30.Section 7 provides that sections 3 and 5 of the Act apply to the whole of the United Kingdom. The rest of the Act generally only applies to Great Britain. Part I of the 1990 Act also generally only applies to Great Britain but section 3(5) to (7) in that Part also applies to Northern Ireland. The repeal of Part I of the 1990 Act will not affect section 3(5) to (7) in so far as it applies to Northern Ireland.
31.Section 7(9) will enable regulations under the Act to apply to installations under the jurisdiction of the United Kingdom but beyond its territorial waters. This will enable, for example, the regulation of large combustion installations on oil rigs whether or not they are in territorial waters.
