EPA 608: TYPE II REFRIGERANT MANAGEMENT UPDATED ACTUAL EXAM

EPA 608: TYPE II |REFRIGERANT MANAGEMENT| UPDATED ACTUAL EXAM

1.All liquid has been recovered from a system to be overhauled, the system Should not be opened until all vapor has been recovered Should have air pumped through it and vented to atmosphere before being opened Should be pumped with nitrogen before being opened Can be safely opened and repaired 2.What is the recommended method for charging a refrigeration system to prevent heat exchangers from freezing?Charge the system with refrigerant LIQUID until the pressure is high enough.Charge the system with refrigerant VAPOR until the pressure is high enough.Charge the system with a mixture of refrigerant and water.Charge the system with refrigerant at a temperature below 32°F.

3.Explain why leak detection is a critical step in the management of refrigerants after assembling a new refrigeration system.It helps to improve the cooling efficiency of the system.It prevents environmental harm by ensuring refrigerants do 1 / 4

not escape.It is a regulatory requirement that must be documented.It allows for the immediate use of the system without further checks.

4.A refrigeration technician discovers a substantial leak in a commercial freezer that is currently not in use. The technician decides to mothball the 2 / 4

appliance. What steps should the technician take to ensure compliance with EPA regulations while the appliance is mothballed?Seal the appliance and document the leak, but do not perform any repairs.Perform immediate repairs and document the actions taken.Mothball the appliance and schedule a repair for after the 30- day period.Notify the EPA and ensure the refrigerant is recovered and the system is secured.

5.Explain the significance of having a sensor and alarm for oxygen deprivation in rooms using non-toxic refrigerants as per ASHRAE Standard 15.It ensures the refrigerant is at the correct temperature.It prevents the buildup of toxic gases in the environment.It alerts personnel to potential oxygen shortages that could affect safety.It monitors the efficiency of the refrigeration system.

6.Which of the following is NOT an option for addressing a refrigerant leak if it cannot be adequately fixed?Mothball Retrofit 3 / 4

Replace Repair 7.What is the condition under which the 30-day EPA time period for repairing and testing a substantial leak can be suspended?If the appliance is mothballed
