Abstract
Treatment of dependencies in safety analysis is discussed. Important failure causes and coupling mechanisms harming redundant system solutions are presented. Defences to minimize dependent failures are identified and discussed. Control of dependencies by knowledge, good routines, information systems and safety culture is identified as the key factor in avoiding the occurrence of simultaneous unavailability of redundant equipment.
