MERCHANT SHIPPING (SAFETY) (DANGEROUS GOODS AND MARINE POLLUTANTS) REGULATION
Marking and labelling
(1) Dangerous goods or marine pollutants which are contained in a package shall not be taken on board a ship for carriage in that ship unless the conditions in this section are satisfied.
(2) (a) Packages containing dangerous goods or marine pollutants shall be durably marked in accordance with the IMDG Code.
(b) Packages containing dangerous goods or marine pollutants shall be provided with labels or stencils of labels or placards where specified in the IMDG Code.
(c) The method of marking the correct technical name and of affixing labels or applying stencils of labels or placards on packages containing dangerous goods or marine pollutants shall be such that the information marked, affixed or applied will remain legible after the package has been immersed for 3 months in the sea or, if the package itself disintegrates before the end of that period, for as long as the package will last. Where the outer material of the package is such that it will not survive at least 3 months' immersion in the sea, any inner receptacles which will survive such immersion shall be durably marked with an indication of the nature of the danger to which the goods give rise, which indication may be given by any suitable means including (but not restricted to) an IMDG Code Class symbol or marine pollutant mark, or both, of an appropriate size.
(d) Without prejudice to the above requirements, where the goods are contained in a freight container, vehicle, portable tank or tank container, the cargo transport unit in which the goods are contained shall bear conspicuously on its exterior distinctive placards or other appropriate marking, in accordance with the IMDG Code.
(3) Any breach of the requirement of this section relating to the marking, labelling or placarding of packaged goods shall be an offence on the part of the shipper of those goods.
(4) A shipowner or master who accepts dangerous goods or marine pollutants to be taken on board a ship in any package which has not been marked and labelled, or placarded as provided for in this section commits an offence.
