Exposure to Methylene Chloride (MC)

Over 9,000 construction companies use products that contain the hazardous chemical, methylene chloride.

Some construction companies use consumer products that contain the hazardous chemical methylene chloride.

Exposure often happens when workers are stripping paint or other coatings, applying foam, painting with epoxy paint, cleaning equipment with solvents, and spraying adhesives.

Workers are more likely to be exposed to high levels of MC when working in small, enclosed spaces that are not well ventilated.

Exposure may occur through inhalation, by absorption through the skin, or through contact with the skin. OSHA considers methylene chloride to be a potential occupational carcinogen.
