The identification and choice of a suitable risk assessment model has been considered as a crucial issue for decades. In fact, the concern for safety in industrial activities, both inside the establishments and in the surroundings, has a long history. As a result, many laws and regulations apply. The use of risk assessment techniques is fairly widespread in policy and regulations.
