LOPA stands for Layer of Protection Analysis

Do you know the tolerable frequency for your company?

Identify a single consequence to analyze

Identify independent protection layers and assign a risk reduction factor

Calculate the expected frequency of the consequence scenario

Decide if risk is acceptable based on the tolerable frequency

Now the risk is acceptable

Adding a safety instrumented function is one option to meet the tolerable frequency.
