F-Gas Regulations
The regulations for F-Gas were introduced to assist in reducing higher GWP gases. The regulation includes the phasing out of HFCs by reducing quotas and banning certain products.
F-Gases are a collection of manufactured gases which are used in a wide range of industrial, commercial and domestic applications. These include systems such as refrigeration, air conditioning, solvents, and aerosols.
These regulations will affect those that manufacture, use or service any equipment containing F-Gas. It will also affect those that produce, sell, import, and export F-Gas.
Refrigeration and Air conditioning equipment require mandatory documented leak detection checks according to how much damage could be caused to the atmosphere if the charge leaked. The frequency of inspection intervals is dictated by the GWP of the refrigerant multiplied by the estimated volume contained in each system. This will provide you with the CO2e figure.

Inspection Guidelines?
The system will need an annual inspection if it contains between 5 and 50 tonnes of CO2e.
Between 50 to 500 tonnes of CO2e requires an inspection every six months.
Greater than 500 tonnes of CO2e require a quarterly inspection.
These inspection intervals can be reduced by half if a permanent gas leak system is installed. Fixed refrigerant leak detection systems are compulsory for a system with a charge greater than 500 tonnes CO2e equivalent and above.
A system containing R410a (2088 GWP) with more than 2.39kg must be checked once a year, 23.9kg twice a year, and more than 239kg needs four checks per year.
A system containing R134a (1430 GWP) more than 3.49kg once a year, 34.9kg twice a year and over 349kg four times a year.
For other refrigerants, it is 5000 divided by its GWP to get the first inspection’s visit weights, then move the decimal place one to the right to get the rest. (As described above).
