Chlorine pulmonary agent's lethality is described as which of the following?

• A. High lethality
• B. Readily available
• C. No antidote
• D. Low lethality

Answer: (D)

Chlorine gas is mainly a pulmonary irritant that damages the lining of the airways. Its lethality is described as low because, while exposure can cause severe lung injury and even death at very high concentrations or with prolonged exposure, most people survive with prompt, supportive medical care. There’s no specific antidote for chlorine gas, so treatment focuses on decontamination, providing oxygen, bronchodilators, and supportive respiratory care as needed. This makes it less lethal overall than many other chemical agents, even though it can be dangerous.
