Integrated Safety and Security Management to Tackle Domino Effects

Abstract

Domino effects may be induced by both intentional and unintentional threats. To deal with possible intentional and unintentional domino effects, this chapter develops an integrated safety and security management framework. First, safety and security management principles are introduced to show the similarities and differences between safety management and security management. Then an integrated safety and security management framework is proposed based on risk assessment and management principles. In this framework, safety measures and security measures are integrated and divided into three categories: detection measures, delay measures, and emergency response actions. This framework mainly consists of six parts: chemical plant description, threat and hazard identification, the vulnerability of installations subject to hazards and threats, the vulnerability of installations exposed to domino effects, consequence analysis, risk treatment, and risk reduction. According to the framework, protection strategies encompassing both safety and security can be formulated to obtain an acceptable domino effect risk.
