ABSTRACT
Technical facilities safety is fundamental issue for human society and its development. It is reality that it is broken by many known and newly cognized risks that are related to forever grooving complexity of technical facilities and whole world. Today, we know that it is also necessary to consider the risks that are connected with interfaces among their subsystems and components. With regard to the world dynamic development, it is necessary to monitor the priority risks and to cope with them during the time. The measure of safety level is performed by help of logically arrangement of requirements of individual techniques used at work with risks in technical facilities, fragmented to 7 domains and Maximum Utility Theory principle. The paper also shows the results on safety levels for 5 technical facilities.
