#1304 - Layer of Protection Analysis (LOPA)

Course Objective

Upon completion of this course, participants will be able to apply the new and powerful LOPA cost-effective risk assessment technique. LOPA is a semi-quantitative tool that uses rigorous rules to analyze scenarios and assess the associated risk. Various risk tolerance criteria are presented and discussed together with numerous worked examples to demonstrate the technique. Additional uses for LOPA (including identification of safety critical equipment, risk-based maintenance and training, etc.) are also discussed.

Who Should Attend

Individuals who are responsible for managing corporate process safety/risk assessment functions and who wish to assess the potential advantages offered by LOPA. Also, individuals who are performing process hazard evaluations or risk assessments.

Please note that participants should already have a basic understanding of process hazard evaluation techniques (See Course No. 1303).
