As part of the UK Government’s F Gas Regulation in Great Britain, the use of F gases in certain applications is banned and the rules set requirements for leak checks, leakage repairs and recovery of used gas. In addition, the F gas Regulation requires that all technicians handling F gases must be trained in their safe use and certified.   If you need to service, repair, or dismantle a vehicle's air-conditioning equipment, ensuring that you hold a relevant qualification in refrigerant recovery and handling is crucial. Anyone handling or recovering refrigerants in vehicle air-conditioning equipment requires the correct qualifications to meet minimum requirements. Furthermore, if the vehicle's air-conditioning system contains a chlorofluorocarbon (CFC) such as R12, any maintenance work that involves breaking into the refrigerant circuit should not be carried out. Instead, a specialist business should be used to dispose of equipment containing CFCs and comply with the duty of care for waste.   F-gases should be used with caution, and it is good practice to check vehicle air-conditioning equipment containing F-gases for any leaks before refilling it. Before retrofitting an air-conditioning system that uses an F-gas with a global warming potential of greater than 150, it's crucial to check with the manufacturer or dealer that a vehicle type is approved. Finally, it's important to remember that no car or light van should be retrofitted with an air-conditioning system that contains an F-gas with a GWP of greater than 150.
