Route of Exposure

  • Inhalation - Inhalation is the major route of phosgene exposure. Phosgene's effects as a respiratory irritant can be mild and delayed, which may result in a lack of immediate avoidance leading to exposure for prolonged periods. Phosgene is heavier than air and may cause asphyxiation due to oxygen displacement in poorly ventilated, low-lying, or enclosed spaces.
  • Skin/Eye Contact - When phosgene gas contacts moist or wet skin, it may cause irritation and erythema. High airborne concentrations can also cause corneal inflammation and opacification. Direct contact with liquid phosgene under pressure can cause frostbite as well as severe irritation and corrosive effects.
  • Ingestion - Ingestion of phosgene is unlikely because it is a gas at room temperature.
