摘要：The article describes standard safety-protection layersaccording to EN 61511 standard. Their aim is to reducerisk, thus to decrease the frequency of occurrence ofthreatening incidents and/or consequences of such incidents.The aim of the article was to present currentlydeveloped means of increasing process safety, which arenot included in the standards. There are described: advisorydiagnostic systems, fault tolerant control systems,process simulators for operators training and IT systemssupporting safety. Such components can be treated asadditional layers of process protection. A simple examplecomparing the operation of alarm and diagnostic systemsas well as the example of the fault tolerant controlsystem of the level in the drum boiler in sugar factory aregiven.
