“You know what’s the greatest part of anything ever in the history of everything? Exaggeration. No wait; it’s correcting yourself. No, better yet, it’s making lists.” — Demetri Martin When Google offers an AI response, it includes a statement: “AI responses may include mistakes.” That was never so obvious to me as when I posed [...]
“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 [...]
“It is your concern when your neighbor’s wall is on fire.” — Horace On November 26, 2025, a fire enveloped a high-rise apartment in the Wang Fuk Court complex that was undergoing significant renovation.

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 [...]
“Before the first atomic bomb test, scientists took the time to calculate whether the blast would ignite the nitrogen in the Earth’s atmosphere and incinerate us all. The risk was low and the test went off, but Rees wonders what the odds would have had to be to discourage the bomb makers.” — Dennis Overbye [...]
“A rule without exceptions is an instrument capable of doing mischief to the innocent and bringing grief—as well as injustice—to those who should gain exemptions from the rule’s functioning.” — Derrick Bell I don’t remember when I first realized that there is a difference between process safety management and Process Safety Management.

“At this time, we have not located any survivors.” — Chris Davis, Humphreys County Sheriff Not long ago, I was at a plant to facilitate a HazOp and LOPA for one of their processes.
