This new book describes the application of major safety reviews used in the process industries and how they can be adapted for security vulnerability analyses. It is the second edition of a best-selling title published originally under the Noyes imprint (0-8155-1353-4) that was entitled “Applications of HAZOP and What-If Safety Reviews to the Petroleum, Petrochemical and Chemical Industries.” The author, Dennis Nolan, is well known in the process industries for his wealth of knowledge of fire protection engineering, risk engineering, loss prevention engineering, and system safety engineering.
