EPA Practice 1

This EPA practice quiz is specifically designed to prepare you for the Environmental Protection Agency (EPA) certification exam, a critical step for any HVAC technician working with refrigerants. This quiz simulates the format of the actual EPA exam, covering all the necessary topics such as refrigerant types, handling, recovery techniques, and environmental impact. The questions range from basic concepts to more complex scenarios, providing a comprehensive review of the material. Whether you’re aiming for Type I, II, III, or Universal Certification, this practice quiz will help you assess your current understanding, pinpoint areas for further study, and build the confidence needed to pass your EPA exam. Perfect for both beginners and experienced technicians, this tool is your key to mastering the essentials of responsible refrigerant handling and compliance with environmental regulations.

1 / 10

If a reclamation facility receives a tank of mixed refrigerant, they may:

vent the refrigerant.

resell the refrigerant for reuse in its current state.

refuse to accept the refrigerant or charge extra for processing it.

agree to separate the refrigerants, by the fracking process.

2 / 10

Which of the following statements about “self-contained” recovery devices is true?

They remove refrigerant from an appliance without the assistance of components in the appliance

They can only be used on air conditioning and refrigeration equipment containing less than 15 pounds of refrigerant

They are evacuated cylinders capable of liquid transfer.

They have a self-contained power source that requires periodic charging.

3 / 10

Recovering refrigerant from a system in the vapor phase will minimize the loss of which of the following?

oil

refrigerant

water

non-condensables

4 / 10

A passive system-dependent recovery process for small appliances

captures refrigerant in a non-pressurized container

can only be performed on a system with an operating compressor

still uses a pump to recover refrigerant

must use pressure relief device when recovering refrigerant

5 / 10

Why should the oil be removed from a low-pressure system at 130°F

Less refrigerant will be contained in the oil at the higher temperature.

Warmer oil has a lower viscosity and flows more easily.

130°F is the normal operating temperature for oil in a low-pressure system.

it shows that the heater is working

6 / 10

A typical setting for the high pressure cut-out control on a recovery unit used for evacuating the refrigerant from a low-pressure chiller is _______ psig.

7 / 10

In the event of a large release of CFC, HCFC, or HFC refrigerant in a contained area which of the following is true?

Self-contained breathing apparatus (SCBA) or leaving the area is required.

Respiratory protection is not required.

Safety goggles and lined butyl gloves are sufficient

Dust masks are sufficient

8 / 10

How many access valves are needed to recover the refrigerant on a sealed system with an operating compressor that has a completely restricted capillary tube?

Only one access valve, on the low side of the system.

Only one access valve, on the high side of the system.

Two valves, one on the high and one on the low side of the system

Two valves, one at the inlet to the compressor and one at the outlet of the condenser coil.

9 / 10

Where is the rupture disc located on a centrifugal chiller?

Evaporator

Condenser

Liquid line

Economizer

10 / 10

After installation of a field piped split system, the unit should first be pressurized with:

R-410A and leak checked.

nitrogen and leak checked

R-22 and leak checked.

air and leak checked.
