INDEX safety risks associated

Tools are available to assist in comparing the risk associated with two or more different processes. For example, the first sheet of the Dow Fire and Explosion Index (FEI) (Dow, 1994b) ranks the safety characteristics of the process from a fire/explosion standpoint, without taking credit for protective and mitigation features. The Dow Chemical Exposure Index (CEI) (Dow, 1994a) and Id s Mond Index (ICI, 1985 Tyler, 1985) are other ranking tools. 

Clinical trials aimed at securing registration and approval for a new treatment are often biased toward assessing the safety of the treatment we need, however, to bear in mind that risks are associated with the disease as well as with the treatment, and that a more clinically relevant index than treatment toxicity is the disease risk-treatment risk ratio. 

There exists no universal method for the assessment of fire and explosion risks which would be accepted as obligatory in the standard regulation in the field of fire and explosion safety of industrial buildings and associated facilities indoor. At the same time these regulations allow the application of qualitative and quantitative approaches, including index methods and the full probabilistic approach.
