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
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
Tracked E-Learning for Teams
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 main answer to the question is that the employer requires them to, usually to enable
Is 100% functional safety compliance possible?
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% compliance is NOT realistic when there are approximately 593 clauses, sub-clauses and bullet-point requirements
Safety instrumented systems and security standards
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).

10 steps to duty holder SIL conformance
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 Level (SIL) conformance?If your safety system installation pre-dates 2004 then you are highly unlikely to
Get a step-change in safety culture from hybrid training
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 both? An online plus classroom experience might just be the answer to getting a step-change
We don't need no education
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
How to assess IACS cyber vulnerability using a Security CHAZOP
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?There have been well

Why do control systems go wrong?
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
