CLP Regulation and the transport of dangerous goods.

Regulations concerning different modes of transport of dangerous goods are well harmonized at global level: they were then looked at as a model for developing Globally Harmonized System of Classification and Labelling of Chemicals (GHS), (on which CLP Regulations is based). Transport regulations do not cover some hazard classes, such as germ cell mutagenicity, carcinogenicity, reproductive toxicity, having been evaluated that such hazards are not relevant in transport because in general, in case of accident, no repeated and prolonged exposure takes place. Other differences with CLP Regulation are related to the use of "building block approach". Transport labels, which were used as a basis for GHS, can be used, instead of CLP pictograms, on packages during transport.
