Regulations & SafetyCâu 62 / 240
A technician notices the pressure relief valve on a recovery cylinder is corroded and weeping refrigerant. What is the correct action?
a.Increase the fill amount to use it up faster
b.Plug the relief valve so it stops leaking
c.Paint over the corrosion and keep using it
d.Retire it and transfer its contents
Giải thích
A damaged or leaking pressure relief valve makes a cylinder unsafe, so it must be taken out of service and its contents recovered into a sound, approved cylinder. Plugging or bypassing a relief valve is extremely dangerous because it removes overpressure protection, and painting over corrosion or overfilling does not fix the hazard. Compromised cylinders should never be filled or transported.
