Regulation 4 MARKING AND LABELLING Each receptacle containing dangerous goods shall be marked with the correct technical name (trade names shall not be used) and identified with a distinctive label or stencil of the label so as to make clear the dangerous character. Each receptacle shall be so labelled except receptacles containing chemicals packed in limited quantities and large shipments which can be stowed, handled and identified as a unit. Regulation 5 DOCUMENTS (a) In all documents relating to the carriage of dangerous goods by sea where the goods are named the correct technical name of the goods shall be used (trade names shall not be used) and the correct description given in accordance with the classification set out in Regulation 2 of this Chapter (b) The shipping documents prepared by the shipper shall include, or be accompanied by, a certificate or declaration that the shipment offered for carriage is properly packed, marked and labelled and in proper condition for carriage. (c) Each ship carrying dangerous goods shall have a special list or manifest setting forth, in accordance with Regulation 2 of this Chapter, the dangerous goods on board and the location thereof. A detailed stowage plan which identifies by class and sets out the location of all dangerous goods on board may be used in place of such special list or manifest. Regulation 6 TEMPORARY EXCEPTIONS TO REGULATIONS 4 AND 5 Contracting Governments which have a uniform system of rules for land and sea transport relating to the carriage of dangerous goods and cannot therefore immediately apply the provisions of Regulations 4 and 5 of this Chapter may authorise departures from the provisions of those Regulations for a period not - exceeding twelve months from the date on which the Convention comes into force, provided that dangerous goods as classified in Regulation 2 of this Chapter are also so classified in the shipping documents and are labelled accordingly. Regulation 7 STOWAGE REQUIREMENTS (a) Dangerous goods shall be stowed safely and appropriately according to the nature of the goods. Incompatible goods shall be segregated from one another. (b) Explosives (except ammunition) which present a serious risk shall be stowed in a magazine which shall be kept securely closed while at sea. Such explosives shall be segregated from detonators. Electrical apparatus and cables in any compartment in which explosives are carried shall be designed and used so as to minimise the risk of fire or explosion. (c) Goods which give off dangerous vapours shall be stowed in a well ventilated space or on deck. (d) In ships carrying inflammable liquids or gases special precautions shall be taken where necessary against fire or explosion. (e) Substances which are liable to spontaneous heating or combustion shall not be carried unless adequate precautions have been taken to prevent the outbreak of fire. Regulation 8 EXPLOSIVES IN PASSENGER SHIPS (a) In passenger ships the following explosives only may be carried: (i) safety cartridges and safety fuses; (ii) small quantities of explosives not exceeding 20 pounds (or 9 kilograms) total net weight; (iii) distress signals for use in ships or aircraft, if the total weight of such signals does not exceed 2,240 pounds (or 1,016 kilograms); (iv) except in ships carrying unberthed passengers, fireworks which are unlikely to explode violently. (b) Notwithstanding the provisions of paragraph (a) of this Regulation additional quantities or types of explosives may be carried in passenger ships in which there are special safety measures approved by the Administration.
