This study estimates the demands for safety training courses with reference to research on safety training records, seafarer statistics, target groups for safety training, expiry dates of existing safety courses, seafarer employment rates, the retirement age, etc. These results are compared with the seating capacity of the maritime training institute to analyze the anticipated increase in and convergence of demand can be accommodated. The average annual safety training needs for the next five years according to the Seafarers Act include approximately 10,444 people, and the proper annual seating capacity of the maritime training institute is approximately 7,280 people at present. Thus, in order to respond to an increasing demand for safety training, it is necessary to expand the capacity of the safety training facility.

The demand of gas as an eco-friendly energy source has being increased. With the demand of gas, the use of gas is also increased, so injury and loss of life by the explosion and fire have been increasing every year. Hence the influence on over-pressure caused by Vapor Cloud Explosion in enclosure of experimental booth was calculated by using the Hopkinson's scaling law and damage effect by the accident to a human body was estimated by applying the probit model. As a result of the damage estimation conducted by using the probit model, both the damage possibility of explosion overpressure to human over 3 meters away and that of overpressure to tympanum rupture over 25 meters away from the explosion shows nothing.
