Method for investigating management impact to causes and consequences of specific hazards, MIMIX

Method for Investigating Management Impact to Causes and Consequences of Specific Hazards (MIMIX) is a new method for the identification of deficiencies in managerial means and practices used for maintaining and improving safety in a plant. MIMIX is a part of TOMHID methodology which is aimed for overall identification of hazards in a chemical plant. However, MIMIX can be used independently. This report includes guidelines for carrying out a MIMIX analysis. Some experiences from TOMHID analysis case studies, forms and other supporting material (appendix A) and an example of the preparation of incident scenarios (appendix B) are also included in the report. MIMIX consists of three main stages: preparation of incident scenarios, worker interviews and management interviews. A couple of incident scenarios are prepared to support the worker interviews. In each worker interview, such undesired conditions in the plant which promote errors and violations affecting the incident described in a scenario are identified. Deficiencies in managerial means and practices used for correcting the identified undesired conditions are investigated with management interviews.
