Babies, Bathwater, and Australian Safety Laws

The old saying goes, “Don’t throw the baby out with the bathwater.” But it looks like a number of people in Australia may be in danger of doing just that with their response to the country’s newly harmonized health and safety laws.

Getting Realistic Failure Rate Data - Part 1

Over the course of several blogs , I will talk about getting realistic failure rate data, where this failure data comes from, and how different methods of failure data analysis compare. I think if you understand this, you will begin to get a very good feel of what it…

It Ought to be a Crime

There is no shortage of drivers who try to “beat the red light,” or roll through a stop sign.  I see it every day (luckily BEFORE they hit my side door).  Even though everyone knows, or should know the “rules of the road,” there are some folks who are…

Lifecycle Analysis: It’s Worth the Effort

Obtaining My CFSE/CFSP Certification: Why Bother?

It’s an interesting question and one I asked myself.  For any engineer and/or professional working in the controls business or process industries where safety-related equipment is required, it is essential (per IEC61511-1 Clause 5.2.2: Organization and Resources) to prove competency to carry out any safety-lifecycle activities.  So what does…

Performing a Cybersecurity Risk Assessment as a Component of the PHA

There are three main components of the safety lifecycle: analysis, realization, and operation. We will be taking a look at the analysis phase, particularly related to the cyber industry.

To start, the first thing to do in both safety and security is do a detailed process, hazard and…

Imagine.  Marketing has just approached the engineering department and says your new safety product must have SIL 3 Capable certification instead of SIL 2 to be successful.  You are in the engineering group developing this new product.  Now what?

Let’s assume that the “change request” makes…

The Safety Lifecycle as a Risk Control Loop

I have been doing a number of recent projects introducing the safety lifecycle to companies that are new to the field. As a result I have been playing with various ways to think about the overall safety lifecycle philosophy. As many of the more experienced readers are…

Two Billion Hours

When I studied Reliability Engineering in graduate school, I was taught that failure rate data came from field failure studies.  I assumed that operating companies always kept accurate records when a piece of equipment failed.  I also assumed that someone would investigate the failures and assign a root cause.…
