Description

Methylene chloride (dichloromethane (DCM)) is a volatile, colorless liquid with a sweet odor, has seen use as a solvent for many applications, including coating of photographic films, in aerosol formulations, and in paint processes where high volatility is desirable, and as a common “blowing” agent for synthetic foams. This volatility may result in high concentrations in poorly ventilated areas. 
DCM is the most water soluble and among the least toxic of the chlorinated methanes, with a predominant toxic effect of CNS depression, expressed as narcosis. Reported systemic effects following nonlethal exposures to methylene chloride include headache, giddiness, stupor, irritability, numbness, psychomotor disturbance, and increased blood carboxyhemoglobin. Prompt removal from exposure typically results in complete recovery. Methylene chloride is mildly irritating to the skin, and dermal absorption is not considered a significant threat to human health. Eye contact may be painful but is not likely to cause serious injury. Adaptation to methylene chloride vapors occurs with repeated contact, decreasing the ability to detect exposure.

 Methylene chloride, a chlorinated solvent, is a volatile, colorless liquid with a sweet-smelling odor. It is often referred to as dichloromethane. Methylene chloride has many industrial uses, such as paint stripping, metal cleaning and degreasing.

Health Hazard

When methylene chloride enters the human body, it affects brain function, such as not being able to concentrate. At high enough levels, it can stop breathing. At lower levels, methylene chloride exposure causes dizziness, fatigue, headaches, and nausea. Methylene chloride breaks down into other chemicals in the body, such as carbon monoxide. In addition, methylene chloride can displace the oxygen in a worker’s environment because of its high vapor pressure. Skin contact with methylene chloride causes burning and redness of the skin.

Applications

Methylene chloride is predominantly used as a solvent in paint strippers and removers; as a process solvent in the manufacture of drugs, pharmaceuticals, and film coatings; as a metal cleaning and finishing solvent in electronics manufacturing; and as an agent in urethane foam blowing.
Methylene chloride is also used as a propellant in aerosols for products such as paints, automotive products, and insect sprays.It is used as an extraction solvent for spice oleoresins, hops, and for the removal of caffeine from coffee. However, due to concern over residual solvent, most decaffeinators no longer use methylene chloride.Methylene chloride is also approved for use as a postharvest fumigant for grains and strawberries and as a degreening agent for citrus fruit.
