What do I do with contaminated refrigerant?
Last Updated: 09/28/2007
Contaminated refrigerant requires special handling and special record keeping.  Make sure you follow these guidelines to the letter –if you don't you could be exposing yourself to potential EPA headaches.
  1. Identify the refrigerant in an A/C system with a refrigerant identifier. Use an identifier with a 98%+ accuracy rating, and an identifier that will give you the percentages of R12,  R134a, R22, hydrocarbons, and air.
  2. Recover the contaminated refrigerant.
  3. Dedicate an R-12 recover-only machine, or buy a special machine for this purpose. Robinair Scavenger - Model 17680A
  4. Store the refrigerant in an 'approved' cylinder, a standard DOT-certified grey w/yellow top tank
  5. Dispose of the contaminated refrigerant.

EPA maintains a complete list of reclaimers through the Hotline at 800/296-1996.  Keep in mind, most reclaimers require payment from you to handle your junk refrigerant.
