Since we are in a snow apocalypse here in the Midwest, I thought I would lose my mind hearing all the “weather professionals” declaring that with wind chills below zero, the roads will freeze as the salt won’t work below 15F. And I thought these were “science-based” professionals. TIP: Wind chill is how the temperature feels to us. IT DOES NOT DEFY THE LAWS of SCIENCE....

This was the headline in our local news after a chemical company failed to participate in a community meeting after their product leaked from a railcar sitting in a railyard about 4 miles from the plant. It took several days to get folks back into their homes; as you can imagine, they were unhappy. However, not attending a community meeting after an event tied directly to your chemical is hard to...

I have spent my career working with flammable liquids, and those who have followed my writings on the topic understand why I have stopped using 1910.106 as my baseline flammable liquid safety standard and instead began using either the IFC or NFPA 30. I have been involved in several serious events where atmospheric storage tanks had been “manifolded” together (oftentimes for reasons unknown...

The risk assessment process must identify what could cause harm in the workplace, who and how it could harm, and consider what control measures are required to reduce the risk to As Low As Reasonably Practicable (ALARP)and tolerable. Control measures that have been identified must be implemented, clearly communicated to personnel, maintained, and used properly. All risk assessments must be carried...

The environment, organization, economics, capabilities, technology, and regulatory context all change over time. This backdrop of continuous systemic change ensures that hazards and how they are managed are constantly changing. Progress on safety concerns anticipating how these kinds of changes will create new vulnerabilities and paths to failure even as they provide benefits on other scores. The...

Now, I’m 100% certain that Mr. Gogh did not have the safety profession in mind when he said the following, but it could not be more true in the context of our profession. Few professions need passion like that of the safety profession. Find me a world-class safety pro, and we will have one who is outwardly passionate about protecting the men and women who do the dirty and dangerous work. “Your...

Employee #1 was removing the Electronic Expansion Valve (EEV) from the hot gas bypass line. The line contained R-22 refrigerant and compressor lubricating oil at a pressure of approximately 100 pounds per square inch. NOTE: R-22...

29 CFR 1910.106(d)(2)(iii) specifies the maximum container size depending upon the category of flammable liquid and the type of material from which the container is made. However, it is not uncommon to see flammable liquids in plastic and glass containers that are larger than allowed by the standard. In many cases the chemical is in the container in which it was shipped to the facility. Nationally...

With Ohio being a state that allows recreational marijuana use, the construction of marijuana facilities has begun. The Fire Marshal in the state of Colorado created a task force to deal with the hazards of these facilities in CO. Using the International Fire, Building, and Mechanical Codes, they wrote an excellent document called Marijuana Facility Guidance. The document was based on the 2015 IFC,...

An oldy but a goody from years past…

On June 14, 2024, at 2:08 p.m., a 52-year-old firefighter with 19 years of firefighting experience died while fighting a fire on a front-end loader. The front-end loader’s left rear tire exploded, and the force struck the firefighter. The accident occurred because the FF was approximately four (4) feet from the tire when acombustion explosion occurred. The fire on the front-end loader heated the...

Chlorine dioxide (ClO2) gas is unstable and decomposes, sometimes violently, into Cl2 and O2 (with a 50% increase in gas volume). When storing chlorine dioxide (ClO2), it is commonly kept in CHILLED WATER because its solubility in water significantly increases at lower temperatures, making it more stable and allowing for higher concentrations to be safely stored; essentially, cold water helps to preserve...
