Why is it important to monitor temperatures at chlorine cylinders?

Monitoring temperatures at chlorine cylinders is crucial primarily to avoid the melting of fusible plugs. Fusible plugs are safety features designed to release chlorine gas safely in the event of a fire or excessive heat. These plugs are made from materials that melt at specific temperatures, allowing the pressurized gas to escape and prevent cylinder rupture, which could lead to catastrophic failures.

Maintaining temperature control helps ensure that these plugs function as intended, providing a critical safety measure in facilities that handle chlorine. The risk of excessive heat leading to plug failure emphasizes the need for vigilant temperature monitoring to ensure the integrity and safety of the chlorine storage system.

Other factors like preventing corrosion, maintaining chlorine effectiveness, and ensuring safe handling do relate to broader safety and operational practices but are less directly tied to the specific function of the fusible plugs in regulating temperature.
