Understanding the electrical classification model
Three (3) fundamentals are behind the “electrical classification” model for hazardous locations.  These three fundamentals mirror our approach to other workplace hazards, and understanding these three fundamentals will help make a lot of sense out of NFPA 497/499 and 1910.307. … HomeRead More »

Comparing Classes/Divisions with Zones
The US still uses the Class and Division system to classify electrical systems in hazardous locations.  However, outside the US, the Zone system is more widely used.  Manufacturers are beginning to list their equipment based on the Zone(s) it is rated for, which can cause translation confusion.  The table below may be of help. … HomeRead More »

CONSISTENCY matters in HFE (Colors)
I have mentioned this fundamental HF design need in several of my postings.  CONSISTENCY is key in helping reduce human error.  I like to use STOP signs as my example.  But here are some fundamental principles when analyzing computer screens, workplace signs, etc., when it comes to COLORS… … HomeRead More »

Runway Safety Trends and Runway Incursion Analysis
We can learn a lot from Aviation Safety!  I came across this 2017 presentation on Runway Safety Trends and Runway Incursion Analysis and just loved how they analyzed their data to identify the trends, causes, and contributing factors.  Some of the data may be alarming, but that is not my intent.  This is how we should be analyzing our data in industrial safety. It really drives home...

NTSB preliminary report on the Ground Worker being sucked into jet engine
I have spent much time reading NTSB accident reports over my career.  They are usually very educational, even for those of us outside the aviation industry.  This incident involving this mother of three being sucked into a jet engine has captured a lot of headlines due to its graphic nature, but there will be so much to learn from this incident in the coming months/years.  So far what...

Does this video show work inside a PRCS or an "industry practice"?
I have several clients who offload ships/containers in this manner. Whenever I see this, I immediately go to “that is a PRCS”. The ship/container is for sure a CS, and the fact that we have an engine putting off CO inside the ship/container makes the space a PRCS. I am fortunate enough to have great clients who think about it and have agreed there is a risk in practice. But last month,...

OSHA announces a revised PSM standard and an Emergency Response standard is coming this year (2023)
Yesterday, OSHA announced its plans to promulgate a revised Process Safety Management (PSM) standard and a NEW Emergency Response Standard in 2023. Executive Order 12866 requires the semiannual publication of an agenda of regulations listing all the regulations the Department of Labor expects to have under active consideration for promulgation, proposal, or review during the coming one-year period....

OSHRC vacates four (4) Heat Related citations against the USPS
The OSHRC has vacated four (4) heat-related OSHA citations against the United States Post Office.  This decision was based ON LEGAL matters regarding the Feasibility of Abatement of the Hazard.  ALL parties agreed to the fact that HEAT CAN BE A HAZARD, but when OSHA issues a GDC Citation, it must provide feasible abatement measures.  The ALJ and OSHRC agreed that the abatement measures...

Human Factors Engineering and your ATM Card
Most adults have used an Automated Teller Machine (ATM) card in their lifetime.  But these machines, as high-tech as we imagined they were back in the day, had a design flaw that caused a lot of users a lot of trouble.  Human Error Problem:  ATM users would insert their cards, request cash, take it, and walk away, leaving their cards behind. Solution: a “forcing function”...

Vent & Burn @ East Palestine Derailment
The derailment in East Palestine, OH, was a classic need for a Vent & Burn operation (as shown in the video).  There was some indication that one or more of the Vinyl Chloride railcars had begun its polymerization reaction, which could result in catastrophic consequences for many people and property.  This indication also eliminates the option of transferring the VCM to other containers. ...

Simple Engineering Control to allow failing safely (Gas Pump drive offs)
I share this in my training classes as this is an example that most adults can relate to… We have all seen pics and videos of humans forgetting to remove the fuel hose from their vehicle and driving off, often creating serious hazards.  But about 20 years ago, a very simple device was invented that allows this human error to “fail safely.”  This simple device is an “ENGINEERING...

Organizations are perfectly tuned to get the results they are getting (Muschara, 2018)
This is one of my favorite principles of Human Factors. But be careful sharing this, as most organizations with an immature SMS do not like it when they realize the truth of this principle and its statements about the organization. Organizations are perfectly tuned to get the results they are getting … HomeRead More »
