A technician suspects a disposable (single-use) refrigerant cylinder is nearly empty. What is the correct handling under Section 608 practice?
a.Refill it with recovered refrigerant to reuse it
b.Vent the remaining vapor and toss it in the trash
c.Recover the remaining refrigerant (the 'heel') before the cylinder is discarded
d.Puncture it to make sure it is empty before recycling
Giải thích
The small amount of refrigerant left in a 'empty' disposable cylinder, called the heel, must be recovered before the cylinder is discarded, because venting it is illegal. Disposable DOT-39 cylinders must never be refilled, and puncturing a cylinder that still holds refrigerant would vent it. Only after the heel is recovered can the cylinder be safely rendered empty and recycled per local rules.
