What is the maximum amount of liquid recommended in a chlorine cylinder or container?

The recommended maximum amount of liquid in a chlorine cylinder or container is set at 85% full to ensure safety during storage and handling. This guideline is crucial because chlorine in its liquid form is pressurized, and as temperature changes, the pressure within the cylinder can fluctuate. Overfilling the cylinder increases the risk of leaks or ruptures due to this pressure change, which could lead to dangerous situations, including toxic gas release. Maintaining the liquid level at or below 85% helps accommodate expansion and reduces the likelihood of accidents. It also facilitates the proper functioning of the cylinder valves and regulators, ensuring safe and accurate dispensing of chlorine for water treatment processes.
