“The head of the hurricane research division, Hugh Willoughby, told me that hurricanologists can predict the behavior of storms if those storms behave predictably.” — Erik Larson Hurricane season is officially from June 1 to November 30, so it’s not officially over yet. A look at the Atlantic, however, shows no tropical depressions developing and [...]
“If I had a nickel for every time this happened, I’d have two nickels. Which isn’t a lot, but it’s weird that it happened twice. Right?” — Dr. Heinz Doofenshmirz Friends and acquaintances recently flooded my inbox with stories about a series of sewer explosions near the north riverfront of St. Louis. It launched several [...]
“It’s what you do next that counts.” — Lisa Mackay One of my favorite movies is The Great Waldo Pepper starring Robert Redford as a barnstorming pilot after World War I. One scene is seared into my memory. Waldo Pepper’s friend, Ezra Stiles, crashes during an air show. The crowd surges out to the wrecked [...]
“Love is like oxygen. You get too much, you get too high; not enough and you’re gonna die.” — Andy Scott, of Sweet OSHA standards define safe lower and upper limits to the concentration of oxygen in the atmosphere to which workers are exposed. The limits are a minimum of 19.5% and a maximum of [...]
“Beware of little expenses. A small leak will sink a great ship.” — Benjamin Franklin The most common hazard we encounter during a HazOp is a leaking pipe. Not the most severe and not the highest risk. Just the most common. But we always encounter it. Why? Because pipes leak. All pipes, whether or not [...]
“My life experience confirms that the U.S. government frequently overclassifies data.” — Michael Hayden When it comes hazardous (classified) locations—electrical classification—even seemingly sophisticated technical facilities often get it wrong. The issue isn’t with the class, or the group, but with the division. Getting the division wrong, though, can render a facility more hazardous than it should [...]
“Suffocation is a cruel way to go.” — Arlaina Tibensky I usually think of process safety hazards as being related to fire, explosions, or toxic releases. There is another process hazard, however, doesn’t necessarily depend on any of these. It’s asphyxiation—death due to an inability to get enough oxygen to the body. Asphyxiation is not [...]
“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 [...]
