What level of risk does the LOPA process aim to achieve by implementing protection layers?

The LOPA process aims to achieve a reduced level of risk by implementing various protection layers. This approach involves identifying potential hazards and assessing their associated risks to determine whether the existing protective measures are sufficient or if additional layers of protection are necessary. Each layer is designed to mitigate risk by providing independent safeguards against identified hazards, thereby lowering the overall risk to an acceptable level.

The main objective of LOPA is to ensure that residual risk remains within tolerable limits, enhancing the safety of operations in an organization. By systematically analyzing potential failure scenarios and effectively deploying protective measures, LOPA facilitates the reduction of risk through a structured methodology, allowing organizations to maintain a safer working environment.
