“Show me a hero and I’ll write you a tragedy.” — F. Scott Fitzgerald Being a firefighter is about as safe as any typical job in the United States. Fighting house fires is safer. Fighting industrial fires, on the other hand, is about as dangerous as the most dangerous jobs that are legal. The Dangers [...]
“Differences challenge assumptions.” Anne Wilson Schaef There is a common misunderstanding about the nature of Process Hazard Analyses (PHAs): that they are objective studies. By objective, we mean that different teams, working at different times and at different places, but looking at the same process, will get the same results. There is a perception that [...]
“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 [...]
“Some risks are plainly acceptable and others are plainly unacceptable.” Supreme Court Justice John Paul Stevens When Justice Stevens wrote that opinion for the majority in the 1980 OSHA Benzene case, he went on to add that odds of fatality of one in a billion could not be considered significant but that for odds of [...]

“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. In our community, freezing rain coats everything, including the roads, which makes driving especially treacherous. A few years [...]
“Once trained, the hazard often becomes a routine part of their experimentation and researchers perceive themselves to be experts in handling the hazard. Perceived familiarity can shift the awareness level from cautiousness to complacency.” — University of California Center for Laboratory Safety It didn’t get much press. Science reported on it, as did Chemical & [...]
“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 [...]
“Constraints inspire creativity.” — Christopher Isaac “Biz”Stone, co-founder of Twitter I once asked a young engineer if he knew where the phrase, “Think Outside the Box,” came from. “Taco Bell?” he replied tentatively. I asked a few of my other younger colleagues and to a person they had no idea where the phrase came from. As [...]
“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.
