The Necessity of Integrating Safety and Security Barriers in the Chemical Process Industries and its Potential Framework

Safety and security barriers are implemented in various forms to protect chemical plants from undesired accidents and mitigate the disastrous consequences. However, the necessity and rationality of integrating safety and security barriers need to be investigated, and the difficulty in integrated management of safety and security barriers is still a challenge. In this study, the research status of integrated safety and security barrier management are reviewed before the necessity, and theoretical ground for integrating security and safety barriers are elaborated. Then, a unified classification of safety and security barriers is proposed to benefit the collection of performance indicator-related data and further support the performance assessment of safety and security barriers. Finally, a framework for integrated management of safety and security barriers is suggested to support the integrated management of safety and security barriers.
