Safety (from Latin “sine cura“: without worrying) can be defined as “the knowledge that the evolution of a system will not produce unwanted circumstances”. In simpler terms: knowing that what we are going to do will not cause damages. The total safety is available only when there is no danger. In absolute terms, it is a concept hard to report in real life, even if the application of the safety rules makes harder the occurrence of harmful events or accidents, improving instead the quality of life. (Wikipedia, def. “safety”).
