    This unique manual is a comprehensive, easy-to-read overview of hazards analysis as it applies to the process and allied industries.

It addresses the different types of structured analytical techniques for conducting Process Hazards Analyses (PHA), provides a "What If" checklist, and shows how to organize and set up PHA sessions. Other topics include layout and siting considerations, Failure Modes and Effect Analysis (FMEA), human factors, loss of containment, and PHA team leadership issues.
