When dangerous goods are transported, the consignment must be accompanied by a transport document declaring the description and nature of the goods. Documentation must be in accordance with the specifications set by the dangerous goods regulations applicable to the chosen mode of transport. The Transport Regulations are tightly regulated due to the potential risks to people and the environment. No matter how they are transported dangerous goods must be identified by way of assignment to one or more of the nine Dangerous Goods classes and subsequent sub-divisions for dangerous goods. The classes relate to the type of hazard present: Dangerous Goods Classes
