Final answer:
Automotive air-conditioning technicians must obtain a 609 license from the EPA, which requires passing an approved test that covers refrigerant recovery and handling. This certification ensures technicians can work safely and legally with automotive air-conditioning systems.
Explanation:
Automotive air-conditioning service and repair technicians need to have a 609 license to legally work on automotive air-conditioning systems. This certification is required by the Environmental Protection Agency (EPA) because automotive air-conditioning systems contain refrigerants that can be hazardous to the environment if not properly handled. Technicians must pass an EPA-approved test to earn their 609 certification, which covers topics like refrigerant recovery, recycling, and proper handling procedures.
Unlike options A and B, the 609 license specifically relates to the environmental and health safety aspects of handling vehicle air-conditioning refrigerants. Option D is incorrect because a specific license is indeed required. This certification ensures that technicians have the necessary knowledge and skills to prevent the release of refrigerants into the atmosphere, helping to protect the environment and comply with legal requirements.
