RSES Hydrocarbon Refrigerants

Training Course

Hydrocarbon refrigerants were approved for use by the US EPA through their SNAP program in early 2012, for specific refrigeration applications. The course covers practices for the following refrigerant families:

  • HC R-290 (propane)
  • HC R-600a (isobutene)
  • HC R-441A (a blend*)
  • HC R-170 (ethane)
  • HFC R-32 (difluoromethane)


Now in its third edition, the Hydrocarbon Refrigerants safety course covers everything you need to know to work safely with flammable refrigerants, including EPA Regulations; UL Standards; Refrigerant Safety; Service Procedures; and much more.

The full eLearning course a narrated online presentation highlighting key topics from the study guide and a certificate test that assesses your understanding of the materials. A certificate of completion for 8 CEHs/0.8 CEUs is available after the successful completion of the quiz.

** RSES recommends you study ALL the material in the study guide in addition as well as the narrated online presentation in order to fully prepare for the assessment test! **

RSES highly recommends only experienced refrigeration professionals handle HCs. You should already have a solid understanding of the refrigeration cycle and proper handling of CFC, HCFC and HFC refrigerants.
