To address human factors in workplace safety settings, peoples’ capabilities and limitations must first be understood. The modern working environment is very different from the settings that humans have evolved to deal with. This section examines human characteristics that can lead to difficulties interacting with the working environment. The main factors involved include: Attention –…...
Last August I posted an incident where a 3rd party carrier unloading his/her NH3 truck to an LPG storage tank (SAFTENG Membership content). The contents of the LPG tank had to be burned/flared off which took around 60 hours. There were no injuries in that incident, but the consequences of such an error could be catastrophic. And unfortunately,…...

The topic of human factors (HF) is often times misunderstood and sadly sometimes not even a thought during a Process Design/Engineering Review or a Process Hazards Analysis. Now I know some of you will scream… “we are not a refinery” so there is no need for us to go to this level in our efforts…...

One of the best books in my career is the first edition of “Field Guide to Human Error Investigations” (pdf) by Dr. Sidney Dekker (Ph.D. in Cognitive Systems Engineering); which then became “The Field Guide to Understanding Human Error” (2nd Edition). Those of you in the Process Safety arena have some baseline knowledge of “Human…...

As we know “human factors” are specifically called in the OSHA’s PSM standard and EPA’s Risk Management Plan and even more specifically they are part of our Process Hazards Analysis (PHA). However, many do not understand what “human factors” are all about, so I thought I would share another picture I captured in my travels to…...

Since the 1980s, Active and Latent failures have been a major part of Human Factors Engineering, we have all done it at some point in our careers… an accident happens, and we go straight to the obvious ACTIVE FAILURES and point to those as the sole cause of the incident; until one day a more…...
