Training in Process Safeguarding (Safety in Process Design) covers a wide range of subjects with many applications in hydrocarbons and chemical processing. As the name suggests, it addresses the process engineering and safeguarding aspects of processing equipment/units. The process design safety orientation of the participant results in safe process designs.
