The purpose of a layer of protection analysis (LOPA) is to evaluate a single cause-consequence pair as a scenario. This method focuses on identifying and assessing specific risks associated with a particular event or hazard, allowing for a detailed examination of the effectiveness of existing protective layers in place to mitigate that risk. By concentrating on one cause and its potential consequences, LOPA helps fire protection and safety professionals make informed decisions regarding risk management and safety measures.

This single scenario approach is valuable because it simplifies the risk evaluation process, allowing for more precise analysis of the interaction between causes and their effects. It underscores the importance of layering various safety elements—like equipment, procedures, and personnel training—against the identified risk to ensure adequate protection for both personnel and property. Thus, LOPA is integral to creating a robust safety framework within firefighting and industrial applications, ensuring each identified scenario is thoroughly examined and managed.
