Recorded Webinars: Back To Basics – Getting to Know λ (Failure Rates)
Once again, we’ll go back to basics and run down everything you need to know to get started in functional safety. This webinar will focus on failure rates (λ)!
We will look at:
- What a failure rate is – λ
- How to find one
- What to do when you have one
- What’s a FIT?
- The different kinds (λS, λ SU, λ SD, λD, λDU, λDD)
- And finally, Why they matter
Blog Entry: Functional Safety Management Systems & Engineering Companies
In recent discussions with several engineering and integrators of Safety Instrumented Systems (SIS), it’s become very clear to me that the majority I have spoken to, don’t have any form of Functional Safety Management System 〈FSMS〉 in place. This is interesting because one of the changes in the 2016 edition…

Recorded Webinars: Cybersecurity Monitoring and Metrics - “You Can’t Manage What You Can’t Measure” Continuously?
Cybersecurity monitoring and metrics are keys to measuring cybersecurity performance, improving the ability to respond when incidents occur, and improving cybersecurity maturity. What metrics does your organization use to measure cybersecurity performance? Do you have monitoring in place today to identify security excursions? In this webinar we will break down how leading and lagging indicators can be used to improve cybersecurity monitoring as well as how improved continuous monitoring capabilities are becoming a critical part of the automation cybersecurity lifecycle. This non-vendor specific webinar will provide general guidelines and criteria that can be used for establishing an effective continuous monitoring capability for any system.
Blog Entry: OLD component data = Bad FMEDAs
When we first invented the FMEDA technique in the late 1980s the biggest problem was the component failure rate and failure mode data. Still is. I picked up a well-known standard for component failure rates and saw a date of 2010. The technology world has gone through an order of…

Blog Entry: Back to Basics: Failure Rates - λDD
The Greek symbol λDD is the detectable dangerous failure rate in functional safety expressed in the unit of measurement of FITs which can be determined through FMEDAs . ( FITs (λ) are failures per billion hours, expressed by 10 -9 hours). λDD is the number of dangerous detected failures per…
Recorded Webinars: What is Prior Use Justification?
The IEC61511 standard requires that designers of Safety Instrumented Systems (SIS) need to justify the selection of equipment to be used in Safety Instrumented Functions (SIFs). As such, the standard defines only two methods that are acceptable: IEC61508 certified devices or Prior Use Justification. Devices that are not certified to IEC61508 will require suitable justification for use in SIFs. The objective of Prior Use Justification is to gather evidence that the dangerous systematic faults have been reduced to a sufficiently low level, compared to the required safety integrity. This is in addition to the separate requirement to satisfy the random failure rate/probability criteria (i.e. PFDavg/PFH).
The purpose of this webinar is to shed some further light into the Prior Use Justification requirement for SIF equipment and what that means to the end user.
What you will learn?
- What is Prior Use Justification
- What that means to the end user
- How to justify use of the equipment
- What is the purpose of Prior Use
Who should attend?
- SIS designers and Engineering contractors
- Operations and maintenance personnel
- Plant Managers and Supervisors

Recorded Webinars: The Rise of Personnel Competency
As personnel competency grows, so does the competition. The question becomes, how do you keep yourself in the playing field that is right for you? Are you an expert? Are you someone that just wants to learn? Are you are in the middle? Choosing the personnel certification program that best suits your needs is very important and understanding the different programs is equally important. This webinar will briefly share with you many common questions that are asked each and every week about personnel certification. It will also discuss the different certification and certificate programs out there, share insight on those differences, and help paint a picture on which one(s) would benefit you.
