Consider: A Weasel Word?

“For having lived long, I have experienced many instances of being obliged, by better information or fuller consideration, to change opinions, even on important subjects, which I once thought right but found to be otherwise.” — Benjamin Franklin The first time you ever encountered a weasel word was probably when your mom said, “Maybe,” or [...]

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 [...]

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 [...]

Process Safety: Addressing Risk or Dread?

“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 [...]

Risk Reduction: Any Credit for Mechanical Integrity?

“People give us credit only for what we ourselves believe.”  — Karl Gutzkow Several years ago, in a paper and presentation to the Global Congress on Process Safety (GCPS), PSM experts from OSHA observed that while it is common to see a mechanical integrity (MI) program listed as a safeguard in a PHA, this is [...]
