A study for safety design of electrical machines considering human behavior

Manufacturers have to design machinery considering not only the intended use, but also a reasonably foreseeable misuse, which can lead to product-related accidents. However, manufacturers cannot predict everything the users might do for the machinery. In this study, we have focused on one type of misuse: when the users put their hands inside machinery. Safety mechanisms that deter users from putting their hands inside machinery are required to prevent such accidents. Therefore, in this study we have tried to understand what promotes this action. In this initial stage of our research, we experimented with the visibility and accessibility of an object, and evaluated whether there are related instructions that can affect human behavior.
