(65i) Assessing Safety Culture Via the Site Safety Index

How can a company establish a baseline measurement of its safety culture against which to gauge improvement?  The Site Safety Index (SSI) quantifies (on a scale of 0 – 4) the degree to which a company’s end-user practices support the attainment and retention of an appropriate safety culture.  Further, the SSI can be used to appropriately adjust parameters that directly impact measures of safety such as probability of failure on demand.  Thus, the impacts of safety culture can be quantified.  This paper explains the way in which SSI is measured and illustrates how the measure can be used to assess impacts on typical safety parameters such as probability of failure on demand.
