What is the appropriate action to slow a chlorine gas leak?

The appropriate action to slow a chlorine gas leak involves rotating the leaking section of the pipe upwards. This method can help manage the situation effectively because chlorine gas is denser than air and will tend to accumulate at lower levels. By positioning the leak in an upward orientation, any escaping gas may have a better chance of dispersing upward and away from the immediate area rather than spreading along the ground where it could pose a greater risk to individuals nearby.

Increasing the ventilation in the area could be beneficial for dispersing the gas but is not a direct method to slow the leak itself. While sealing the leak with tape or covering it with cloth may seem like a quick fix, these options are typically insufficient for managing a gas leak, especially one involving chlorine, which requires more robust methods for control and safety.
