Safety barriers in the chemical process industries: A state-of-the-art review on their classification, assessment, and management

Barriers are used in various forms to assure the safety of chemical plants. A deep understanding literature related barriers is essential tackle challenges improving their design and management. This paper first provides an overview history development barrier concept. Subsequently, this elaborates a systematic review definition, classification, evaluation, performance assessment, management process industries. Based on review, study proposes practical classification benefiting identification indicators collection indicator-related data for barriers. The functions extended illustrated by involving resilience Performance assessment criteria proposed corresponding adaptability recoverability Finally, discussed. roadmap future studies develop integrated security ensure plants suggested.
