What should be done with a fusible plug once chlorine is withdrawn from a container?

The correct response emphasizes the importance of maintaining the integrity of the fusible plug as a safety mechanism. A fusible plug is designed to prevent pressure buildup in containers that store hazardous materials, such as chlorine, by melting at a certain temperature and allowing gas to escape safely. When chlorine is withdrawn from the container, the fusible plug serves a critical role in ensuring that the container remains safe for future use.

By stating that the fusible plug should never be removed or tampered with, it underscores the necessity of proper safety protocols in handling pressurized containers. Removing or tampering with the plug can lead to the risks associated with pressure buildup, which can potentially result in dangerous situations, including leaks or explosions.

Understanding the role of the fusible plug is essential for safe operations within facilities that handle chlorine and other hazardous materials. Proper adherence to safety practices helps prevent accidents and ensures that equipment remains compliant with regulatory standards.
