Which gas can cause lung and skin irritation depending on its concentration and exposure time?

Chlorine is known to be a toxic gas that can cause irritation to the respiratory system, skin, and mucous membranes. When inhaled, chlorine can lead to symptoms such as coughing, throat irritation, and difficulty breathing. The severity of these symptoms is directly related to the concentration of chlorine in the air and the duration of the exposure.

In addition to respiratory distress, chlorine gas can also react with moisture on the skin and in the eyes, resulting in burning sensations and potential tissue damage. At higher concentrations or with prolonged exposure, the effects can become severe, leading to serious health risks.

This property of chlorine makes it critical for operators and handlers to be mindful of safety protocols when working with or around this chemical, as even short bursts of high-concentration exposure can be harmful. Understanding how chlorine behaves in different concentrations and the importance of monitoring exposure times is vital in preventing health-related issues for individuals working in environments where chlorine is used.

In contrast, the other options listed do not typically produce irritation in the same context or severity. Ammonia can cause irritation but is not as commonly associated with skin irritation at lower concentrations as compared to chlorine. Methane is generally non-toxic in its pure form and does not cause irritation, while carbon dioxide
