CBRN events in the subway system of Rome: technical-managerial solutions for risk reduction

The acronym CBRN stands for Chemical, Biological, Radiological and Nuclear CBRN risks are those caused by chemical, biological, radiological or nuclear agents that can produce serious harm to persons and things. The accidents connected with this type of substances can be either due to man (industrial accidents, road accidents, human mistakes in manipulation and/or storage of materials, etc.) or natural causes, when the structures where these substances are produced or stored are damaged by natural events (earthquakes, flood, etc.). Sometimes, in cases of terrorism, man voluntarily causes this kind of incidents. In Italy, as well as in the rest of the world, subways are one of the critical infrastructures that are more at risk in case of a CBRN event. In this work, the authors will analyse the case study of the subway system of Rome and propose technical-managerial solutions to improve the response in case of release of CBRN agents. In order to evaluate the quality of the proposals, a risk analysis will be carried out, both before and after the application of the suggestions.
