What is the purpose of the fusible plug in chlorine containers?

The purpose of the fusible plug in chlorine containers is to act as a safety feature. Specifically, it is designed to melt at a certain temperature, typically in the event of a fire or excessive heat surrounding the container. When the fusible plug melts, it releases the pressure within the container, allowing chlorine gas to escape in a controlled manner instead of causing a catastrophic rupture of the cylinder. This design helps to minimize the risk of explosion and protects both the environment and personnel in the vicinity.

It is crucial that the fusible plug is never removed or tampered with because doing so compromises this safety mechanism. Ensuring that the fusible plug remains intact is essential for the safe handling and storage of chlorine gas, making it a critical component in the design of the container.
