Why must R-500 be recovered into its own clearly marked vessel?

When dealing refrigerant blends, keeping each one in its own clearly marked vessel is essential. R-500 is a specific blend whose value and properties rely on a fixed composition. If it’s recovered in the same vessel as other refrigerants, their vapors mix and the composition changes. That contamination makes the recovered material unreliable for reclamation or proper disposal and can obscure what the material actually is. So the primary reason for dedicated, clearly labeled containers is to prevent mixing and preserve the integrity of R-500. Labeling and avoiding cross-contamination matter, but the key idea is preserving the blend’s identity and ensuring safe, compliant recovery.
