Establishing a database on potential accidents

A Coarse analysis results in information on hazards and potential accidents similar to that obtained though accident investigations. In many cases it may be practical to store the results in a computer for easy retrieval and summarisation. This approach offers several advantages  

Example An aluminium company conducted a Coarse analysis of its primary aluminium plants. An analysis team was established for each department that participated in the analysis. The teams were lead by SHE experts from the corporate staff. In addition the teams included the department supervisor and operations and maintenance personnel. 

The teams identified in all about 800 different potential accidents. A database was established that contained the following information about each event  

Type of event (compare Table 22.2). Estimated frequency, consequence and risk. 

The identified accident risks were grouped and the groups were ranked by accumulated risk level as a basis for prioritising further follow-up. For the electrolysis departments, the following types of events were considered to be of special concern
