The March 2026 issue features a cover story on process hazard analyses. Layers of protection analysis (LOPA) is a simplified quantitative analysis tool frequently used alongside hazard and operability (HAZOP) studies to help assess the residual risks of high-consequence scenarios. This article compares the LOPA gaps between different analysis methodologies using multiple basic process control system (BPCS) failures as potential initiating causes.

Applicability of LOPA Summation in Complex Process Scenarios
For complex processes, summing up the predicted frequency of protection layer failures can yield inaccurate and overly conservative failure rate estimates. To truly quantify the likelihood of a process incident, more nuanced analysis is necessary. Read this open access article now!
