When we were children, adults frequently told us to stop and think—good advice, but they rarely told us what to think about. I have sought to overcome this omission with the ‘three-bucket’ model described below. This model forms the basis of the mental skills designed to impart error wisdom and risk awareness. The buckets correspond […]
The probability that the total system will perform correctly when it is available is the probability that the hardware/ software will perform correctly, times the probability that the operating environment will not degrade the system operation, and times the probability that the user will perform correctly. By defining the total system this way, human performance
One of the best examples of Human Factors Engineering is seen daily when driving… street signs. We all know a STOP sign when we see one. It may be the most recognized sign in all advanced societies. Did you know that at least 35 countries use a red octagon as their stop sign? But imagine
The skill-based performance involves highly practiced, primarily physical actions in very familiar situations in which there is little conscious monitoring. Such actions are usually executed from memory without significant conscious thought or attention. Behavior is governed by preprogrammed instructions developed by either training or experience and is less dependent upon external conditions. Information that can
Human nature encompasses all the physical, biological, social, mental, and emotional characteristics that define human tendencies, abilities, and limitations. One of the innate characteristics of human nature is imprecision. Unlike a precise machine—each time, every time—people are imprecise, especially in certain situations. For instance, humans tend to perform poorly under high stress and time pressure.
Here are the five principles of Human and Organizational Performance (HOP) explained: People make mistakes Blame fixes nothing Context drives behavior Learning is vital Response matters
I think most SAFTENG members will be able to pick up on several keywords and phrases and understand the significance of this type of case and the impact it will have “culturally” on the entire nursing profession. These are not safety or risk professionals in this video, but you will find their concerns the same
I will reserve my comments so as not to influence your position. But watch the video, and then in the comments, let me know which school of thought you subscribe to: (1) the cognitive psychological school, or (2) the joint cognitive school
Reducing human error involves far more than taking disciplinary action against an individual. A range of measures is more effective controls, including the design of the equipment, job, procedures, and training. Actions for overcoming Active Failures
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
There is sound logic behind these, apparently not so obvious, egress requirements: IFC, 2018, Chapter 10: Means of Egress, 1010.1.9 Door operationsExcept as specifically permitted by this section, egress doors shall be readily openable from the egress side without the use of a key or special knowledge or effort. 29 CFR 1910.36(d)(1) Employees must
We are working to implement a formal root cause and corrective action process for a client. The industry has a very different view and approach to what I have come to know over the last 30 years as Human Factors. I think my friends “down under” are reading my mind or my articles at SAFTENG
