This video explains Dr. Reason’s Human Failure model that most industries, especially aviation and chemical processing, have been using my entire career. It does a very nice job explaining the types of human failures and their differences. Members can read my 2012 article “Causes of Human Failure” to get a more detailed explanation and to…...

Many safety management systems are initially developed in a theoretical environment or for ideal situations with implicit and explicit assumptions about the system’s optimal performance, equipment, and human activities. This is often called WORK-AS-IMAGINED and is formally documented in training, procedures, and equipment operating manuals. Differences between the designed performance or WORK-AS-IMAGINED and the realities…...

This information is intended to assist in assessing the human contribution to risk, commonly known as Human Reliability Assessment (HRA). There are two (2) distinct types of HRA: qualitative assessments that aim to identify potential human failures and optimise the factors that may influence human performance, and quantitative assessments which, in addition, aim to estimate…...

You will not stop all human error, but you can work on why those errors occurred and reduce the frequency, severity, and likelihood of humans to make similar mistakes.

I am not sure why I am so fascinated with the Human Factors aspect of process safety, but I blame my pals Bob and Steve at Unwin Company for beating it into my head during the first PHA I did with them way back in 1999. They ripped me apart with how our procedures were…...
