Recovery & RecyclingQuestion 211 of 240

The main danger of overfilling a recovery cylinder beyond 80 percent is that:

a.The valve will freeze open
b.Heat can make it burst
c.The refrigerant will lose purity
d.The cylinder color will fade

Explanation

An overfilled cylinder has no room for the liquid to expand, so a rise in temperature can make it hydraulically full and burst it, releasing refrigerant with great force. This is why the 80 percent limit and weighing are strict rules. Overfilling is one of the most serious cylinder hazards.
