In recent years, the increase in building heights has led to a rise in fatal accidents due to falls in the construction industry. When looking at fatal accidents by industry, the number of fatalities in construction remains the highest. Compared to all industries, the proportion of fall-related accidents in construction is high, and the causes of injuries and fatalities are largely attributed to temporary structures, buildings, and other constructions. When classifying the number of serious accidents by industry, construction accounts for the largest share. Thus, the development and dissemination of safety equipment surrounding the industry has become an urgent issue. We consider the development and dissemination of safety equipment for fall prevention to be our mission, and as one of those involved in this significant industry, we hope to contribute to society.
