1). Get 300ml of milk and 2 large free range eggs out of your fridge.

F gas is common in refrigeration systems as well as air conditioning, heat pump systems and fire suppression systems. Check to see if your equipment contains F gas and then check the gas against the list of regulated F gases by clicking here

2). Whisk the milk and eggs with 100g of flour and a pinch of salt.

From 2017, equipment where F gas is added must be labelled with:

  • the mass of the F gas in the equipment
  • the CO2 equivalent mass of the F gas in the equipment (in tonnes) – this can be calculated by multiplying the mass of the gas (in tonnes) by the F gas global warming potential
  • the global warming potential of theF gas
  • If f gas is hermetically sealed in a product  


3). Set a non-stick frying pan over a medium heat and cook the pancakes until golden – now flip!

Check for leaks. All equipment must be checked for leaks, and some equipment must be checked at specific intervals. The thresholds for leak check intervals are expressed in CO2 equivalents:

Maximum interval between leak checks CO2 equivalent (tonnes)

  • 1 year         5
  • 6 months    50
  • 3 months    500


Automatic leak detection systems allow the maximum interval between leak checks to be doubled. You must fit a leak detection system if the equipment is equivalent to more than 500 tonnes of CO2.

4). Serve with lemon and sugar!

Records must be kept for 5 years and this should also include a record of disposing of equipment containing F gas, recycling and recovering of gas. Over the coming years there are bans and phase downs of F gases, so make sure you plan for this.

Enjoy!
