In the previous report by the authors, the accidents in the Japanese shipbuilding industry were reviewed and it was concluded that the accidents of falling and tumbling from the higher place had occurred frequently, and then the causes and countermeasures for them were discussed using the virtual human model. In this paper, the same biomechanical analysis has been carried out against climbing up a ladder, passing an access opening, and walking on a scaffolding, because these are thought to have problems in the safety, and then the most suitable conditions in view of body burden have been studied using the response surface methodology; optimum climbing condition on the inclined ladder, the preferable position and size of the access opening, and the suitable walking posture on the scaffolding.
