Which key document must be obtained to handle refrigerants legally?

To handle refrigerants legally, obtaining EPA certification is crucial. The Environmental Protection Agency (EPA) regulates the handling of refrigerants to minimize their impact on the environment, particularly concerning ozone depletion and climate change. This certification ensures that individuals are trained in proper handling practices, including leak detection, recovery, recycling, and safe disposal of refrigerants. It verifies that the individual understands the laws and regulations governing refrigerants and can handle them responsibly and safely.

While other documents like an environmental assessment report or a local license may be relevant in specific contexts, they do not specifically address the training and legal qualifications required for handling refrigerants under federal law. The refrigerant handling certificate is often tied to specific training programs that may lead to EPA certification, but without the EPA certification, one would not be compliant with federal regulations. Thus, having the EPA certification is the essential requirement for legally managing refrigerants.
