People create environments such as cities, roads, vehicles, buildings, and machines that originally carry out human social activities. The design can be improved, and the environment can be improved so that disasters are less likely to occur. To ensure safety in a social environment, it is necessary to study, rethink and improve the disasters that occur in that environment. Once a disaster has occurred, we will thoroughly investigate the cause of the disaster and find a way to prevent the disaster from occurring. By investigating and clarifying the cause, you can find a way to protect yourself from disasters and reduce the damage. The important point is the attitude of constantly thinking and improving to ensure safety. We need to continue to share the wisdom of safety throughout society. In order to further improve safety, it is necessary to acquire the ability to anticipate the worst in various cases and find out the worst disaster cause. If you can predict the occurrence of a disaster and acquire the ability to prevent it, you can reduce the number of disasters. We will ensure the safety of society by continuing to carry out these three steps repeatedly.
