Become a certified functional safety professional – CFSP or CFSE

Competence is a critical part of functional safety management for conformance with IEC 61511 and IEC 61508 - by eFunctionalSafety

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 which explains some of the background, what your options are, and how much preparation time you’ll need to put in.CFSE historyThe Certified Functional Safety Expert (CFSE) program was set up originally […]

Safety life-cycle accountability with an RACI matrix

What happens when a 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 issue of accountability is a clear differentiator. When it goes wrong, people, the environment and finances can get hurt.Read to the […]

Does using a Safety PLC mean IEC 61511 compliance?

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 you decide whether a programmable system is advisable or necessary given the possibility for cyber attack* in the internet-of-things era?*Watch […]

We don’t need no education

Competence is a critical part of functional safety management for conformance with IEC 61511 and IEC 61508 - by eFunctionalSafety

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 my purposes hopefully it will get attention. * The lyric “We don’t need no education” is extracted from Pink Floyd’s “Another […]

How to assess IACS cyber vulnerability using a Security CHAZOP

iacs and sis cybersecurity by eFunctionalSafety

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 assessment be approached*, and what can you do to prepare for it?*Watch a webinar recording about cyber-security here.There have been well […]

Killer tools for improving safety and reducing project cost

Operation and maintenance procedures for Safety Instrumented Systems (SIS) will vary from company to company. However, there are some specific requirements that need to be covered for safe continued operation. The first blog on this topic discussed general operation and maintenance (O&M) requirements for sustaining the integrity of a SIS. This second article discusses the requirements […]

Process SIS standards are changing – learn more

The process sector standard IEC 61511 is aimed at applications where instrumented systems are used for risk reduction in the process industry sector – including applications in chemicals, oil and gas, pulp and paper, pharmaceutical manufacturing, food and beverage, and non-nuclear power generation. Reduction of risk can be applied in the context of people, the […]

5 reasons you should assess functional safety during operation

Safety Instrumented Systems Design - background process industry image - eFunctionalSafety

Hazardous process industry sites must carry out periodic functional safety assessment (FSA) of safety instrumented systems. But why? Many hazardous process industry sites have viewed Functional Safety Assessment (FSA) as a project activity to be completed when a new safety instrumented system (SIS) gets installed, and of course, that is absolutely correct. Some have also registered […]

No such thing as a free lunch?

eFunctionalSafety online e-Learning

My Father used to say this a lot. “There’s no such thing as a free lunch”. I never got the meaning as a child…all my lunches seemed to be free? Sadly, he passed away when I was in my teens, so I guess I never really understood the real meaning until later on in life.  […]

Costly competence

Competence is a critical part of functional safety management for conformance with IEC 61511 and IEC 61508 - by eFunctionalSafety

The headline poses a tricky question. Process accident history is awash with many examples of apparent incompetence involving safety instrumented systems (and other protection layers), some of them resulting in literally billions of dollars of losses, not to mention large environmental impact and loss of human life.So, developing and maintaining competence in the area of […]

IChemE independently assessed the Safety Instrumented Systems (SIS) Foundation Online Training course and materials benchmarked against their internationally recognised professional standards.The course is now part of an exclusive range of training programmes endorsed by IChemE to support the professional development of chemical, process and biochemical engineers.

Why do control systems go wrong?

Safety life-cycle- adapted by eFunctionalSafety from IEC 61511

The safety life-cycle, sometimes spelled lifecycle, was conceived after the Health and Safety Executive (HSE – a UK government agency) found that accidents involving control systems could be attributed to various different root causes.The highest root cause of accidents was found to be poor specification of the system (44% of cases), followed by modification after […]
