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.
The Low GWP refrigerant program manual covers:
Registered Proctors can review a digital version of the manual by logging in and visiting the resource center.
PowerPoint presentation: The instructor resource materials include 2 PowerPoint presentations (one for each Section), 208 slides in all, that correlate directly with the training manual. Each slide within the presentation contains speaker notes that are designed to aid the instructor through the presentation and provide additional talking points.
The Low GWP Refrigerant Safety - A2L Refrigerants examination validates that a person possesses the knowledge to safely work with low GWP refrigerants and helps reduce liability. The 50-question, closed-book exam covers the following competencies:
