The accident at Chernobyl occurred in April 1986 at the Chernobyl Nuclear Power Plant in Soviet Union. The incident occurred during a scheduled safety test. A combination of inherent reactor design flaws and operators’ mistakes resulted in reactor’s No.4 disaster and the emission of a large quantity of radiation. The immediate actions involved the fire extinguishing, the cleanup of radioactive residues and the prevention of a new explosion. For this purpose, plenty of people worked with self-sacrifice. The people who lived nearby were removed. As far as the socio-economic impact for the Soviet Union is concerned, it was quite serious. Moreover, the environmental and human health consequences were also alarming with thyroid cancer being the most studied. Useful conclusions, especially for the safety both of reactors and nuclear power, as well as for the impact of radiation at ecosystems have been drawn. The debate about the use of nuclear power has remained open ever since.
Mass shootings incidents occur with increasing frequency over time. Studying these cases proved that, despite their diversity, several common features could be taken into account in the early detection and possible prevention of certain future cases. Accepting that such incidents may occur anywhere and anytime, societies need to be prepared for their more effective response. Informing citizens about the best way to react to a mass shooting event is considered crucial and essential. The "Run-Hide-Fight" guideline/directive seems to be the most appropriate guideline given to the public. Proper training, of both the Suppression Forces and the emergency medical care providers, is considered of utmost importance. The role of the Incident Commander, regarding the incident management, as well as the external bleeding control of the injured people, are factors of paramount importance in trying to mitigate the casualties from such an incident. The alertness of both citizens and organizations/structures may lead to early detection of potential perpetrators and thereby averting a mass shooting incident. To achieve increased survival and a reduced number of casualties from a mass shooting event it is vital proper education be present at all levels. The response to a mass shooting event should be imprinted in an Emergency plan. Such a plan should have been decided and made, by the Security and Suppression Forces, the Healthcare Institutions, and the Public Safety Answering Point.
