The International Maritime Dangerous Goods Code relates to the safe carriage of dangerous goods by sea, but does not include all details of procedures for packing of dangerous goods or actions to take in the event of an emergency or accident involving personnel who handle goods at sea. These aspects are covered by the publications that are associated with the IMDG Code, which are included in this Supplement.

The Supplement also includes texts of the Medical First Aid Guide, descriptions of the reporting procedures for incidents involving dangerous goods, harmful substances and/or marine pollutants, the International Code for the Safe Carriage of Packaged Irradiated Nuclear Fuel, Plutonium and High-Level Radioactive Wastes on board Ships and other appropriate Assembly resolutions, resolutions and circulars of the Maritime Safety Committee and circulars of the Facilitation Committee and of the Sub-Committee on Dangerous Goods, Solid Cargoes and Containers.
