Question: 1 / 400

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

It will disperse evenly throughout the room

It will rise and collect on the ceiling

Chlorine gas is heavier than air, which means that when it leaks inside a facility, it tends to rise initially due to the pressurized release but will eventually settle in lower areas. However, as it accumulates, it often collects at or near the ceiling. This behavior is significant because it poses a hazard since workers in the facility may not realize that chlorine has accumulated above them, leading to potential exposure.

Understanding the properties of chlorinated compounds is essential in wastewater treatment and safety protocols. Since chlorine gas is denser, ventilation systems must be designed to manage and disperse potential leaks effectively, ideally preventing a concentration buildup that could lead to health risks. Proper monitoring and safety mechanisms should be in place to detect and address chlorine leaks promptly.
