In modern maritime transport, the transport of dangerous goods is increasingly taking place, which can potentially lead to significant pollution or danger to human lives and the environment. It is therefore necessary to provide special provision for ships carrying dangerous goods, depending on the type of goods being transported and the environmental and safety regulations laid down at national and international level. The transport of dangerous goods is the transport of material that is legally recognized as dangerous by various special means of transport, because the properties of cargo pose a danger to people or vessels during transport. Maritime transport of dangerous goods in containers follows special rules that are precisely formulated in the IMDG Code as well as the SOLAS Convention. The transport of dangerous goods must ensure safe and harmonized transport. The transport of dangerous goods without the necessary documentation, specialized equipment and training is illegal and punishable, and such a ship is not allowed to enter territorial waters.
