ABSTRACT
The desire to be free of accidents and injuries has been a part of mankind since the beginning of time, with one of the earliest written references to safety from the Code of Hammurabi c.1750 BC, stating that the builder of a house would be put to death if poor construction caused death of the owner. System safety engineering and risk assessment has changed much since then; however, many still confuse the terms, and frequently use them interchangeably.
