Blog Entry: Industrial automation is in the cross hairs of the hacker
As the details of STUXNET’s design unfolded last fall, like many, I was truly impressed by the pin-point precision that the malware authors used to ensure that their target, and only their target, was impacted by the virus. In this regard, STUXNET may be one of the most responsible piece…
News Item: Slides Available for 61508 Certification for Mechanical Devices in Safety Applications Webinar
This webinar describes the certification process for simple mechanical products like valves, actuators, or solenoid valves. Topics that will be discussed include: • IEC 61508 requirements for these certification projects • The ability to get random failure rates for each failure mode, proof test coverage, and useful life via the…
Blog Entry: Keep Risk Personal
We are fortunate that Risk Analysts have developed a logical framework of quantitative and semi-quantitative analysis techniques that allow us to assess and optimally mediate risk. And we all know that this is part of the Safety Lifecycle, a series of engineering steps/procedures that represent best safety practices. These are…
News Item: exida Announces Safety Lifecycle Web Series
In recent years, both the IEC 61508 and IEC 61511 standards have been adopted and are rapidly gaining momentum. These standards address both equipment design and system implementation, and have broad implications on Safety Instrumented Systems (SIS). The safety lifecycle can be segmented into three phases: 1. Analysis 2. Design…
Blog Entry: When is a Variable Frequency Drive a SIS?
It used to be that a pump would operate at a single speed dictated by a motor, thus fixing the pump curve. As the discharge flow decreased due to a restriction downstream, the pump outlet pressure would increase reaching its deadhead pressure. If the downstream piping and vessels were designed…

Blog Entry: Buy Certified Equipment, Meet the Standard, Right? WRONG!
While correcting a CFSP exam, I read a question which went something like this: If you purchase all IEC 61508 certified equipment for a low demand safety instrumented function , then to meet the requirements of IEC 61511 : A. No other design verification is needed B. You must optimize…
