A Refrigerant Safety Data Sheet (SDS) is a critical document that provides essential information about a specific refrigerant’s physical and chemical properties, potential hazards, safe handling and storage practices, exposure controls, and emergency response measures. Its primary purpose is to enable HVAC professionals to make informed decisions when working with various refrigerants, ensuring safe and responsible use. By understanding the contents of an SDS, technicians can identify potential risks and take necessary precautions to prevent accidents, injuries, and environmental harm.
