“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. [...]
“To many, total abstinence is easier than perfect moderation.” —St. Augustine “Check valves are worthless.” Every engineer I know has heard that. Many believe it. Quite a few have said it. Yet, check valves are still made and installed. How worthless could they be? Why Use Check Valves? Check valves are designed to allow flow [...]
“None of this will be important if there’s a zombie apocalypse. But how likely is that?” —Jason Vladescu I was once at a conference where I overheard a conversation at the next table during lunch. The two of them were talking about PSAs. I quickly realized that they weren’t talking about Public Service Announcements. They [...]
“You are now statistically more likely to be elected president of the United States in your lifetime than you are to die in a plane crash. What an amazing achievement as a society! But what we end up focusing on are the catastrophic failures that are incredibly rare but happen every now and then.” – [...]
“Unlike Humpty Dumpty, the Secretary may not give a word whatever meaning she chooses.” —Judge Richard DeBenedetto When the Meer Corporation took the bold and relatively unheard-of step of contesting an OSHA citation for violating the Process Safety Management standard (PSM), no one expected them to prevail. The PSM standard includes an exemption for atmospheric [...]
“Chains of habit are too light to be felt until they are too heavy to be broken.” —Warren Buffett Caps and plugs serve no process function. It is a common practice to install a cap or plug on the end of a line that is open to the atmosphere, but the justification is for safety, [...]
“To invent the train is to invent the rail accident of derailment.” —Paul Virilio When most of us think of train derailments, we think of horrendous events, like the Lac-Mégantic rail disaster in 2013 that destroyed the town in Quebec and killed 47 people. Fortunately, the vast majority of train derailments associated with the chemical [...]
