What happens to chlorine gas if it leaks inside a facility?

When chlorine gas leaks inside a facility, it tends to rise and collect on the ceiling due to its density. Chlorine is denser than air, which means that instead of dispersing evenly or falling to the ground, it will accumulate at higher levels in the room. This behavior can pose significant safety hazards, as workers may not immediately notice the increased concentration of chlorine at ceiling height. Additionally, if the room is poorly ventilated, the risk of exposure to chlorine gas increases as it can create a toxic environment at elevated levels. Understanding this characteristic is crucial for implementing safety measures and responding effectively to gas leaks in wastewater treatment facilities or any environment where chlorine is utilized.
