“Earthquakes don’t kill people. Buildings kill people.” — Wendy Bohon, geologist How many times have you been in a hazard review discussing the potential for a particularly severe event when someone asserts, “Well, I’ve never seen anything like that happen.” As though their proclamation of “never” settles the question. I sometimes ask them how long [...]
“At the end of this day, one shall stand, one shall fall.” — Optimus Prime, Transformers: The Movie I have never been to a process plant that could continue running without electrical power. So, it is not uncommon to see a plant with two separate electrical feeds, each with their own transformers. On most days, [...]
“With a purposeful grimace and a terrible sound, he pulls the spitting high tension wires down.” — Buck Dharma, Blue Öyster Cult The preferred design of a safety function is one that deenergizes to trip. That is, a function that goes to the safe state when all sources of energy have been removed. The probability [...]
“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 [...]
“Prepare and prevent, don’t repair and repent.” – Author Unknown Most safeguards can be easily observed. They might be the mechanical guards that prevent one’s fingers getting ripped off by moving parts, the fences that keep unauthorized people out of a hazardous area, or the alarms that blare through the plant when the reactor reaches [...]
“The easiest way to solve a problem is to pick an easy one.” — Franklin P. Jones We love having choices. We hate making choices. What if we pick wrong? There is no shortage of people ready to tell us. It is always helpful to have criteria for choosing, or to be honest, to justify [...]
“You keep using that word. I do not think it means what you think it means.” - Mandy Patinkin as Inigo Montoya, in The Princess Bride I find the phrase “While we never anticipate a loss of cabin pressure…” incredibly annoying. To anticipate means to think of something that will or might happen in the [...]
“But how they can be charged with negligence because they were not wizards, appellant’s brief does not make clear.” — Osmond K. Fraenkel, successfully arguing before the New York Supreme Court, 1935 In a world where companies tout “Zero Incidents,” not as an aspirational definition of perfect safety, but as a measurable and achievable target, [...]
“Everything is impossible until it is done.” — Robert H. Goddard In 1921, annoyed with ignorant criticism, Robert Goddard published a piece in Scientific American in defense of the potential for travel to the moon. It’s always easier to say something is impossible than to address the potential of it happening. Double Jeopardy When someone [...]
“To have constructive conversations about … options, one needs to take a calm look at the numbers.” — David J.C. MacKay In addition to the usual hazards found in all jobs—transportation related fatalities, workplace violence, and slips, trips, and falls—the chemical process industries have three special hazards to worry about: fires, explosions, and toxic releases.
