Dr. Sidney Dekker (Ph.D. in Cognitive Systems Engineering) states there are basically two (2) ways of looking at human error. In this article, I share with you, the first view, which could be called “the bad apple theory“. It maintains that:… Membership Required You must be a member to access this content.View Membership LevelsAlready a...

The strategic approach to improving human performance within safety embraces two (2) primary challenges: Anticipate, Prevent, Catch, and Recover from ACTIVE errors Identify and Eliminate LATENT organizational weaknesses that provoke human error and degrade controls against error and the consequences of error Preventable errors will not be eliminated if opportunities to err are not methodically…...

Human factors are concerned with optimizing human performance in all tasks and in major hazard workplaces; the primary intention is to achieve safe performance. These high-risk workplaces should have conducted risk assessments and established a range of controls to prevent major accidents. Still, they should also focus on human performance issues to eliminate or reduce…...

Several studies have evaluated the effectiveness of behavioral modification programs in improving workplace safety. These studies have focused on establishing the following: their ability to decrease accidents/injuries, their ability to increase safe behavior and which components in a behavioral observation safety processes are most important in changing unsafe behavior and reducing accidents and injuries… Membership...

One of my favorite examples of Human Factors Engineering is the Center High-Mounted stop Lamps. We have all seen them on every personal vehicle manufactured today. They are now a safety requirement. But it was not always that way. So, what is a CHMSL? CHMSL are red stop lamps mounted on the center line of…...

Human Performance Improvement (HPI) is the systematic process of determining desired performance, continually monitoring performance, discovering and analyzing performance gaps, designing and developing effective interventions, implementing these interventions, and continually evaluating the results of improvement interventions within performance monitoring to ensure that the improvement process takes place. The goal of excellence in human performance is…...

Humans are integral to the safe operation of a nuclear power plant. In the late 1970s, NRC began to focus on protecting and ensuring adequate training of plant staff to perform their assigned tasks. The NRC studied factors affecting performance, such as the effects of shift work on health and whether control room simulators would…...

Behavior-Based observation and feedback processes promote desired behaviors by introducing POSITIVE REINFORCEMENT for behaving safely. The positive reinforcement is provided through POSITIVE FEEDBACK. These programs are based on the ABC behavior model, as I explain below. The effectiveness of behavioral safety observation and feedback programs is dependent upon effective implementation. Assess Cultural Maturity or Readiness… Membership...

Human Reliability Assessments (HRA) start by analyzing operations proactively, looking at the types of potential human error and the probability of these happening. An organization must understand what effect such risk will have on safety. It needs to understand how to control or reduce human error so it’s As Low As Reasonably Practicable (ALARP). To…...
