What is a common symptom of chlorine gas exposure?

Chlorine gas exposure can lead to a range of respiratory symptoms because it is a powerful irritant, particularly to the mucous membranes in the respiratory system. Coughing or difficulty breathing is a direct result of inhalation of chlorine gas, which can cause immediate irritation of the throat and lungs. This response can range from mild coughing to severe respiratory distress, depending on the concentration of the chlorine and the duration of exposure.

Other symptoms like dizziness, skin rash, or headache can occur under certain circumstances of exposure or from other agents, but coughing and breathing difficulties are the most characteristic symptoms associated specifically with inhalation of chlorine gas. The primary concern with chlorine exposure is its impact on the respiratory system, making it crucial for pool operators to monitor and manage chlorine levels effectively to prevent such exposure incidents.
