HADDON S UNWANTED ENERGY RELEASE AND HAZARDOUS ENVIRONMENT CONCEPT... 

There are two significant thought processes, one built on the other, of which knowledge is a requirement in professional safety practice. They are Haddon s unwanted energy release concept, extended by him to include exposures to hazardous environments, and the concepts on which MORT (management oversight and risk tree) was developed. 

All hazards are not addressed by the unwanted energy release concept. Examples are the potential for asphyxiation from entering a confined space filled with inert gas, or inhalation of asbestos fibers. But aU hazards are encompassed within a goal that is to avoid both unwanted energy releases and exposures to hazardous environments. Many authors have recognized the importance of Haddon s writings.
