Common miss
Direct answer
The common mistake is treating Why is overfilling a recovery cylinder dangerous as a loose phrase instead of a rule, condition, or field decision with consequences. A recovery cylinder needs safe fill control because liquid refrigerant can expand and raise pressure as temperature changes. If you miss this area, review the explanation, tag the weak concept, and drill nearby topics such as Core safety and refrigerant handling, Type I small appliances, Type II high-pressure systems.
How to use this answer
Read the answer once, then prove it by choosing an answer in a practice question before looking at the explanation. If the miss repeats, tag the domain as Core and drill a smaller set before returning to mixed practice.
