Layer of Protection Analysis (LOPA)

Layer of Protection Analysis (LOPA) is a semiquantitative tool typically used after completion of a well-documented process hazard analysis (PHA) or any other qualitative hazard evaluation for analyzing and assessing risk. It often uses order of magnitude categories for initiating event frequencies, consequence severity and the likelihood of failure of independent protection layers (IPL) to estimate a specific scenario’s risk.

How Layer of Protection Analysis Helps Chemical Process Industries

Conducting a LOPA study is essential to maintain the utmost safety in your facility. Here are some things it can help with:

Layer of Protection Analysis (LOPA)

With a set of rules from the Center for Chemical Process Safety (CCPS) and company standards, LOPA can be a consistent, reproducible method of evaluating the risk of scenarios, and that’s why its use has been gaining traction in the chemical industry.

In addition to its popularity in the industry, LOPA, also known as Safeguard Protection Analysis (SPA), is required by Cal/OSHA GISO 5189.1 and CalARP 19 CCR 2762.2.1, which states that for each scenario from the PHA that can result in a major incident, the company must complete a written SPA which determines the effectiveness of existing, recommended and alternative safeguards from the analysis.
