Purpose:
The purpose of the article is to review the literature on the risks associated with the transport, storage and processing of liquefied natural gas and to create the basis for developing a methodology for assessing the risk of LNG risks and building procedures for responding to the State Fire Service. In the article, the authors focused on reviewing the threats arising from the physicochemical properties of LNG. The publication refers to the threat scenarios related to the operation of LNG terminals.

Introduction:
The construction of the LNG terminal in Świnoujście, the constantly growing LNG industry on a global scale, as well as the increasingly widespread use of vehicles fueled with this fuel, means that the hypothetical possibility of emerging related risks is growing. Therefore, it is extremely important to be aware of the risks associated with the use of LNG. All corrective/remedial actions require a thorough knowledge of the phenomena they are directed at. The article is the first stage of works on counteracting LNG threats by the fire department as part of creating LNG procedures. The article summarizes the main threats that can be faced by emergency services and scenarios that can be used to build an LNG incident risk assessment methodology.

Methodology:
The analysis presented in the article was prepared based on a review of selected Polish and foreign literature. The global LNG industry and its history, as well as physicochemical properties of liquefied gas, were discussed in general. Hazards resulting from the physicochemical properties of LNG have been indicated. The scenarios of threats to the LNG supply chain appearing in the literature were discussed.

Conclusions:
Based on a synthetic review of the literature, it can be concluded that the risks associated with the use of LNG have been thoroughly described in international literature. In Polish literature, the subject remains discussed in a few publications. Awareness of the risks associated with the use of LNG is crucial for the work of officers of the State Fire Service, as it is the basis for taking all remedial measures against the described risks. At the same time, threat analysis is the first point to assess the risk of LNG-related threats. There are few descriptions of threats in the literature in the micro-scale, i.e. threats resulting from the use of LNG-powered vehicles. Very precisely, and threats have been described on a macro scale, i.e. related to the transport and storage of large quantities of LNG.
