Two technicians are discussing refrigerant removal. Technician A says that all refrigerant must be captured. Technician B sa you can vent refrigerant into the atmosphere as long as it contains moisture. Who is correct? A. Technician B B. Both Technicians A and B C. Technician A D. Neither Technician A nor B
The Correct Answer and Explanation is :
The correct answer is C. Technician A.
Explanation:
When it comes to refrigerant removal, the Environmental Protection Agency (EPA) and other regulatory bodies enforce strict guidelines to prevent harm to the environment. Specifically, refrigerants like CFCs (chlorofluorocarbons), HCFCs (hydrochlorofluorocarbons), and HFCs (hydrofluorocarbons) can contribute to ozone depletion and climate change, which is why refrigerant handling and disposal are highly regulated.
- Technician A’s Statement: “All refrigerant must be captured” is correct.
- According to the EPA’s regulations under Section 608 of the Clean Air Act, refrigerants must not be vented into the atmosphere. They must be recovered using proper recovery equipment. This includes refrigerants that may be removed from air conditioners, refrigerators, and other systems. Even if the refrigerant contains moisture, it still must be recovered and handled using specialized recovery equipment to avoid environmental damage.
- Technician B’s Statement: “You can vent refrigerant into the atmosphere as long as it contains moisture” is incorrect.
- Venting refrigerant into the atmosphere, even if it contains moisture, is strictly prohibited by EPA regulations. Moisture or water content in refrigerants does not make it permissible to vent them. The focus is on preventing harmful gases from entering the atmosphere. Technicians must recover refrigerants and either recycle or safely dispose of them according to EPA-approved methods. Even if the refrigerant is contaminated, venting is not an option.
Why Technician A is correct:
- Legal Requirements: Technician A is correct because the law mandates that all refrigerants be recovered, regardless of their condition. The goal is to reduce the release of substances that can contribute to ozone depletion or global warming.
- Best Practices: Technicians are required to use recovery machines to capture refrigerants, and it is illegal to intentionally release them into the air, as this would contribute to environmental damage.
In summary, Technician A correctly describes the process of refrigerant removal, whereas Technician B’s statement contradicts EPA guidelines.
