Recorded Webinars: Modeling site specific safety and reliability – The Site Safety Index
As a result of several field failure studies, evidence is clear that failure rates for the same product vary from site to site. The ratio ranged from 1.2X to 2X based on data to date. Therefore we conclude that random failures can be divided in to two categories – product specific and site specific. The differences seem to be related to site training, site procedures and other variables that some have called “Safety Culture.” exida defines this variable as the “Safety Maturity Index.” This webinar will provide an overview of some of the field failure studies, present a simplified model to evaluate Site Safety Index (SSI), and describe the safety impact of SSI.
Blog Entry: Train Wrecks Waiting to Happen?
Hacking public transportation systems is always depicted on TV and movies. And they make it seem so easy… it only takes seconds for these fictional experts. Is it a reality? Well, the Amtrak train derailment that occurred earlier this year in Philadelphia got me thinking about “hacking” as a possible…
News Item: NEW exida WHITEPAPER: The Key Variables Needed for PFDavg Calculation
In performance based functional safety standards, safety function designs are verified using specified metrics. A key metric for process industry designs is called average Probability of Failure on Demand (PFDavg). After several studies of many field failure and proof test reports, several variables have been identified as key to a…

Blog Entry: Say What?
The “see something, say something” mantra is being used as a countermeasure for terrorism and crime, but it can also be effective to improve functional safety in development teams and plant sites. It could be useful in general process improvement as well. This can be especially evident during training sessions…

Blog Entry: What is SIL compliance?
The Safety Integrety Level (SIL) of a product is determined by three things: The Systematic Capability Rating The Architectural Constraints for the element The PFDavg Calculation for the product The Systematic Capability Rating Systematic Capability is established by having your quality management system audited per IEC 61508. If the QMS…
