Recorded Webinars: IEC 61508: SIL Certification Expectations
Due to the rapid growth of IEC 61508 Safety Integrity Level (SIL) Certification, many companies who haven’t achieved certification are now trying to catch up and understand what is involved. Manufacturers are now stuck with many questions and are searching for answers. How much time will it take? How much will it cost? How many man hours will be consumed to achieve certification? What are the benefits?
Questions like these and many more will be addressed in this webinar.
Blog Entry: New Version of ISA-18.2 Alarm Management Standard Is Released (2016)
The new and updated version of the ISA-18.2 standard (ANSI/ISA-18.2-2016, Management of Alarm Systems for the Process Industries) has now been officially released. This supersedes the original edition (2009). The new version incorporates feedback from 6+ years in the “field” and includes some updates based on the IEC 62682 international…

Recorded Webinars: CHAZOP Methods and Examples
Control Hazard and Operability Study (CHAZOP) is a procedure for carrying the safety and reliability analysis of existing or planned Control and Computer systems. The execution of a CHAZOP can take several forms depending on the focus and goal of the study. A CHAZOP can be performed to support the overall process hazard analysis or to determine the reliability of the control system, in addition it can be executed with several different techniques. The variety of choices can be managed by careful preparation and setting clear objectives. This webinar will provide a general overview of CHAZOP methodologies along with several examples that demonstrate the various approaches that can be taken.
White Paper: Comparing FMEDA Predicted Failure Rates to OREDA
Estimated Failure Rates for Sensor and Valve Assemblies Failure rates predicted by Failure Modes Effects and Diagnostic Analysis (FMEDA) are compared to failure rates estimated from the Offshore Reliability Data (OREDA) project for sensor and valve assemblies. Because the two methods of data analysis are fundamentally different in nature, it…
Blog Entry: Site Safety Index™ (SSI) – A Simple Model for Site Variations in Safety
In several of our technical papers over the years, we have noticed that failure rates for the manufacturer, model number are different at different sites, even when the processes were quite similar. When I have mentioned this to end users and manufacturers, often the response is “Yes, I have noticed.…

White Paper: 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 IndexTM (SSI) quantifies in part (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…
White Paper: Quantifying the Impacts of Human Factors on Functional Safety
It is not difficult to think of numerous ways in which human factors might impact functional safety. For example, imperfect repair, improper calibration, faulty installation, etc. can all contribute to decreases in functional safety performance. However, if actions are to be taken to mitigate these impacts then it is essential…
Recorded Webinars: How Can an Increase in Beta Decrease PFDavg?
Common cause susceptibility is the enemy of redundancy. Typically when adding redundancy, there is only limited benefit from a PFDavg perspective, simply due to accounting for common cause. Increasing the common cause factor tends to have a negative impact on PFDavg, at least in a standard 1oo2 configuration. In some cases increasing common cause will actually decrease the PFDavg, thereby arguably making a configuration safer by having a higher susceptibility to common cause. This is counter intuitive when only looking within the PFDavg context. This webinar will discuss common cause and review what the impact is on different voting architectures.

Recorded Webinars: Applications of 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 2X to 4X based on product type. 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 “Site Safety Index (SSI).” SSI is a simple way to include an impact from what many people call “systematic failures” in SIL verification. This webinar will provide an overview of the impact of SSI on random failure rates, realistic PFDavg calculations, describe the safety impact of SSI, and share an actual product example.
