Safety structure by mechanical stop and consideration on stopping risk

Abstract

Consider accidents based on risk concept. As a prerequisite to the concept of risk, there is a premise that loss can be quantitatively evaluated, but in reality, such losses are not the only ones. Therefore, focusing on the loss that the user wishes to avoid, in particular, regarding the safety measures at the operation stage, the necessity of a safety structure due to the machine stop is clarified. Also, we consider losses due to machine stop as stopping risk and discuss them.
