Empty chlorine cylinders should always be stored in an upright position and chained to an appropriate structure. This practice is crucial to ensure stability and safety. Storing cylinders upright helps prevent them from tipping over, which could potentially lead to damage or accidental release of residual gas if the cylinder is not entirely empty. Chaining the cylinders provides an additional layer of security, ensuring that they remain upright and reducing the risk of accidents in the storage area.

Storing cylinders horizontally can create a risk of rolling or falling, which could cause leaks or damage. Keeping them in a closed container could restrict airflow and create a hazardous situation if any residual gas is present. Lastly, leaving cylinders on the ground without restraints poses a significant safety hazard, as they could easily tip over or be subjected to environmental elements that increase the risk of accidents. Therefore, the proper method of storing empty chlorine cylinders is critical for safety and compliance in handling such chemicals.
