Workplace accidents, according to accidents at work statistics, not only cause tremendous economic loss but also lead to severe physical injury and even fatality. Take Taiwan for example. Each year, a lot of deaths are found to result from being dragged or being entangled in workplaces. A large part of them are related to operation of machinery or contact with equipment. With a view to enhancing safety protection in operation of machinery or contact with equipment, the present study referred to the five senses of Kansei engineering, including visual, auditory, olfactory, taste, and tactile ones, to analyze the emotional feelings of on-site workers. This study aimed to understand the alarm signals related to hazards in workplaces. Data based on questionnaire survey for comparison and analysis was first implemented to understand what constituted an ideal safety protection design. Next, the relational analysis of the five senses in the prevention of occupational accidents was conducted through traditional statistical procedure and regression analysis. Finally, this research proposed, on the basis of on-site workers' emotional feelings and job experience, how to unite mechanical characteristics and the protective mechanism of automotive control to lower the rate of being dragged and being entangled in workplaces, thus achieving workplace safety.
