In this article the Layer of Protection Analysis (LOPA), as a technique for the risk evaluation relating to the hazardous industrial installations performance, is presented. The results of analyses are important in the terms of the safety management process in such installations. Based on obtained estimations the decisions might be undertaken which solutions to apply in order to mitigate the risk of hazardous installations performance to a tolerable level. The risk mitigation is provided by properly designed layers of protection, particularly the alarm system, treated as a part of protection layer. The alarm system should be designed and implemented with comprehensive consideration of the human factors. The role of the operator in hazardous installations is crucial mainly during abnormal and alarm situations in order to provide and/or recover system to normal or safety state. In the article some selected aspects of alarm systems designing process with special treating of human operator are outlined. Moreover, an example of the LOPA analysis for the accident sequence within a reaction container with consideration of human reliability analysis (HRA ) is carried out.
