EPA-608 REFRIGERANT MANAGEMENT UPDATED EXAM 2025
|70 QUESTIONS WITH VERIFIED ACCURATE SOLUTIONS
1. If a company has a stock of reusable refrigerant containers
that were last hydrostatically tested 4 years ago, what
action should they take to comply with safety regulations?
Continue using the containers without any
further action. Dispose of the containers
immediately.
Schedule hydrostatic testing for the containers before
the 5-year mark.
Paint the containers to indicate they are safe for use.
2. On what characteristics is ASHRAE refrigerant safety
group classification system
Explosives and toxicity
Explosives and flammability
Flammability and toxicity
Acidity and explosiveness
3. To clean refrigerant by the use of filter dryers is
, called ____. recovery
renew
reclaim
recycle
4. A technician is preparing to conduct a leak test on a
refrigeration system. The low side test pressure data plate
indicates a value of 30 psi. If the technician accidentally
applies a pressure of 50 psi during the test, what potential
issues could arise?
The refrigerant will evaporate too quickly, causing
inefficiency.
, The system may experience damage due to excessive
pressure, leading to leaks.
The leak test will be more accurate at higher pressures.
The compressor will operate more efficiently at higher
pressures.
5. What is the purpose of the low side test pressure data
plate value in refrigeration systems?
To determine the maximum temperature of the refrigerant
To establish a safe pressure for leak testing
To calculate the energy efficiency of
the system To identify the type of
refrigerant used
6. Which regulatory body sets the standards for the
shipping of used refrigerant cylinders?
Environmental Protection Agency
Department of Transportation
Occupational Safety and Health
Administration National Institute of
Standards and Technology
7. Which of the refrigerants listed below contain
no chlorine? CFCs
, HCFCs
HFCs
ODCs
8. The purpose of the compressor is to change__.
low-pressure, low temperature liquid to a high-
pressure, high- temperature liquid
