What is used to locate a chlorine gas leak?

The appropriate tool for locating a chlorine gas leak is a chlorine detector. Chlorine detectors are specifically designed to sense and identify the presence of chlorine gas in the air. They often have alarm systems that activate when the concentration of chlorine exceeds a certain threshold, providing immediate alerts to personnel about a potential leak. This is crucial for ensuring safety in facilities that use or store chlorine.

Using ammonia solution to detect chlorine is not effective, as it can react with chlorine to form harmful chloramine gases, which can pose additional health hazards. Water tests and indicators like carbon dioxide sensors are unrelated to chlorine detection and would not be reliable methods for identifying chlorine gas leaks.
