Phosgene gas inhalation is known for which effect?

• A. An extremely corrosive gas from burning plastics. Does tremendous tissue damage / total destruction of lung tissue and eyeballs on contact
• B. Mild irritant with no tissue damage
• C. Causes only eye irritation
• D. Produces a mild cough

Answer: (C)

Phosgene inhalation primarily injures the lungs. It damages the alveolar-capillary barrier, leading to fluid leakage into the air spaces and non-cardiogenic pulmonary edema, with oxygenation impairment that can develop hours after exposure. Eye irritation can occur, but the defining and most dangerous effect is lung injury, not just eye symptoms. The exam item describing it as “only eye irritation” misses the major pulmonary toxicity that EMS providers must recognize and manage, including watching for delayed respiratory distress and providing supportive care such as oxygen and airway management as needed.
