The HVACR industry is rapidly transitioning away from Hydrofluorocarbons (HFCs) like R-410A due to their high Global Warming Potential (GWP). The 9th Edition V2 heavily emphasizes the safe handling, storage, and recovery of mildly flammable (A2L) refrigerants like R-32 and R-454B, as well as highly flammable (A3) hydrocarbons like R-290 (propane). Technicians must understand the specific tools, spark-proof recovery machines, and ventilation requirements needed when working with these substances. 2. Phase-Down Schedules and Regulations
The EPA exam requires a lot of rote memorization. Create flashcards for evacuation micron levels, vacuum inches of mercury required for specific recovery equipment, leak percentage thresholds, and refrigerant color codes.

Awarded to technicians who successfully pass all four sections (Core, Type I, Type II, and Type III). Core Topics Covered in the 9th Edition V2 Manual
The manual explains the chemical reactions causing ozone layer degradation. Chlorofluorocarbons (CFCs) and Hydrochlorofluorocarbons (HCFCs) contain chlorine. When released, solar radiation breaks down these molecules, freeing chlorine atoms to destroy ozone ( O3cap O sub 3 ) molecules. The Clean Air Act and Phase-Outs
