Analysing Safety Functions and Barriers

چکیده
The paper gives a summary of approaches to describing and modelling safety characteristics, including safety functions and barriers. In three examples, the safety function concept has been used to describe how actual safety systems worked. The examples are an incident investigation, a safety analysis of a part of a pharmaceutical plant, and safety rules in the railway industry. Advantages and disadvantages of the concept and approach are discussed.
