ABSTRACT
A key engineering tool for industrial practice is a management system appropriate for the risks being addressed (process safety, occupational safety, health, environment, asset integrity, etc.) [1]. Such safety management systems are recognized and accepted worldwide as best-practice methods for managing risk. They typically consist of 10 to 20 program elements that must be effectively carried out to manage risks in an acceptable way. This need is based on the understanding that once a risk is identied, it does not go away; there is always a possibility that the adverse event will occur unless the management system is actively monitoring company operations for concerns and taking proactive actions to correct potential problems [2].
