Tennessee Wastewater Operator Practice Exam

What should you do with a leaking 1-ton chlorine cylinder if properly trained?

1. Seal the leak

2. Roll the tank until the leak is pointed up

3. Evacuate the area immediately

4. Neutralize the chlorine

The correct answer is: Roll the tank until the leak is pointed up

When dealing with a leaking chlorine cylinder, the appropriate response is to roll the tank until the leak is pointing upward. This action minimizes the risk of chlorine escaping from the cylinder and ensures that any remaining gas can vent safely to the atmosphere, reducing the likelihood of exposure to harmful gas. Chlorine gas is heavier than air and can pose serious health risks and environmental hazards. By positioning the leak upwards, you are allowing any liquid chlorine to remain in the container as much as possible while facilitating the safe escape of any gas that may be present. Understanding the physical properties of chlorine and the mechanics of gas diffusion in emergency situations is critical for ensuring the safety of both the operator and surrounding personnel. This approach is part of a broader emergency response protocol that operators must be trained in, which includes recognizing safe practices for mitigating gas leaks. The other actions listed, such as sealing the leak or neutralizing chlorine, may not be appropriate responses without proper equipment and extensive training. Evacuating the area is crucial in a more extreme situation, but the immediate action of adjusting the cylinder's position can help mitigate the leak while maintaining the safety of the area.
