Air Pollution
Ozone Depleting Substances

The use of ozone depleting substances is controlled to ensure that their potential environmental effects, including air pollution, are mitigated. A summary of potential ozone depleting substances is provided below, however this is not a complete list and the Regulations must be referred to for further guidance.
 
Refrigerants:
  • CFCs: 11, 12, 13, 113, 114, 500, 502, 503
  • HCHCs: 22, 123, 124
  • HCFC blends: including R401a, R402a, R403a, R406a, R408a, R411b
Fire Fighting Fluids:
  • Halons: 1211, 1301
The Regulations require that:
  • The supply and use of CFCs is banned from October 2000 [certain exemptions apply, guidance should be sought from ORM]
  • The use of HCFCs for the manufacture of new refrigeration and air conditioning systems is banned.
  • There will be a ban on the use of HCFCs for maintenance and servicing of refrigeration and air conditioning systems from 1st January 2010 and a ban on the use of all HCFCs from 1st January 2015.
  • Halons cannot be used for refilling existing fire protection systems.
Note: mandatory decommissioning of fire protection system and fire extinguishers containing halons must have been completed.
 
In order to ensure compliance with the Regulations aan identified responsible person must ensure that controls are in place to ensure:
  • A refrigerant register is maintained at all BBC premises that can be used to demonstrate that no-venting / escape of ozone-depleting substances has occurred.
  • A suitably qualified contractor  is employed for the servicing and maintenance of refrigeration and air conditioning system to prevent any leakage [this must be undertaken at least annually where the fluid charge is greater than 3 kg].
  • The contractor maintaining the equipment takes all necessary steps to recover and recycle ozone-depleting substances during the maintenance process.
  • The contractor complies with the Duty of Care when disposing of equipment containing ozone depleting substances.
