Any person who sells or distributes any Class I or Class II refrigerant, in a __, must verify that the purchaser is properly trained, that the purchaser is 609 Certified, and must retain a record of the purchase.
A) Container holding more than 20 Pounds
B) Container holding less than 20 Pounds
C) Container holding 20 Pounds
D) Approved disposable container
The correct answer and explanation is :
Correct Answer:
A) Container holding more than 20 Pounds
Explanation:
The Environmental Protection Agency (EPA) regulates the sale and distribution of refrigerants under Section 608 and 609 of the Clean Air Act to minimize emissions that contribute to ozone depletion and climate change.
Understanding Class I and Class II Refrigerants:
- Class I refrigerants include CFCs (Chlorofluorocarbons) like R-12, which have been phased out due to their high ozone depletion potential.
- Class II refrigerants include HCFCs (Hydrochlorofluorocarbons) like R-22, which are being phased out as part of environmental protection efforts.
Why Verification is Required?
- The EPA mandates that any individual purchasing Class I or Class II refrigerants in containers larger than 20 pounds must provide proof of proper training and certification.
- This requirement ensures that only trained professionals handle these substances, reducing accidental releases and improper disposal that could harm the environment.
- Under Section 609 certification, technicians working on motor vehicle air conditioning (MVAC) systems must be certified before purchasing these refrigerants.
Record-Keeping Responsibilities
- Sellers must verify and retain records of the purchaser’s 609 certification to prove compliance with federal regulations.
- Failure to maintain these records can result in significant fines and legal penalties under the Clean Air Act.
Why Containers Larger than 20 Pounds?
- Smaller containers (less than or equal to 20 pounds) are often used for small-scale applications, and regulations may be slightly different for them.
- Larger containers are usually used by commercial and industrial technicians, where the risks of improper handling are greater.
Conclusion:
Purchasing Class I or Class II refrigerants in containers larger than 20 pounds requires proper certification and verification. These regulations ensure responsible refrigerant handling to protect both the ozone layer and the environment.
