Question

Quizplus · Accepted Answer

Technician A is correct in stating that a refrigerant service cylinder should have a pressure relief valve to prevent over-pressurization and potential danger.

Technician B is incorrect in stating that a fusible plug gives excellent protection between 160°F and 180°F. A fusible plug is designed to melt and release pressure in case of extreme temperatures, but its melting point can vary depending on the specific material and design, and it may not provide reliable protection within the range stated by Technician B. Additionally, fusible plugs are not typically used for pressure relief in refrigerant cylinders.
