Regulation 3 Application
Subject to regulation 5(3) below, these Regulations shall apply in respect of serious injuries, dangerous occurrences and hazardous incidents as they apply in respect of accidents, except that regulations 5 and 7 shall not apply to hazardous incidents.
These Regulations apply to accidents involving or occurring on board—
any United Kingdom ship, except that regulation 5 shall not apply to pleasure vessels or to lifeboats operated by the Royal National Lifeboat Institution; and
any other ship within the United Kingdom or the territorial waters thereof, save that regulations 5 and 7 shall not apply to such a ship unless she is within a port in the United Kingdom or is employed in carrying passengers to or from a port in the United Kingdom.
An investigation may be held under regulation 6 into an accident involving or occurring on board a ship which is not a United Kingdom ship and which at the time of the accident was not within the United Kingdom or the territorial waters thereof, if the Secretary of State so determines.
