TWA: 100ppm, STEL: 300ppm


Dichloromethane, CH2Cl2 (DCM), also known as methylene chloride is a colourless liquid with penetrating ether-like or mild sweet odour. DCM vapours are heavier than air. DCM is normally stable, non-flammable and non-explosive when mixed with air;


Exposure of humans to DCM occurs primarily through air. The following health risks are associated with exposure to dichloromethane:

Inhalation - can cause coughing, wheezing and/or shortness of breath. Higher levels of dichloromethane inhalation can lead to headache, mental confusion, nausea, vomiting, dizziness and fatigue.

Skin Exposure - Redness and irritation may occur if skin comes in contact with liquid dichloromethane and, if it remains on the skin for an extended period of time, it may lead to skin burns.

Eye Exposure - Contact with eyes can cause severe irritation and possibly chemical burns to the eyes.

Where is it found

The majority of dichloromethane in the environment is the result of industrial emissions. Some of the many ways dichloromethane is used are:

  • > As an active ingredient in organic-based paint strippers
  • > In the manufacturing of pharmaceuticals and other medicines
  • > Aerosols for insecticides and spray paint
  • > The manufacturing techniques for creating decaffeinated coffee beans and tea leaves
  • > To prepare flavorings in the food and beverage industries
