“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 [...]
“We have first raised a dust and then complain we cannot see.” — George Berkeley You don’t need to be convinced that combustible dusts are hazardous. You’ve seen the photographs of demolished grain elevators, of the Imperial Sugar plant in Port Wentworth, Georgia looking like the Dresden firebombing in World War II. You’ve heard about [...]
“I’m an actor… I do a job and I go home. Why are you interested in me? You don’t ask a truck driver about his job.” — James Gandolfini I’ve been struck recently by how much we don’t talk about process safety once the hazardous chemicals we make have been loaded and shipped. Process Hazard [...]
“It is these properties that make materials so useful that also pose hazards to health and property.” — Peter Lodal Liquid nitrogen has some wonderful properties. It is really, really cold, so it is great for flash freezing delicate items. When vaporized, it helps maintain non-flammable mixtures, even when flammable vapors are present. Because it [...]
“Build a man a fire, and he’ll be warm for a day. Set a man on fire, and he’ll be warm for the rest of his life.” — Terry Pratchett The most common fire in a process plant is a pool fire. A pool of flammable liquid, something that exists normally or, more likely, something [...]
“For what it's worth, a good streak doesn't jinx you, and a bad one, unfortunately, does not mean better luck is in store.” — Leonard Mlodinow When someone tells you that they took a calculated risk, they almost certainly are not speaking the truth, to you or to themselves. That’s because there were almost certainly [...]
