All shipboard personnel responsible for the maintenance and repair of air conditioning systems using refrigerants covered under the EPA Clean Air Act venting prohibition, must be certified through an approved Environmental Protection Agency (EPA) program to do which of the following?
• EPA Clean Air Act venting prohibition and which actions are likely to release refrigerant to the atmosphere • What counts as maintenance, service, or repair versus simple operation/adjustment of equipment controls • Difference between actions that might vent refrigerant and actions that are only operating the system
• Which of the listed actions could reasonably be expected to open the refrigerant circuit or cause a leak to the atmosphere? • Is certification required for any contact with the system, or only when there is a risk of releasing regulated refrigerants? • Look at the key regulatory phrase used in EPA rules about technicians handling Class I and Class II refrigerants—does it focus on all work, or only work with potential emissions?
• Identify which choices describe work that could release refrigerant versus normal system operation • Check whether the option mentions Class I or Class II refrigerants and the idea of them being released to the atmosphere • Eliminate any answer that would unrealistically require certification for every minor operational adjustment that does not open the refrigerant system
