UN (ECOSOC) Sub-Committee of Experts on the Transport of Dangerous Goods

In order to ensure consistency between all of the regulatory systems across the globe, the United Nations Economic and Social Council (ECOSOC) developed the UN Sub-Committee of Experts on the Transport of Dangerous Goods.  This group developed mechanisms for the global harmonization for transport conditions in all modes. 

The group is responsible for the UN Model Regulations, which aim to present a basic scheme of provisions that will allow uniform development of national and international regulations govering the various modes of transport; yet they remain flexible enough to accomodate any special requirements that might have to be met.  It is expected that governments, intergovernmental organizations and other international organizations, when revising or developing regulations for which they are responsible, will conform to the principles laid down in these Model Regulations, thus contributing to worldwide harmonization in this field.

UN (ECOSOC) Sub-Committee of Experts on the Globally Harmonized System (GHS)

Given the reality of the extensive global trade in chemicals and the need to develop national programs to ensure their safe use, transport and disposal, it was recognized that an internationally-harmonized approach to classification and labelling would provide the foundation for such programs. Once countries have consistent and appropriate information on the chemicals they import or produce in their own countries, the infrastructure to control chemical exposures and protect people and the environment can be established in a comprehensive manner.

The new system is called "Globally Harmonized System of Classification and Labelling of Chemicals (GHS)", addresses classification of chemicals by types of hazard and proposes harmonized hazard communication elements, including labels and safety data sheets. It aims at ensuring that information on physical hazards and toxicity from chemicals be available in order to enhance the protection of human health and the environment during the handling, transport and use of these chemicals. The GHS also provides a basis for harmonization of rules and regulations on chemicals at national, regional and worldwide level, an important factor also for trade facilitation.

In order to ensure consistency between all these regulatory systems, the United Nations has developed mechanisms for the harmonization of hazard classification criteria and hazard communication tools (GHS).

ICAO Dangerous Goods Panel

Dangerous goods are carried regularly and routinely by air all over the world. To ensure that they do not put an aircraft and its occupants at risk, there are international Standards that each State, under the provisions of the Chicago Convention, is required to introduce into national legislation. This system ensures governmental control over the carriage of dangerous goods by air and gives worldwide harmonization of safety standards.

Annex 18 deals with the Safe Transport of Dangerous Goods by Air and sets down board principles; one of the Standards, however, requires that dangerous goods be carried in accordance with the Technical Instructions for the Safe Transport of Dangerous Goods by Air (the “ICAO Technical Instructions). States are required by Annex 18 to have inspection and enforcement procedures in place to ensure that dangerous goods are being carried in compliance with the requirements.

The Technical Instructions contain a comprehensive set of requirements; among other things, they provide for the classification of dangerous goods and list these goods.

DGAC has observer status on the ICAO Dangerous Goods Panel and regularly attends the ICAO DGP Meetings.

International Maritime Dangerous Goods Code (IMDG Code)

The International Maritime Dangerous Goods (IMDG) Code was developed as a uniform international code for the transport of dangerous goods by sea covering such matters as packing, container traffic and stowage, with particular reference to the segregation of incompatible substances.

Amendments to the IMDG Code originate from two sources; proposals submitted directly to IMO by Member States and amendments required to take account of changes to the United Nations Recommendations on the Transport of Dangerous Goods which sets the basic requirements for all the transport modes.

DGAC participates on various IMO Sub-committees that affect the IMDG Code.

Sub-Committee on Bulk Liquids and Gases (BLG)

the Sub-Committee on Bulk Liquids and Gases (BLG) will consider matters related to the following subjects, including the development of any necessary amendments to relevant conventions and other mandatory and non-mandatory instruments, as well as the preparation of new mandatory and non-mandatory instruments, guidelines and recommendations, for consideration by the Committees, as appropriate, including the role of such measures for the protection of the marine environment:

  • Prevention and control of marine pollution from ships and other related maritime operations involved in the transport and handling of oil and dangerous and noxious liquids substances in bulk;
  • Evaluation of hazards of dangerous and noxious liquid substances in bulk transported by ships;
  • Control and management of ships’ ballast water and sediments;
  • Construction, equipment and operational requirements for ships carrying bulk liquids and gases;
  • Protection of personnel involved in the transport of bulk liquids and gases; and
  • Survey and certification of ships constructed to carry bulk liquids and gases.
