Abstract
In Japan, natural disasters such as typhoons or earthquakes occur every year. This means that disaster relief works need to be carried out every year. There are certain specific risks that apply to relief works, such as the sudden collapse of existing building structures or the urgency of restoration tasks. It is therefore important to prepare all necessary safety measures beforehand. However, there has so far been little analysis of the work accidents that have occurred at past disaster relief works. This study addresses this with a quantitative investigation of construction work accidents that have occurred during past disaster relief works. It was found that falling accidents were the most prevalent type of accident in construction and civil works, and about 90% of fatal accidents at construction works were fall accidents.
