Which feature is characteristic of chlorine gas inhalation?

• A. Seizures
• B. Severe cough
• C. Watery, irritated eyes
• D. Instant onset of burning in lungs and mouth

Answer: (D)

Chlorine gas acts as a strong irritant to the airways. When inhaled, it reacts with moisture in the respiratory tract to form acids that burn and inflame the mucous membranes almost instantly. That immediate chemical burn produces a burning sensation in the mouth and chest and often triggers a reflex cough and shortness of breath. Among the options, the most characteristic sign is this instant burning in the lungs and mouth because it directly reflects the rapid irritation from chlorine exposure. Other signs like watery eyes or a severe cough can occur with chlorine, but they aren’t as specific or immediate as the burning sensation. Seizures aren’t a typical feature of chlorine inhalation. If exposure is suspected, move to fresh air and seek medical evaluation for potential airway edema or bronchospasm.
