Chapter 2 - Scope

Abstract

This chapter discusses the scope of the security and safety guidelines described in the book for the process industries. Security and safety guidelines should be considered for all of a company’s facilities, domestically and internationally, and they are applicable at both permanent and temporary facilities, whether located onshore or offshore. A typical security and safety review is usually intended to be a formal audit review of an essentially complete project design or modification to ensure that the probabilities or consequences of major incidents have been eliminated or reduced to acceptable levels prior to being placed in service. Risk analyses should be continually conducted as part of the project design to avoid the identification of major concerns by the later reviews. In fact, documentation from a design risk analysis should supplement the formal Hazard and Operability (HAZOP), Preliminary Hazard Analysis (PHA), What-If, or Security Vulnerability Analysis (SVA) reviews. During the period of initial implementation of process safety and security management policies, existing facilities may also be the subject of PHA, What-If, HAZOP, or SVA reviews. The basic approach for these reviews is quite flexible. They can be used to analyze a variety of operations and processes such as oil and gas well drilling, product manufacturing, chemical production, factory processes, chemical processing, transportation, marketing, computer control logic, operating procedures, organizational changes, security control, and monitoring.
