Ozone-depleting substances (ODS) and fluorinated gases (F-gases)

ozone depleting substances and f-gases in air-conditioning equipmentThis guidance is for businesses that use or handle ozone-depleting substances (ODS) and fluorinated gases (F-gases). Both are tightly regulated and have restrictions on their production, transport, sale, recovery, recycling and disposal.

 

 


What are ozone-depleting substances (ODS)?

ODS are substances that, if allowed to escape, damage the ozone layer in the upper atmosphere. ODS include chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). Many ODS are banned or being phased out.

You can only produce and market ODS:

  • as a feedstock for producing non-ODS substances, eg Teflon
  • for laboratory and analytical work.

You must not release ODS into the atmosphere.

From 1 July 2010 you must clearly label feedstock ODS and indicate that it can only be used for that purpose.

What are fluorinated gases (F-gases)?

F-gases are a family of gases containing fluorine. They are often used as a replacement for ODS. F-gases are powerful greenhouse gases that trap heat in the atmosphere and contribute to global warming. Their use is strictly regulated.

Common uses for ODS and F-gases include:

  • refrigeration and air-conditioning equipment
  • aerosols
  • solvents
  • foam blowing agents
  • firefighting fluids
  • high voltage switch gear.
