Hazop and hazan were developed to identify and assess hazards in the process industries. The use of these techniques leads to safer plants, the elimination of many operational problems at the design stage and improvement in reliability. Understanding the practical issues involved in the correct implementation of these techniques is the theme of this book. It provides the basics of applying hazard and operability study (Hazop) and hazard analysis (Hazan).
