EPA 608 Core Study Guide

The Core section covers general refrigerant knowledge that applies across appliance types. It is the foundation for Type I, Type II, Type III, and Universal certification practice.

Key Topics

• Ozone depletion, global warming potential, and refrigerant environmental impact.
• Recovery, recycling, reclaiming, evacuation, and safe cylinder handling.
• Technician certification responsibilities and prohibited refrigerant handling practices.
• Safety data sheets, toxicity, oxygen displacement, and protective equipment.
• Leak repair concepts, substitute refrigerants, shipping, and disposal.

Practice Strategy

Repeat Core study mode until the vocabulary feels automatic. Many missed questions come from confusing recovery, recycling, and reclaiming, so review those terms carefully.

Terms to Know

• Recovery means removing refrigerant from an appliance and storing it in an external container.
• Recycling means cleaning refrigerant for reuse, often by oil separation and filtration.
• Reclaiming means processing refrigerant to meet a purity standard before resale or broader reuse.
• Venting restrictions are central to Section 608 and should be reviewed carefully.

Study Checklist

• Know why refrigerant release is regulated.
• Understand cylinder safety, shipping labels, and recovery equipment basics.
• Review technician responsibilities before service, recovery, and disposal.
• Practice questions that ask for the best action, not only definition questions.
