union, the European Parliament voted in 2009 to ban the use of DCM in paint removers for consumers and many professionals. The ban went into effect in December 2010.


In Europe, the Scientific Committee on Occupational Exposure Limits (SCOEL) recommends occupational exposure limits for DCM (8-hour time-weighted average) of 100 PPM and short-term exposure limits (15-minute) of 200 PPM.


Concerns about their health effects have led to the search for alternatives in many of these applications.


On March 15, 2019, the U.S. Environmental Protection Agency (EPA) issued a final rule banning the manufacture (including import and export), processing, and distribution of dichloromethane in all paint strippers intended for consumer use for 180 days, but not affecting other products containing dichloromethane, including many consumer products not intended for paint strippers.


The compound's low boiling point allows the chemical to function in an engine that extracts mechanical energy from tiny temperature differences. An example of a DCM engine is a drinking bird. The toy works at room temperature. [18] It is also used as a fluid in Christmas bubble lights with a coloured bubble tube above as a heat source and a small amount of rock salt to provide thermal mass and nucleation location for the phase change solvent.


DCM chemical welds certain plastics. For example, it is used to seal the casing of an electricity meter. It is commonly sold as the main ingredient in plastic welding adhesives and is also widely used by model-making enthusiasts to join plastic parts together. It is often referred to as a "di-CLO".


It is used in the garment printing industry to remove heat-sealed garment transfers, and its volatility is used in novelty items: bubble lights and jukebox displays.
