Most organizations have accident investigation procedures. However, these procedures are often based
on a blame culture and do not inspire the investigator to find and correct the defects in the management system (root caused) that allowed the hazards to exist and the accident to occur.

Several industries have adopted excellent accident investigation and analysis techniques. It is a basic function to locate and define the operational errors that allow accidents to occur. Competence in the application of modern accident/incident investigation tools will assist to learn and to prevent the recurrence of accidents and to evaluate the extent and location of management defects (root-causes), which contributed to the accident event.
