Hazard and Operability Study (HazOp)

HazOp is a systematic technique for reviewing a process design to understand the hazards present and identify appropriate control measures.

Layer of Protection Analysis (LOPA)

Layer of Protection Analysis (LOPA) is a semi-quantitative method of risk assessment. It is used to analyse “high severity” scenarios identified during HazOp in more detail. (These are usually the events that could potentially cause a fatality or another incident of equivalent severity.)

LOPA is often used for “SIL Determination”, where a SIS Safety Instrumented System is required. In other words, LOPA is used to decide the reliability (SIL Safety Intergrity Level ) required from the SIF Safety Instrumented Function . Read more about LOPA.


Because Hazard & Risk Assessment is one of the lifecycle phases of the functional safety standard IEC 61511, the H&RA must be “verified” as part of compliance with the standard. The purpose of verification is to check that the work has been done correctly.

Functional Safety Assessment

All work done to deliver the lifecycle phases should be “assessed”. The purpose of Functional Safety Assessment is to check that suitably competent people were selected to carry out the work, and that it has been done in accordance with the relevant procedures and plans.
