In either format, potential hazards that pose high risk are identified, as are their cause and major effects. In addition, for each hazard identified, a preliminary means of control is prescribed. The analysis usually begins at the point of input and follows according to process flow. The technique has some disadvantages. To carry out this study, a multidisciplinary team follows a structure that includes a series of guidewords.
Results depend on the quality of process information available and the experience of team members.
Define the study's scope and purpose. This includes specific process areas to be studied, as well as type of hazard consequences to be considered. The objective is included within the purpose. Select a team to perform the study. Ideally, this team should include five to seven members from different areas within the operation.
