The Code applies to ships regardless of their size@ including those of less than 500 tons gross tonnage@ engaged in the carriage of liquefied gases having a vapour pressure exceeding 2.8 bar absolute at a temperature of 37.8OC@ and other products as shown in chapter 19@ when carried in bulk. Unless expressly provided otherwise@ the Code applies to ships the keels of which are laid or which are at a stage at which: construction identifiable with the ship begins; and assembly of that ship has commenced comprising at least 50 tonnes or 1% of the estimated mass of all structural material@ whichever is less; on or after 1 October 1994. Ships constructed before I October 1994 are to comply with resolution MSC.5(48) adopted on 17 June 1983. A ship@ irrespective of the date of construction@ which is converted to a gas carrier on or after 1 July 1986@ should be treated as a gas carrier constructed on the date on which such conversion commences. When cargo tanks contain products for which the Code requires a type I C ship@ neither flammable liquids having a flashpoint of 6OoC (closed cup test) or less nor flammable products listed in chapter 19 should be carried in tanks located within the protective zones described in 2.6.1.1. Similarly@ when cargo tanks contain products for which the Code requires a type 2C/2PG ship@ the above-mentioned flammable liquids should not be carried in tanks located within the protective zones described in 2.6.1.2. In each case the restriction applies to the protective zones within the longitudinal extent of the hold spaces for the cargo tanks loaded with products for which the Code requires a type I C or 2C/2PC ship. The above-mentioned flammable liquids and products may be carried within these protective zones when the quantity retained in the cargo tanks of products for which the Code requires a type I C or 2G/2PG ship is solely used for cooling@ circulation or fuelling purposes. Except as provided in 1.1.7.1@ when it is int??nded to carry products covered by this Code and products covered by the International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk adopted by the Maritime Safety Committee under the authority of the Assembly of the Organization conferred by resolution A.490(Xll)@ as may be amended by the Organization (IBC Code)@ the ship should comply with the requirements of both Codes appropriate to the products carried. Where it i s proposed to carry products which may be considered to come within the scope of the Code but are not at present designated in chapter 19@ the Administrations and the port Administrations involved in such carriage should establish preliminary suitable conditions of carriage based on the principles of the Code and notify the Organization of such conditions. The requirements of this Code should take precedence when a ship i s designed and constructed for the carriage of the following products: those listed exclusively in chapter 19 of this Code; and one or more of the products which are listed both in this Code and in the International Bulk Chemical Code. These products are marked with an asterisk in column a in the table of chapter 19. When a ship is intended exclusively to carry one or more of the products noted in 1.1.7.1.2@ the requirements of the International Bulk Chemical Code as amended should apply. Compliance of the ship with the requirements of the International Gas Carrier Code should be shown in the International Certificate of Fitness for the Carriage of Liquefied Gases in Bulk provided for in 1.5. Compliance with the amendments to the Code@ as appropriate@ should also be indicated in the International Certificate of Fitness for the Carriage of Liquefied Gases in Bulk.
