At what temperature range do fusible plugs on chlorine cylinders melt?

• A. 100-105°F
• B. 120-130°F
• C. 157-162°F
• D. 180-190°F

Answer: (C)

Fusible plugs are safety devices used on chlorine cylinders to prevent the buildup of pressure that could lead to an explosion. These plugs are designed to melt at specific temperatures, allowing the gas to escape safely and reducing the risk of a rupture. The correct answer, which falls within the temperature range of 157-162°F, is critical because it reflects the typical melting point designed to ensure that safety measures activate at temperatures that are potentially dangerous for the pressurized chlorine gas. This range is strategically selected to provide a balance where the plugs will only melt under extreme conditions, thereby ensuring the integrity of the cylinder under regular operating temperatures. Choosing a melting point that is too low might cause the fusible plug to activate inadvertently, while a melting point that is too high could fail to prevent a disaster in case of a fire or excessively high temperatures. Therefore, the 157-162°F range is a well-calibrated safeguard against danger associated with chlorine storage and handling.
