UN Recommendations on the Transport of Dangerous Goods - Model Regulations
Guiding Principles for the development of the UN Model Regulations
The purpose of the Guiding Principles is to explain the underlying principles that have been applied in developing the UN Recommendations on the Transport of Dangerous Goods, Model Regulations. They may be useful for those intending to apply the Model Regulations in legislation or those who need to explain the purpose of the Regulations or train others in their use to understand the rationale behind their drafting.
The Guiding Principles may be used by regulators and others who intend to submit proposals for revisions to the Model Regulations as an aide-memoire to the approach taken with particular aspects of the Model Regulations.
NOTE: The Guiding Principles are still under development. They DO NOT take precedence over the provisions contained in the Model Regulations themselves. Although these Guiding Principles are normally followed by the Sub-Committee of Experts on the Transport of Dangerous Goods when developing the provisions contained in the Model Regulations, there are instances where the Sub-Committee may have found it necessary to deviate from these principles. Exceptions are not necessarily indicated in this document.
