Dangerous Goods

Any goods that may potentially endanger people, property or the environment are classified as “dangerous”. Such goods are being transported all over the globe around the clock with a large collection of regulations that must be followed. Additionally, there are comprehensive national and international laws, guidelines and agreements,in which the conditions for classification, identification, packing, the technical equipment to be used for dangerous goods transportation are precisely explained. Furthermore, organizational procedures, obligations and accountabilities of the people concerned with the transport process are also specified.

Separate regulations exist for each individual transport mode: rail, road, inland shipping, ocean shipping, air transport but they have been gradually harmonized.

Regulations are regularly amended to match new constraints and developments. Knowledge acquired as a result of studying actual incidents related to dangerous goods is used to improve the regulations and prevent future incidents.
