Additional information

Dichloromethane is a highly volatile liquid for which vapour inhalation is the most likely exposure route in occulational settings. It is characterized by moderate acute toxicity by oral route (Acute oral toxicity, Category 4) and low acute toxicity via inhalation and dermal exposures. The effects of acute toxicity of dichloromethane include CNS depression, formation of carboxyhaemoglobin (CO-Hb), as well as effects on liver, kidney and haematological parameters.
