Yes. R32 is controlled under Australia’s Ozone Protection and Synthetic Greenhouse Gas Management legislation. A refrigerant handling licence (RHL) is required to work on systems containing R32. A refrigerant trading authorisation (RTA) is required to acquire, possess and dispose of R32.
Although R32 has a lower global warming potential compared to other common refrigerants, it is still mandatory to recover this refrigerant from end of life air conditioning and refrigeration systems or during maintenance on the refrigeration circuit.
R32 is a synthetic greenhouse gas. If released to the atmosphere it can contribute to climate change.
