Accident prevention requires the creation and maintenance of a safe working environment and the promotion of safe behavior. Accident prevention began as a reactive process. This was based largely on waiting for accidents or health problems to happen and then devising and implementing some form of control to prevent these types of accident or health hazards from re-occurring in the future. As a result, such controls that are found in industry have been strongly reactive in their nature. The Module covers issues related to the nature of accidents, accidents factors, prevention and registration.
