What is a common sensory effect of chlorine exposure?

The common sensory effect of chlorine exposure is burning of the eyes, nose, and mouth. Chlorine is a strong irritant and can cause significant discomfort upon contact with mucous membranes, which includes the eyes and the lining of the respiratory tract. When chlorine gas is inhaled or comes into contact with these sensitive areas, it triggers a strong burning sensation that can also lead to tearing, coughing, and a feeling of irritation in the throat and lungs.

This immediate physical reaction is a protective response of the body to avoid further exposure to the harmful gas, signaling that the chemical is present and can cause more serious health effects if not addressed. The other options, while they can occur due to various factors or exposures, are not the primary sensory effects directly associated with chlorine exposure. Nausea and headaches, confusion and dizziness, as well as sneezing and coughing can result from a variety of irritants or conditions, but burning sensations in the mucous membranes specifically point to chlorine or similar irritative substances.
