“What a pure blessing it was to have a bath in a tub alone in a room where all you had to do was pump the water, not tote buckets.” — Nancy E. Turner Somewhere in every process facility, liquids flow through pipes. Sometimes that flow is pulled by gravity. Some facilities push the liquid [...]
“We sometimes freeze the specimen with liquid nitrogen, which is extremely cold, you know. This is another technique we use now – but the specimens are not alive.” — Lennart Nilsson I recently facilitated a HazOp where the process required both very hot heat transfer media (steam and hot oil) and very cold heat transfer [...]
“Don’t be misled by History, or any other unreliable source.” — Will Rogers I remember when I lost faith in safety data sheets – SDSs. Well, they were called Material Safety Data Sheets – MSDSs – then. I was a young engineer, and the only engineer, at a start-up. My boss, the owner, assigned me [...]
“To be beyond any existing classification has always pleased me.” — Boyd Rice Every distiller understands that they are working with extremely explosive hazards. There is ethanol, a flammable liquid. And there is milled grain, a source of combustible dust. Despite this, when I visit distilleries, I often see areas that should be electrically classified [...]
“More often than not, to blame someone else is to play ‘hot potato’ with something that’s neither hot nor a potato.” — Craig D. Lounsbrough Imagine you work at a plant that makes a polymer. One of the raw materials is the monomer and it is toxic, reactive, and flammable. It contains an inhibitor to [...]
“I have a horror of being in confined spaces.” — Hayley Mills At a craft distillery that is not too far from Bluefield’s offices, the owner spoke about his need to climb into the pot still to clean out the stillage, especially the spent grains. He saw me wince and said, “Yeah, I know. It’s [...]
“Ventilation is the profound secret of existence.” — Peter Sloterdijk Most people, when hearing about the legal limits of ethanol, will think of Blood Alcohol Concentration (BAC). Except for Utah, where the BAC limit for driving is 0.05%, the BAC limit in the United States is 0.08%. That applies to drivers that are 21 years [...]
“Ignorance is not too dangerous. If you combine it with power, then this is a toxic mix.” — Yuvai Noah Harari Not surprisingly, eighteen of the thirty incidents in Volume 3 of the Chemical Safety Board’s series on incident reports addressed incidents at refineries and large chemical complexes. One incident in Volume 3, though, was [...]
“Perfection is not attainable, but if we chase perfection, we can catch excellence.” — Vince Lombardi I don’t believe that I have ever facilitated a perfect PHA. The question is, how would I recognize it if it was perfect? And would others agree? What exactly is a perfect PHA? A PHA Identifies Hazards The primary [...]
“If you can’t take the heat, get out of the kitchen.” — Harry S. Truman For decades, I’ve told people that OSHA requires thermal protection on surfaces over 140°F (60 C) up to a height of 7 feet. People just accepted that because a) I was the expert and b) it made sense. Recently, though, [...]
