Course Description

Layer of protection analysis (LOPA) is a popular risk analysis technique. It is conducted after a process hazards analysis has identified hazardous events needing further analysis to better understand the functional and risk reduction requirements for the safeguards. This course discusses the fundamentals of Layer of Protection Analysis, including the risk criteria, key work process elements, and methodology options. The course uses workshop examples to illustrate the methodology and emphasize key learning points.
