Layer of Protection Analysis is often the tool of choice in the chemical process industries for additional evaluation of risk, and consideration of mitigation options. Due to its simple, meaningful visual representation of risk, Bowtie analysis is already widely used in Europe and is gaining in popularity in the US. Bowties and other barrier methods consider the preventative and mitigative barriers in a hazardous chain of events. Case studies and examples of innovation in these techniques and applications of them to real-world problems are desired.
