What is Methylene chloride or Dichloromethane sds(DCM)?
Methylene chloride, which is also called Dichloromethane sds, is a volatile chemical that is produced and imported into the United States, with use estimated at over 260 million pounds per year.
The most possible mechanism for dichloromethane sds toxicity is its ability to increase potassium ions current in certain types of potassium channels. In humans, DCM irritates the skin and eyes, especially when evaporation is prevented; prolonged contact may cause chemical burns. Fatalities due to accidental inhalation and skin contamination have been reported. The main toxic effects of DCM are reversible central nervous system depression (neurophysiological and neurobehavioral disturbances) and carboxyhemoglobin formation extending up to hepatic, renal, cardiovascular, and hematological parameters. DCM-induced spontaneous abortion has been reported in the literature. Death can result from ingestion.
Dichloromethane sds is principally used as a solvent in paint removers and as an aerosol propellant. It is used as a blowing and cleaning agent in the production of urethane foam and plastic fabrication and in paint stripping operations. It is used in metal cleaning, as a solvent in the production of polycarbonate resins, in film processing, and in ink formulations. Dichloromethane sds is used in the food industry as an extraction solvent for spices, caffeine (decaffeinated coffee), and hops. Dichloromethane's use in aerosol products includes paints and automotive spray products.
Dichloromethane sds is an organic solvent that is clear and colourless and has a mild sweet odour. It is a volatile liquid.
Dichloromethane sds can affect you if breathed in and by passing through the skin. Exposure to high concentrations may cause unconsciousness and death. Exposure may irritate the lungs, which can cause a build up of fluid (pulmonary oedema). Lower doses may cause headaches, fatigue, and behaviour similar to being drunk. Dichloromethane sds exposure may cause the heart to beat irregularly or stop. Long term exposures at high levels may damage the liver and brain. The International Agency for Research on Cancer classifies dichloromethane sds as a 'possible human carcinogen'. Worksafe Australia categorises dichloromethane into Category 3, a 'suspected human carcinogen'. It is possible that there is no safe level of exposure to a carcinogen.
Dichloromethane sds will enter the body if we breathe in contaminated air. It can also pass through the skin.
Workers in the industries that use or produce dichloromethane sds are at risk of exposure. Consumers can be exposed to dichloromethane sds by exposure to air from production and processing facilities using dichloromethane sds. Consumers may also be exposed to dichloromethane sds when using consumer products containing dichloromethane sds, especially if there is not good ventilation. Note above the large number of consumer products containing dichloromethane sds.
