Prevent loss and improve safety instrumented systems - SIS.
Calculations for verifying a Safety Instrumented Function (SIF) with Safety Integrity Level (SIL) performance requirement are standard in the process industry these days. You will find examples in both the IEC 61508 and IEC 61511 Read More
When it comes to implementing safety instrumented systems (SIS) to comply with functional safety standard IEC 61511, the safety PLC is a pivotal device to specify. So, what are the key questions that you need to Read More
Suppose your staff and contractors need to get up to speed with improving IEC 61511 functional safety competence for safety instrumented systems. If that's the case, this is the right blog for you.Developed over the Read More
You may not know or care much about Hardware Fault Tolerance (HFT) unless you're working in a hazardous industry with Safety Integrity Level *SIL requirements. However, just like the multiple safety systems in your motor Read More
A SIF gets specified as an automated independent protection layer (IPL), often as the result of a safety integrity level (SIL) target-setting exercise, also known variously as a SIL determination, SIL study or SIL assessment.Like Read More
Are the terms "Mean Time Between Failures" (MTBF) and "Safety Integrity Level" (SIL) related to each other? Some would think not but read on if you'd like to discover if that's true.MTBFEquipment suppliers have been Read More
Ever wondered how to proof test a safety instrumented system? Proof test is a term that was first coined in the original IEC 61511 standard (functional safety - safety instrumented systems for the process industry Read More
This blog will help if you have ever tried to do a SIL calculation (Safety Integrity Level) for probability of failure of a safety function. A procedure, often known as SIL verification, is used to Read More
This article proposes real benefits for team online eLearning for the topic of IEC 61511 functional safety competence with safety instrumented systems.IEC 61511 Functional SafetyMany think of IEC 61511 as a design standard. Yet, it Read More
The safety instrumented system PDF was written to provide an overview of key terminology and aspects of the safety life-cycle according to IEC 61511 edition 2. The eBook is aimed at process industry functional safety Read More
If you own or operate any electrical / electronic or programmable system that has safety functions with a SIL (safety integrity level) rating, then you need to conduct periodic functional safety audit or FSA 4.I Read More
I often get asked how to become a certified functional safety professional or certified functional safety expert (CFSP or CFSE). Well, here's a blog that explains the background, what your options are, and how much Read More
BUYER BEWARE! There are many types of course currently marketed as "ONLINE", that sadly do not make meet the simplest test of what this actually suggests. I have followed this carefully over the past 10 Read More
Functional Safety Assessment may be a dry topic even at the best of times, so much so that I took it as a personal challenge to try and write a paper about it!The paper highlights Read More
What happens when a functional safety project is not well planned, plans are not properly communicated or accountabilities are unclear? Safety-related projects are essentially no different to any other project in terms of management, but the Read More
When it comes to deciding on using hard-wired logic or a Programmable Logic Controller (PLC) for a safety instrumented system logic solver design, there are some clear positive and negatives to each approach. So, how do Read More
Why do people attend training courses, and what can online Cloud based E-Learning provide for your competence management system that a traditional classroom course cannot?Why does any employee attend a training course? Very often the Read More
Achieving complete compliance with "risk-based" functional safety standards like IEC 61511 is a great objective to have, but is it, in fact, possible? Experience with process industry functional safety assessment and audit would suggest that 100% Read More
If you're responsible for a Safety Instrumented System (SIS) with Safety Integrity Level (SIL) rated functions, then you might be wondering where to start with cybersecurity standards for industrial automation and control systems (IACS). Read Read More
Perhaps you have installed safety systems which date from the 1990's or early turn of this century. If so, you might be wondering whether you need to follow IEC 61511 edition 2 for Safety Integrity Read More
How do you get valued staff and contractors to engage with Process Safety, Functional Safety and similar "tricky" subjects? Send them on a training course or ask them to take some online training? How about Read More
The headline, extracted from a popular song lyric*, uses the double-negative "don't need no", quite intentionally - to help emphasize a point. Whatever the song writer meant I'll leave to others to decipher, but for Read More
The recently updated process sector safety instrumented system (SIS) standard IEC 61511 now requires that a "security risk assessment is carried out to identify security vulnerabilities of the SIS" [1]. But how should such an Read More
