Fusible metal plugs are designed to safely release pressure in chlorine containers during emergencies, particularly if the pressure becomes too high due to temperature increases. The melting point of these plugs is critical for ensuring that they function effectively when needed. The correct range of 158-165 degrees Fahrenheit is the specified melting point for these plugs, allowing them to activate and relieve pressure before the container becomes dangerously over-pressurized.

Understanding this temperature range is essential for safety and compliance with protocols in handling chlorine. It ensures that those working with these materials can take appropriate actions if the ambient temperature approaches this critical melting point, thus preventing possible catastrophic failures. The other temperature ranges do not align with the specified melting point for fusible metal plugs used in chlorine containers, highlighting that safety measures are based on specific and accurate temperature thresholds.
