California Wastewater Treatment Operator Practice Exam

What should you do if you are mildly exposed to chlorine gas?

1. immediately evacuate the contaminated area, remain calm, keep warm. breath lightly, avoid coughing

2. pour water on the affected area

3. wait for ventilation

4. apply a bandage

The correct answer is: immediately evacuate the contaminated area, remain calm, keep warm. breath lightly, avoid coughing

The correct choice emphasizes the immediate response to chlorine gas exposure, which is essential for ensuring safety. Evacuating the contaminated area is a crucial step, as it removes the individual from the source of the exposure, reducing the risk of more severe health effects. Remaining calm is important for making clear-headed decisions in a stressful situation. Keeping warm and breathing lightly can help manage anxiety and minimize respiratory distress. It's critical to avoid coughing, as it can exacerbate irritation in the respiratory tract. While options such as waiting for ventilation or applying a bandage might seem relevant in different contexts, neither effectively addresses the direct threat posed by chlorine gas exposure. Water should not be poured on the affected area, as this could react with chlorine in unpredictable ways, potentially worsening the situation. Thus, the chosen response is the most appropriate and comprehensive course of action.
