A look at safety culture, how it effects SIFs and the Site Safety Index!
Numerous field failure studies have shown that the failure rate for a specific device (same Manufacturer and Model number) will vary from site to site. Research has concluded that random failures can be divided in to two categories: product specific and site specific. The difference in failure rates could be any range from 1.2X – 2X based on data received to date. The Site Safety Index (SSI) was created to account for these failure rates differences as well as other variables. exida has written the Site Safety Index (SSI) information in the FMEDA reports, to provide an overview of the Site Safety Index (SSI) model used by exida to compensate for site variables including device failure rates.
This webinar will provide an overview of the impact of SSI on random failure rates, realistic PFDAVG calculations, and the impact of a good safety culture on lifecycle cost, along with reviewing the changes in the exida FMEDA report which captures this information.
