What regulations must Michigan mechanical contractors follow when handling refrigerants?

In Michigan, mechanical contractors who handle refrigerants must adhere to a combination of federal and state regulations that govern the use and management of refrigerants. The Environmental Protection Agency (EPA) regulations are pivotal because they set the standard for the safe handling, recovery, and disposal of refrigerants, particularly those that can harm the ozone layer or contribute to global warming. Compliance with EPA standards is crucial for environmental protection and the safety of the public.

Additionally, the Michigan Refrigeration Code provides specific state-level regulations that must be followed. This code outlines the requirements for the installation and maintenance of refrigeration systems, including those that utilize refrigerants. It is designed to ensure that mechanical contractors operate within safe practices and use refrigerants responsibly.

While local municipal codes may play a role in specific building or operational standards within a locality, they are not comprehensive enough to cover all the necessary regulations related to refrigerants. International guidelines may provide additional insights or standards, but they do not supersede the established federal and state regulations that mechanical contractors must follow.

Thus, the combination of EPA regulations and the Michigan Refrigeration Code comprehensively covers the legal framework required for handling refrigerants in Michigan.
