In the context of the EPA, the acronym "ODS" stands for Ozone-Depleting Substances. These are chemicals that, when released into the atmosphere, can contribute to the depletion of the ozone layer. The EPA has established regulations and programs aimed at reducing and controlling the emissions of these substances to protect the environment and human health.

Ozone-depleting substances primarily include certain chlorofluorocarbons (CFCs), halons, and other related compounds that are widely used in refrigeration, air conditioning, and aerosol applications. The significance of addressing ODS is rooted in the understanding that the ozone layer plays a critical role in shielding the Earth from harmful ultraviolet radiation.

Understanding the implications of ozone-depleting substances is critical for HVAC professionals who handle refrigerants and other chemicals, as they must be knowledgeable about proper handling procedures and regulatory compliance related to these substances in order to mitigate environmental impacts.
