Low GWP Refrigerant Safety: Flammable and Mildly Flammable Refrigerants

Training Course

As the HVACR industry continues to move forward and innovate, the refrigerants that were once so commonplace are now being phased out. Replacing them are more energy efficient, environmentally friendlier refrigerants, known as Low GWP refrigerants. Many of these new refrigerants are classified by ASHRAE as A2L, or slightly flammable. The industry is also seeing expanded use of some hydrocarbon (A3) refrigerants, such as propane and isobutane. Students and technicians will require additional training for the safe handling and transportation of these refrigerants.

This course provides students and practicing technicians with the information and knowledge necessary to safely handle mildly flammable refrigerants as well as prepare for the ESCO Institute's Low GWP Refrigerant Safety certification exam.

Main topics include:
  • Refrigerant safety
  • Introduction to Low GWP refrigerants
  • Refrigerant properties and characteristics
  • The refrigeration cycle
  • Working with refrigerant blends
  • Proper installation and service guidelines
  • Flammable refrigerant considerations
  • Explanation of associated codes & standards for A2L refrigerants
  • Individuals completing this course will be prepared for ESCO Institute's Low GWP Refrigerant Safety Certification exam. Note: certification exam is separate and not included in the course.
