What method can quickly locate chlorine leaks?

1. Using a smoke detector

2. Using a vapor from ammonia solution

3. Using water mist

4. Using a chemical detector

The correct answer is: Using a vapor from ammonia solution

The most effective method for quickly locating chlorine leaks is using a vapor from an ammonia solution. When ammonia is exposed to chlorine gas, a visible white cloud forms due to the reaction between the two substances. This clear indicator can help operators quickly pinpoint the location of a chlorine leak, making it essential for ensuring safety in wastewater treatment facilities. In contrast, while smoke detectors are beneficial for fire detection, they are not designed to detect chlorine gas specifically. Water mist may disperse chlorine gas but will not effectively pinpoint the leak, and although chemical detectors can detect chlorine, the rapid visibility provided by the ammonia reaction makes it a more immediate and practical choice in an emergency situation.
