“As they depend, not upon the agent, but upon fortune, they cannot be the proper foundation for any sentiment” — Adam Smith We all believe that people should follow safety rules all the time. Not because there is a harmful outcome every time someone violates a safety rule or commits an unsafe act. Because usually [...]
“Human genius has limits, but stupidity does not.” — Alexandre Dumas, fils Everyone we have ever worked with is accepting, if not downright enthusiastic, about managing process safety.

“The failure of a layer of protection to prevent an incident is not the initiating cause of the incident.” The United States just joined much of the world in grounding the Boeing 737 Max 8 and Max 9. The tipping point was not the crash of Indonesian Lion Air Flight 610 into the Java Sea [...]
“No matter how bad things are, you can always make things worse.” — Randy Pausch The term “worst case” lacks rigor.

“Archeology is the search for fact, not truth. If it’s truth you’re looking for, Dr. Tyree’s philosophy class is right down the hall.” — Indiana Jones, from The Last Crusade A process hazard analysis (PHA) is not a trivial exercise. The search for process hazards takes time and effort, and it pulls a team of [...]
“There is almost no human action or decision that cannot be made to look flawed and less sensible in the misleading light of hindsight. It is essential that the critic should keep himself constantly aware of that fact.” — Lord Anthony Hidden One of the insidious effects of hindsight bias is that it puts much [...]
“Experience is a hard teacher because she gives the test first, the lesson afterward.” — Vernon Law When hit with the first winter storm of the season, everyone has to learn how to drive all over again.

“If you want zero risk in the plant, send everyone home and lock the gate.” — Industrial safety proverb I don’t remember when I first heard it, but I know I’ve said it. Risk is inherent to the chemical enterprise. We can reduce it, but we cannot eliminate it entirely. Zero risk is not an [...]
