7.1 Fluorinated Greenhouse Gas Requirements
Stationary air conditioning, refrigeration, heat pump equipments and stationary fire protection sys-
tems in the European Community market and operating with fluorinated greenhouse gases (f-gas),
such as R407C, R134a, R410A, must comply with the F-Gas Regulation: (EC) No. 842/2006 (F-gas).
The regulation prohibits, among other actions, venting fluorinated greenhouse gases to the atmo-
sphere.
The F-Gas Regulation requires operators to use use all measures that are technically feasible and do
not entail disproportionate cost to prevent leakage of these gases, to test for leakage regularly and to
recover f-gas during equipment service and maintenance and before disposing of equipment.
Refer to the full regulation for additional details.
