What is LOPA?
Layer of Protection Analysis (LOPA) is a methodology for hazard evaluation and risk assessment.
It helps the analyst make consistent decisions on the adequacy of the existing or proposed layers of protection against an accident scenario.
This decision-making process is ideally suited for coupling with a company's risk-decision criteria, such as those displayed in a risk matrix.
LOPA is a recognized technique for selecting the appropriate safety integrity level (SIL) of your safety instrumented system (SIS)
per the requirements of standards such as ANSI/ISA-84.00.01, IEC 61508 and IEC 61511.
