“Minimizing your exposure to pathology goes a long, long way.” — Dr. Susan Biali Haas When a sensor faults, it doesn’t stop providing information. It’s just unreliable information. It may be correct, it may not, but it is not to be believed. Like a clock that has stopped but is still correct twice a day, [...]
“Shallow men believe in luck; wise and strong men in the cause and effect." – Ralph Waldo Emerson In process safety, one important aspect of assessing risk is determining what safeguards are in place to protect against a hazard. Often, we see teams credit human response as a safeguard, sometimes relying on the response as [...]
“What’s the use you learning to do right when it’s troublesome to do right and ain’t no trouble to do wrong, and the wages is just the same?” — Mark Twain, in The Adventures of Huckleberry Finn We love to hate regulations. The harder it is to comply with them, the more we hate them. [...]
“Life is a journey and not a destination.” — Lynn H. Hough When Richard Nixon signed OSHA into law in 1970, the United States was looking at 14,000 work-related fatalities per year. With a workforce of about 70 million full-time equivalents, the work-related fatality rate was about 20 fatalities per 200,000,000 hours worked. In 2018, [...]
“You’re a hero one day, you’re a villain another day.” — Vincent Tan Every good story is a story of conflict. It has a villain. It has a victim. And in the best stories, it has a hero. The story of a process incident or scenario is no different. It has villains—causes. It has victims—receptors, [...]
“The easiest way to solve a problem is to pick an easy one.” — Franklin P. Jones We love having choices. We hate making choices. What if we pick wrong? There is no shortage of people ready to tell us. It is always helpful to have criteria for choosing, or to be honest, to justify [...]
“Come on, baby, let’s start anew, ‘cause breaking up is hard to do.” — Neil Sedaka Before a HazOp team ever assembles, the facilitator has some important tasks to complete: get agreement with management on the scope of the review, identify the boundaries of the study, and break the process up into nodes. And breaking [...]
“Nor should participation trophies be offered for simply showing up.” — Kevin Dickenson OSHA is fond of pointing out that the Process Safety Management Standard, 29 CFR-1910.119 (PSM), is a performance-based standard. While they generally avoid telling us how to comply with standard, they expect us to comply with standard, nonetheless. There is no prize [...]
“We must accept human error as inevitable - and design around that fact.” — Donald Berwick The idea of human error and its contribution to industrial incidents has been the center of debate in recent years. If you’ve been part of more than one incident investigation, you’ve probably experienced an incident being attributed to human [...]
“Fear is often our immediate response to uncertainty.” — Gabrielle Bernstein In 2001, when the CCPS book, Layer of Protection Analysis: Simplified Process Risk Assessment, “the purple book”, stated that human response is “a relatively weak protection layer” and “less reliable than engineering controls”, many people were willing to accept that piece of conventional wisdom.
