Risk measures in practical use: risk reduction has its price, but is it known?

Different risk measures are discussed in order to decide which to use to best express the risk workers are exposed to. A new risk measure is introduced and advantages and disadvantages are presented. The need for a new risk measure (Expected Number of Fatalities Rate ENFR), is discussed and explained with the help of an example. The example also contains a comparison with the well-known FAR-value. Also some problems and benefits of introducing a measure of the kind: ΔRISKΔ$ are discussed and conclusions made. The question of what amount of money should be used on risk reducing activities is also addressed.
