If you are working in the HVAC industry, you have likely heard of the Ozone Depletion Prevention (ODP) Certification. But after going to school to complete your G3 and G2 license, as well as possibly air conditioning training and numerous other work-related training sessions, I'm sure you're wondering "Do I really need to get my ODP certificate, too?"
If you are working with CFCs, HCFCs, or HFCs, for example, the answer is yes.
