“It is with our passions as it is with fire and water; they are good servants but bad masters.” — Aesop A common trope of Hazard Communication training is for the instructor to share an SDS of “dihydrogen oxide” with the class and to review all the dangers of this “hazardous chemical”. Then, in a [...]
“Maybe tone it down with the explosions.” — Michael Bay Most of what we know about explosions is wrong. Most of what we “know” about explosions is what we’ve learned from the movies, which is the only thing called an explosion that we ever see. But what we see in the movies are not explosions, [...]
“A camel is a horse designed by a committee.” — Alec Issigonis Good process design results in a process that is more likely to work. Great process design results in a process that is even less likely to not work. Great process design is not the result of compromise and trade-offs, but of a singular [...]
“But, after all, no safeguards are adequate, unless the will to give effect to them fully is present.” — Jawaharial Nehru I had a truly embarrassing experience a couple days ago. I got a flat tire. The flat tire itself wasn’t embarrassing. Annoying, yes, but not embarrassing. There are road hazards, and even the most [...]
“Simplicity is prerequisite for reliability.” — Edsger Dijkstra For most of my life, I have struggled to keep down to a healthy weight. It didn’t help when someone told me, “Losing weight is simple. Eat less.” When I protested, they replied, “I said it was simple. I didn’t say it was easy.” The safest plant [...]
“The risks that scare people and the risks that kill people are very different.” — Peter Sandman I often wonder if work in process safety is a misallocation of resources. The leading cause of work-related fatalities is transportation, at about 40%. The next three (of seven causes identified by the Bureau of Labor Statistics), all [...]
“We know we need civilization and laws and procedures, but isn’t it frustrating? Wouldn’t it be great if we could just do what we needed to do?” — Lee Child When someone thinks about a Process Hazard Analysis, a PHA, they usually think about a Hazard and Operability Review, a HazOp. And when they think [...]
“I have always fancied that the end of the world will be when some enormous boiler, heated to three thousand millions of atmospheric pressure, shall explode and blow up the globe… They [the Americans] are great boiler makers.” — Jules Verne I was recently asked about using hot oil instead of steam to heat process [...]
“All things are poison, and nothing is without poison; the dosage alone makes it so a thing is not a poison.” — Paracelsus Have you ever noticed that news accounts about incidents in the process industries never talk about “chemicals”? No, the writer always refers to “toxic chemicals”. As though you can’t say one without [...]
“Electricity can be dangerous. My nephew tried to stick a penny into a plug. Whoever said a penny doesn’t go far didn’t see him shoot across that floor. I told him he was grounded.” — Tim Allen When I was fresh out of grad school, I had a job in process development. One project involved [...]
