Question

Quizplus · Accepted Answer

Both Technician A and Technician B are correct. Technicians working with R-12 air-conditioning systems must be certified to ensure they understand how to properly handle and dispose of the refrigerant, which is a chlorofluorocarbon (CFC) and harmful to the ozone layer. Additionally, the equipment used in servicing R-12 systems must also be certified to ensure it meets environmental safety standards and does not release CFCs into the atmosphere.
