“…When successful, disaster-risk management efforts aim to reduce the effects of hazards, through activities and measures related to prevention, mitigation, and preparedness [10]. According to Kátai-Urbán [11] the execution of the protection tasks against major accidents is basically divided into three periods: the period of prevention and preparation, the period of defence (emergency management) and the period of restoration with the elimination of the consequences Response: response is addressing all the actions to be taken once an accident has occurred or there is an imminent threat of an accident, including mitigating adverse effects on health, the environment and property. Examples include the informing of the public and authorities concerned, dispatching emergency services, conducting detailed analysis and assessments of environmental and health impacts, and coordinating incoming assistance [12].…”
