Why is cross-contamination between refrigerants in storage a concern?

Keeping refrigerants separate in storage is essential because different refrigerants must stay pure and uncontaminated. When residues from one refrigerant mix with another, the resulting blend can be unusable for reclaim or reuse, may degrade performance, and can even create impurities that complicate future processing. Reclaim facilities have strict impurity limits, so cross‑contamination can render a batch noncompliant and require disposal instead of reclamation. This combination of safety, performance, and regulatory compliance is why avoiding cross‑contamination is the primary concern. Storage practices like labeling, sealing, and dedicating containers and lines to a single refrigerant help prevent these issues.
