GB Health & Safety legislation, including RIDDOR does not have jurisdiction in other countries, I.e. Outside GB

There is also some useful guidance in relation to the MOD. The advice is that the application of HSWA etc abroad is slightly more complex than Jay suggests and is referred to here;

http://www.hse.gov.uk/se...ces/armedforces/faqs.htm

"British health and safety legislation only applies within the baseline of Great Britain (GB), to certain offshore facilities and to certain other activities within territorial waters, subject to the Health and Safety at Work etc Act 1974 (Application Outside Great Britain) Order 2001 link to external website. It does not apply to activities outside of these areas, so it will not apply to military operations abroad or to British bases in Gibraltar, Cyprus or Germany for example.

HSE does not investigate any incidents occurring outside GB.

HSE may however consider relevant information about incidents occurring outside GB - not for the purposes of investigating the incident itself - but in relation to any learning that is applicable to similar activities that take place in GB because such incidents may be indicative of breaches within GB, where the Act is applicable.

Where there is an incident resulting in significant exposure to risk outside HSE's jurisdiction as a result of decisions made in GB, HSE will not be responsible for investigating those decisions /activities if no risk arises in relation to employees at work in GB or to other persons in GB. Risks outside of GB may be subject to the legislation of the country where that risk arises..."

NB some UK legislation has wider application, ie in Merchant Shipping and Civil Aviation. The regulators for these areas of law have UK wide powers, and the laws themselves can have limited application worldwide.
