Safety is one of the most important points in engineering ethics. Although safety, economic efficiency and convenience contradict each other, these three criteria must be balanced in any product or service. When we balance safety with economy or convenience, we must consider diversity of value for safety because safety means that risk is in acceptable range and the range depends on the person. To contribute safety of society and to cultivate consideration for users, lectures for engineering ethics should contain elements of safety engineering, such as risk assessment, intrinsic safety, hazards and dangerous state.
