Recorded Webinars: Validation of Given Failure Rate Data for Process Industry Applications
A given Safety Instrumented Function (SIF) design must be verified to meet the required SIL level by checking systematic capability, architecture constraints and probability of failure on demand. Two of these checks require the failure rate data for each device. Fortunately, many device manufacturers are getting their products certified per IEC 61508 and many of the certificates now have failure rate data. Others supply analysis reports with failure rate data. All such data must be checked to make certain it is applicable for the process industries as some data has been derived based on machine safety or automotive applications.
This webinar will show some examples of manufacturer provided failure rate data and a methodology created to validate device type failure rate data for the process industries.

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.
