What is the most likely symptom one could expect upon exposure to a very small percentage of chlorine in the air? A ______ sensation in the eyes and throat.

• A. Itching
• B. Burning
• C. Stinging
• D. Numbing

Answer: (B)

Chlorine gas irritates mucous membranes, so even at low concentrations it commonly produces a burning sensation in the eyes and throat as the irritated tissues respond to the chemical. Itching is more typical of allergic reactions, and numbness isn’t expected with mild chlorine exposure; stinging can occur but burning is the standard way this irritant presents. This immediate burning helps signal irritation before more severe symptoms develop.
