CFC EPA Regulations & Safety Compliance 5

Question 1

What does the term 'de minimis release' mean in the context of EPA Section 608 regulations?

Accepted Answer

Releases from purging hoses and connections that are unavoidable during good-faith recovery

Answer

De minimis releases are small, unavoidable refrigerant releases that occur when purging hoses or making connections during good-faith recovery efforts, and these are not considered violations.

Question 2

When must a technician use a self-contained (active) recovery machine rather than a system-dependent device under Section 608?

Accepted Answer

When the appliance compressor is not operational

Answer

System-dependent (passive) recovery relies on the system's compressor; when the compressor is non-functional, a self-contained (active) recovery machine must be used.

Question 3

Under the Montreal Protocol's phase-out schedule, what year did the complete production ban on Class I CFCs (like R-11 and R-12) take effect in the United States?

Accepted Answer

1996

Answer

The United States banned the production and import of Class I ozone-depleting substances, including CFCs like R-11 and R-12, effective January 1, 1996.

Question 4

Which of the following is a requirement for refrigerant reclaimers under EPA Section 608?

Accepted Answer

They must be certified and registered with the EPA

Answer

Refrigerant reclaimers must be certified by the EPA and registered with the agency to legally reclaim and resell recovered refrigerant.

Question 5

A technician is servicing a low-pressure centrifugal chiller using R-11. What is the primary safety concern unique to this type of system?

Accepted Answer

System operates below atmospheric pressure, risking air and moisture infiltration

Answer

Low-pressure systems like R-11 chillers operate below atmospheric pressure (in a vacuum), so any leak draws air and moisture into the system rather than pushing refrigerant out.
