Due to the developing technology and increasing world population, the need and dependence on dangerous goods is increasing in every sector. Dangerous goods have multiple load classes and each load class has one or more hazards specific to itself. Dangerous goods are called dangerous goods when they are sent from the places where they are produced or processed by transport types to the requested places. When the contents of the transported dangerous goods are examined, crude oil and petroleum products are in the first place, chemical substances, oxidising agents, radioactive substances and biological cargoes. Maritime transport is highly preferred for the transport of dangerous cargoes in the safest and most economical dimensions. Container transports have been increasing especially in recent years. Container terminals have become very important transit points for dangerous cargo transports. During the operation of dangerous cargoes within the boundaries of the terminal, there are dangers of explosion, fire as a result of flare, spread and injury and death of port personnel, sea and environmental pollution. The Marmara region is very important in geopolitical and strategic terms because it is the most populous region in terms of population density and because it is home to the Istanbul and Dardanelles straits, which are among the most straits in the world. In addition, due to the danger of the expected great Istanbul earthquake, the ports of the Marmara region have been focused on. After the movement of the great earthquake fault line, which is claimed to pass through the Marmara Sea, there are great risks for the surrounding civilian population after possible accidents after the earthquake in the ports operating in the Marmara region. In this study, the operations of dangerous cargoes within the terminal boundaries in container terminals operating in the Marmara region were analysed. These operations are grouped into five main criteria and they are grouped as entry operation, storage operation, handling operation and emergency operation. In the light of the determined criteria, the importance given to container terminals, dangerous cargo transports in terms of safety in which operations and which type of cargo is prioritised in terms of safety are determined by Analytical Hierarchy Process (AHP) method. In the data obtained, it has been observed that most of the terminals have priorities in terms of human life, environmental pollution and marine pollution within the scope of emergency operations occurring within the terminal and that they give priority to gas cargoes in terms of safety.
