What is the purpose of a fusible plug in a chlorine tank?

The purpose of a fusible plug in a chlorine tank is to prevent cylinder explosions at high temperatures. Fusible plugs are designed to melt at predetermined elevated temperatures, allowing gas to escape safely if the tank experiences overheating. This mechanism acts as a safety feature, reducing the risk of a catastrophic failure by releasing the pressure within the container in a controlled manner.

As the temperature rises, there is a corresponding increase in pressure within the tank. If this pressure becomes excessively high due to overheating, the fusible plug will melt, creating an outlet for the gas. This prevents the potential for an explosion, which can occur if the tank remains sealed under extreme conditions.

Understanding the role of fusible plugs is crucial for water operators, especially when handling chlorine or other hazardous materials. Ensuring safety in the handling and storage of these substances protects both the operators and the surrounding environment.
