	Keyword : Lightning, risk, management, IEC62305
	A concept for risk management for lightning hazard has become profound, due to the growing demand for creating a robust social system to the occurrence of lightning discharge and lightning stroke. The research committee seeks to have a profound understanding of risk management for lightning hazard with investigating both domestic and international literatures. This report focuses on giving guiding principle of risk management in lightning hazard based on the surveillance. It is well known that the many institutes and organizations are working at from the prediction of lightning activity to lightning protection and lightning defense, and they achieve significant result in establishing the element technology. This report especially investigated the counter measurement technology form the view point of that the risk management for lightning hazard is to work the total system continuously. That is, the risk management guarantees no interruption of operation in total social system, due to lightning discharge and lightning stroke, even if there are some disavailability and destructive failures in social system including infrastructure. The committee precisely investigates the risk management standard in Europe and the united states, because they are ahead to Japan in risk management. In addition, the report also introduces the domestic risk management activities.
