A 90-minute lecture was given to 213 selected students from all grades on May 7, 2025. In Part 1, the lecture was structured to answer the questions, “Why do accidents occur? Why do the same accidents occur repeatedly over time?” and “How can accidents be prevented?” Explosion accidents at universities in the United States, avalanche accidents in Hokkaido, and an aircraft collision accident on Runway C at Tokyo International Airport were used as real cases to explain the mechanisms of accident occurrence, accident prevention methods, defenses in depth, and the necessity of scientific accident investigations.
In Part 2, accidents such as those during swimming, SUP, fishing, and snorkeling, as well as organizational accidents such as diving accidents, mountain accidents, and accidents at sea and rivers that occurred at universities, were analyzed using the RMQMP model, and accident contributing factors and accident prevention methods were explained.
