The ODS (Ozone Depleting Substances) Regulations were introduced in the UK in October 2000 and are designed to reduce emissions of ozone depleting substances, which include the refrigerant R22.

The F-Gas Regulation came into force in the UK in July 2008, and its main focus is the containment and recovery of certain fluorinated gases which include R410A (most commonly used refrigerant for Mitsubishi Electric Equipment). The table below shows some of the refrigerants affected by each piece of legislation.


​Refrigerant ​Type ​EU Gas Regulation ​ODS Regulation
R22​ ​HCFC No​ Yes​
R408A​ HCFC + HFC Blend​ Yes​ Yes​
R134A​ HFC​ Yes​ No​
R404A​ HFC Blend​ Yes​ No​
R407C​ HFC Blend​ Yes​ No​
R410A​ ​HFC Blend Yes​ ​No

The list of qualifications for relevant personnel consists of four categories, and includes an outline of what levels of certification are required for each operation: checking for leaks, refrigerant recovery, installation or servicing.

It can be seen that many areas of the ODS and F Gas Regulations overlap. Inspection, maintenance, recordkeeping and use of qualified personnel are all designed to reduce the likelihood of refrigerant leakage. It should also be noted that these are not the only rules driving the requirements for inspections. Under the European Energy Performance of Buildings Directive (EPBD), heat pumps and air conditioning systems of an effective combined rated cooling output of more than 12kW should be regularly inspected.

It is therefore likely to be a company that has responsibility and that organisation will therefore have to ensure that individual staff members who are handling the refrigerant are appropriately qualified.
