This title presents a new and comprehensive prototype design and lifecycle model specific to human‑dependent barriers and safety critical tasks. Designed to supplement current practice, the model is fully underpinned by cognitive ergonomics and cognitive science. The book also presents a compelling case for why a new global consensus standard specific to human‑dependent barriers is needed. Taking a novel approach, it presents its suggested basis, framing, and content. Both solutions seek to redress deficiencies in global regulations, standards, and practice. The model is guided by industry recommendations and best practice guidance and solutions from globally recognized experts. Its processes are fully explained and supported by examples, analysis, and well‑researched background materials. Real‑life case studies from offshore oil and gas, chemical manufacturing, transmission pipelines, and product storage provide further insight into how overt and latent design errors contributed to barrier degradation and failure and the consequence of those errors. An essential and fascinating read for professionals, will appeal to those in the fields of human factors, process and technical safety, functional safety, display and safety system design, risk management, facility engineering, and facility operations and maintenance.
