At what temperature does the fusible plug melt on a 150 lbs. gas chlorine cylinder?

The melting range of the fusible plug on a 150 lbs. gas chlorine cylinder is significant for safety in handling compressed gases. Fusible plugs are critical safety features designed to prevent excessive pressure buildup in the cylinder by melting and allowing gas to escape in the event of overheating.

The correct range, 157°F to 162°F, is appropriate because it ensures that the plug will activate in a timely manner in response to elevated temperatures that could potentially lead to a hazardous situation. This temperature range effectively balances the need to be protective without being overly sensitive, which could lead to unnecessary release of gas during standard operating conditions.

Understanding the proper melting temperature of fusible plugs is essential for water operators since it directly impacts how gas cylinders are stored, handled, and monitored. Safe handling practices include ensuring that cylinders are kept in a temperature-controlled environment to prevent them from reaching the melting point of the fusible plug. This knowledge is crucial for compliance with safety regulations and for ensuring the safety of personnel handling chlorine gas.
