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.

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.

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 publicized examples of cyber-security breaches

Key safety instrumented system operations advice

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

5 reasons you should assess functional safety during operation

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?

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.

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 cases), followed by modification after
