2005-2006 Program of Work for the United Nations Transport of Dangerous Goods
Sub-Committee
The United Nations Transport of Dangerous Goods Sub-Committee (TDG Sub-Committee) will meet four times during the 2007-2008 biennium and plans to address a number of issues. PHMSA encourages the public to participate in the work of the TDG Sub-Committee and to comment on the work items. Comments may be provided to Mr. Duane Pfund at (202) 366-0656 or by email at duane.pfund@dot.gov.
The following are the meeting dates scheduled for the 2005-2006 biennium:
- 21st Meeting of the ICAO Dangerous Goods Panel, November 5-16, 2007, Montreal, Canada
- 32nd session of the TDG Sub-Committee, December 3-12, 2007, Geneva, Switzerland
The primary topics which the TDG Sub-Committee plans to address during the 2007-2008 biennium include:
- Performance of packagings, including IBCs – The topic of packaging of hazardous materials is one that generally remains on the TDG Sub-Committee's agenda. While the packaging requirements are fairly mature the Sub-Committee consistently strives to introduce incremental improvements to enhance the safety by ensuring the integrity of packagings.
- Limited quantities (multimodal harmonization) – The TDG Sub-Committee is expected to consider requirements for consumer commodities with the goal of harmonizing these requirements in the 2007-2008 biennium.
- Electronic Data Interchange for documentation purposes – The Sub-Committee is considering amending language in the UN Model Regulations to allow electronic communication of hazards to supplement paper documents.
- Harmonization with IAEA Regulations for the Safe Transport of Radioactive Material - The Sub-Committee agreed to consider further harmonization of terminology used for dangerous goods and radioactive material requirements.
- Issues relating the Globally Harmonized System of Classfication and Labelling of Chemicals (GHS) – Listing and classification is a topic that is always on the TDG Sub-Committee's agenda. New data relevant to the classification of certain chemicals is periodically submitted to the Sub-Committee for consideration. It is also anticipated that the minor amendments to classification criteria that will result through the adoption of the GHS will also lead to the reclassification of some hazardous materials (e.g. those with an oral toxicity greater than 300 mg/kg).
- Miscellaneous amendments to the Model Regulations, as necessary
