The LOPA study provides a more consistent approach to Safety Integrity Level (SIL) Assessment. Independent Protection Layers are identified, that may provide risk reduction and can accurately define the performance requirements of the Safety Instrumented Function.
LOPA is a quantitative risk assessment process providing a Target Probability of Failure on Demand (PFD), which is associated with the Integrity Level requirements (SIL) as per IEC 61511.
This activity is referred to as SIL Determination or SIL Assessment because the performance requirements of a safety function is expressed as a Safety Integrity Level (SIL) as per the requirements of IEC 61508 / IEC 61511.
