United Nations Classification Dangerous

Hazardous materials in the broad sense are materials having hazards such as combustibility, explosiveness, corrosiveness and toxicity. The concept is represented by the United Nations Recommendation on the Transport of Dangerous Goods. This classification has been adopted with almost no change in the IMDG-Code and...

The basis for the classification of explosives throughout the world is based upon conventions developed by the United Nations committee (UNO) on Transport of Dangerous Goods [5]. 

Substances Act). The classification of psilocybin, psilocin, and many other entheogens as dangerous drugs is primarily based on socio-political reasons rather than clinical-scientific evidence. Psilocybin, psilocin, and DMT are also internationally classified as Schedule 1 substances by the 1971 United Nations Convention on Psychotropic Substances. 

United Nations Committee on Transport of Dangerous Goods and the U.S. Department of Transportation use a classification system, outlined in Appendix C that does not completely correlate with the systems previously described. Furthermore, this system applies to the transportation of commodities and was not intended to be applied to the warehouse environment. It is intended to give an at-a-glance identification of the hazards much like the NFPA 704 and the NPCA Hazardous Materials Identification System. 

The various hazard classification and chemical risk assessment systems reviewed above are designed in general with the end user of the chemical in mind. However, one of the oldest and best known chemical classification systems in the world is the United Nations (UN) Recommendations on the Transport of Dangerous Goods, first published in 1956 [23]. 

In 1956, a classification system for hazardous goods was established by a committee of the United Nations (UN). This framework represents the starting point for international transportation legislation. The List of dangerous goods most commonly carried was developed by ECOSOC (Economic and Social Council) see Figure 7.2.

Different classification and labelling systems for the hazards of substances are currently used throughout the world. The same substance may thus be classified as toxic in the United States, harmful in the European Union and moderately dangerous in China. To eliminate disparities a Globally Harmonised classification and labelling System (GHS) was developed under the auspices of the United Nations. It was formally adopted in 2002 by the United Nations Economic and Social Committee (UN ECOSOC) and revised in 2005 and 2007 [78, 79].
