Dichloromethane

Key Points

Fire

  • Combustible
  • Reacts violently with metals such as aluminium powder, magnesium powder, strong bases and strong oxidants causing fire and explosion hazard.
  • Emits toxic fumes of phosgene, carbon monoxide and hydrogen chloride when heated to decomposition or involved in combustion.
  • In the event of a fire involving dichloromethane, use fine water spray and normal fire kit with breathing apparatus

Health

  • Toxic by ingestion, inhalation or dermal contact
  • CHIP: Possible carcinogen
  • Ingestion may cause gastrointestinal burns, haemorrhage, and necrosis.
  • Inhalation causes dyspnoea, cough and pneumonitis with bilateral exudative pleural effusions
  • Dermal contact causes a burning sensation, numbness, coldness and pain.
  • Ingestion, inhalation and extensive or prolonged dermal contact can cause systemic effects including headache, light-headedness, blurred vision, fatigue, disorientation, confusion, drowsiness, agitation, ataxia, rash, skin flushing and diaphoresis
  • Eye contact with vapour can cause irritation. Contact with liquid methylene chloride may cause corneal burns

Environment
