These Regulations provide derogations from the end date for the use of halon 1211, in Regulation (EC) 1005/2009 of the European Parliament and of the Council on substances that deplete the ozone layer (recast) (“the Ozone-Depleting Substances Regulation”). The Ozone-Depleting Substances Regulation is assimilated law. The derogations provide new end dates which extend the period for the use of halon 1211 in portable fire extinguishers for the protection of cabins and crew in specified Defence and Loganair aircraft.
