Regulations for the Prevention of Regulations for the Prevention of Pollution by Harmful Substances Pollution by Harmful Substances Carried by Sea in Packaged FormCarried by Sea in Packaged Form

GeneralGeneral

• Entry into force:1 July 1992

• Apply to all ships carrying harmful substances in packaged form

GeneralGeneral• The Marine Environment Protection Committee (MEPC) at its 55th

session in October 2006 adopted the revised MARPOL Annex III Regulations for the prevention of pollution by harmful substances carried by sea in packaged form. The Annex has been revised to harmonize the regulations with the criteria for defining marine pollutants which have been adopted by the UN Transport of Dangerous Goods (TDG) Sub-Committee, based on the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS).

• The regulations were developed in order to identify marine pollutants so that they could be packed and stowed on board ship in such a way as to minimise accidental pollution as well as to aid recovery by using clear marks to distinguish them from other (less harmful) cargoes.

DEFINITIONS

• “Harmful substances” are those substances which are identified as marine pollutants in the International Maritime Dangerous Goods Code (IMDG Code)

• “Packaged form” is defined as the forms of containment specified for harmful substances in the IMDG Code.

MARKING AND LABELLINGMARKING AND LABELLING

Packages containing a harmful substance shall be durably marked with the correct technical name (trade names alone shall not be used) and, further, shall be durably marked or labelled to indicate that the substance is a marine pollutant

An Introduction to the IMDG An Introduction to the IMDG CodeCode

The objective of the International Maritime Dangerous Goods (IMDG) Code is to:

• Enhance the safe transport of dangerous goods

• Protect the marine environment

• Facilitate the free unrestricted movement of dangerous

goods

The International Legal The International Legal FrameworkFramework

To supplement the principles laid down in the SOLAS and MARPOL Conventions, the IMO developed the International Maritime Dangerous Goods (IMDG) Code.

The IMDG code contains detailed technical specifications to enable dangerous goods to be transported safely by sea.

The IMDG Code became mandatory for adoption by SOLAS signatory states from 1st January 2004.

Principles of the IMDG CodePrinciples of the IMDG CodeThe IMDG Code is based on an internationally agreed system which:

• Groups dangerous goods together based on the hazards they present in transport (classification).

• Contains the dangerous goods in packagings/tanks which are of

appropriate strength and which will prevent the goods escaping.

• Uses hazard warning labels and other identifying marks to identify

dangerous goods in transport.

Principles of the IMDG CodePrinciples of the IMDG Code

• Requires standard documentation to be provided when dangerous goods are being transported.

• Lays down principles for ensuring that dangerous goods which will react dangerously together are kept apart.

• Lays down principles for where to place dangerous goods on board ship to ensure safe transport.

• Provides emergency response advice for dangerous goods involved in a fire or spillage on board ship.

Principles of the IMDG CodePrinciples of the IMDG Code

The IMDG Code is evolving and is updated every two years to take account of:

• New dangerous goods which have to be included.

• New technology and methods of working with or handling

dangerous goods.

• Safety concerns which arise as a result of experience.
