EPA 608: Core

The Core section is taken by everyone who sits any EPA 608 type. It is 25 questions; you need 18 correct (72%).

Topics that show up every sitting:

• Stratospheric ozone, chlorine, ODP vs GWP, CFCs / HCFCs / HFCs / HFOs
• Montreal Protocol and Clean Air Act Section 608
• Recover, recycle, reclaim (AHRI 700 before a change of ownership)
• Venting prohibition (July 1, 1992 for CFC/HCFC; November 15, 1995 for HFCs) and de minimis releases
• Sales restriction, fines, and losing your card
• Gray/yellow recovery cylinders, 80% fill, DOT labels, never refill disposables
• Nitrogen only for leak-test pressure — never oxygen or compressed air
• POE oil, moisture, evacuation/dehydration, P/T charts and non-condensables

Drill Core until you can recite the dates and the 80% cylinder rule without notes, then add a type.
