EPA 608 609 - EPA Refrigerant Handling Certification EPA Practice Test (608 Core) 1

Question 1

Which federal law established the framework under which EPA Section 608 regulations for refrigerant handling were promulgated?

Accepted Answer

The Clean Air Act, as amended in 1990

Answer

Section 608 regulations were established under Title VI of the Clean Air Act Amendments of 1990, which directed EPA to develop rules protecting stratospheric ozone by restricting refrigerant venting and mandating recovery practices.

Question 2

What does the term 'reclaim' mean in the context of EPA Section 608 regulations?

Accepted Answer

Reprocessing used refrigerant to meet new product purity standards, verified by chemical analysis

Answer

Reclaiming means reprocessing refrigerant to at least the purity level of new product, as determined by chemical analysis — typically performed by a certified reclaimer. This is stricter than 'recover' or 'recycle,' which do not restore the refrigerant to virgin-grade purity.

Question 3

Under Section 608, which of the following is a TRUE statement regarding the venting of refrigerants?

Accepted Answer

Venting of all CFC, HCFC, and HFC refrigerants is prohibited except for de minimis releases

Answer

EPA prohibits the knowing venting of CFCs, HCFCs, and HFCs (and their blends) during servicing, maintenance, repair, or disposal, with narrow exceptions only for de minimis releases that are unavoidable. Charge size and documentation do not create a legal venting exemption.

Question 4

What is the primary environmental concern associated with refrigerants classified as Class I ozone-depleting substances (ODS)?

Accepted Answer

They migrate to the stratosphere and break down ozone molecules through catalytic reactions involving chlorine or bromine

Answer

Class I ODS (such as CFCs and halons) are stable enough to reach the stratosphere, where UV radiation releases chlorine or bromine atoms that catalytically destroy ozone molecules. Each chlorine atom can destroy thousands of ozone molecules before being deactivated.

Question 5

A technician recovers refrigerant from a system and stores it in a recovery cylinder. According to EPA Section 608, which of the following markings is REQUIRED on that cylinder?

Accepted Answer

The cylinder must be labeled to identify the type of refrigerant it contains

Answer

EPA regulations require that recovery cylinders be labeled with the type of refrigerant they contain. This prevents cross-contamination and ensures the refrigerant can be properly handled, recycled, or reclaimed downstream. Cylinders must also meet DOT specifications.
