Abstract

Safety analysis has been applied to different kinds of automatic equipment, ranging from relay-controlled to computerized equipment. The safety analyses were mainly systems oriented. This implies a concentration on system functions, with consideration of technical, individual, and organizational factors. Two relatively broad methods were used, energy and deviation analysis. More detailed methods of analysis were normally not applicable for a number of reasons, such as low safety levels of the systems studied or insufficient information.The purpose of the analyses was to propose measures for improving safety. The general approach was a combination of safety analysis and the application of design principles centred on safety. In all cases the control systems were important for safety, and extensive lists could be made proposing safety improvement measures. One of the more important areas was the planning and facilitation of the operators' tasks when correcting deviations of different kinds.
