What is the purpose of fusible plugs in chlorine cylinders?

Fusible plugs in chlorine cylinders are designed to prevent cylinders from rupturing when exposed to excessive heat. They are made with materials that can melt at a specific temperature, allowing the gas to escape safely rather than causing an explosion or rupture of the cylinder. This design feature is particularly crucial for maintaining safety standards in scenarios where chlorine cylinders may be subjected to high temperatures, such as during a fire or extreme environmental conditions. By melting and releasing gas in a controlled manner, fusible plugs act as a safety mechanism to protect both the cylinder and the surrounding area from catastrophic failure. This capability is vital in handling and storing hazardous materials like chlorine, ensuring operators can manage these risks effectively.
