Fail Safe: A Dangerous Misconception

“They’ve thought of everything. Everything, that is, but their own failure.”  — K. Austin Collins I recently watched the 1964 movie, Fail Safe, directed by Sidney Lumet. It reminded me of a dangerous misconception I frequently encounter during process hazard reviews. If you are not familiar with the movie, it came out shortly after the [...]

Process Design and Hazard Review: They Are Not the Same

“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 [...]

Probability of Failure: Power Transformer Reliability

“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, [...]

Power Failures: Back-Up Generator Reliability

“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 [...]

Safety in a Time of War

“Every gun that is made, every warship launched, every rocket fired, signifies in the final sense a theft from those who hunger and are not fed, those who are cold and not clothed.” – Dwight D. Eisenhower A safety professional I know recently looked at the photo above and commented, “Does that look safe?” Any [...]

Eternal Vigilance: Proof Tests are Essential to Safety

“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 [...]

Occupancy: Getting It Right

“I don’t worry about the bullet with my name on it. Can’t do anything about that. It’s the bullet addressed to ‘Occupant’ that I worry about.”  — Drew Schmidt I don’t get as much junk mail as I used to.  Now, I get junk emails and junk texts. When I do get junk mail, however, [...]

Process Risk: Learning from Experience

“We do not learn from experience…we learn from reflecting on experience.”  — John Dewey There are too many celebrities and philosophers to count who have talked about the importance of their mistakes in shaping them. Many seem quite pleased, even proud, of the mistakes they’ve made and their ability to rise from them and go [...]

KISS: Keep It Simple = Safety

“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 [...]
