a.Plug the relief valve so it stops leaking
b.Take the cylinder out of service and recover its contents into a sound cylinder
c.Paint over the corrosion and keep using it
d.Increase the fill amount to use it up faster
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.
