Several safety analysis method have been developed already. Some of them are internationally known and proved, some have been used and developed more or less inside companies. Information requirements of the methods are different, also the result prodused vary. Thus different safety methods are suitable for different stages of process development, design and operation some safety analysis methods are discussed below in more detail. In conceptual design, process routes can be compared and ranked by using inherent safety indices. In this paper, some inherent safety index methods presented in literature are compared and their properties and limitations discussed.
