Quizplus · Accepted Answer

When encountering an unknown refrigerant, it should be treated as contaminated. This is because mixing refrigerants can cause damage to recovery equipment and is not environmentally responsible. Purging unknown refrigerants into the atmosphere is illegal and harmful to the environment. Without knowing the specific type of refrigerant, it cannot be safely assumed to be treated like R-12 or R-134a.
