PHAs and LOPAs: What Would You Recommend?

“I don’t have a particular recommendation other than that we base decisions on as much hard data as possible.”  — Dorothy E. Denning The best waiters are the ones who are willing to make recommendations when you ask.  Anything but, “Well, everything is good.” Because, admit it, everything is not. And then, when you try [...]

Previous Incidents: Learning from Mistakes

“The only real mistake is the one from which we learn nothing.”  — Henry Ford I know a young woman whose relationships are in a constant state of turmoil. She keeps picking the wrong guys and each relationship ends in heartbreak. “Why do I keep making the same mistake over and over?” Why indeed? I [...]

3 Criteria for Picking LOPA Scenarios

“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 [...]

Breaking Up Is Hard to Do: HazOp Nodes

“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 [...]

We’re Not Wizards

“But how they can be charged with negligence because they were not wizards, appellant’s brief does not make clear.”  — Osmond K. Fraenkel, successfully arguing before the New York Supreme Court, 1935 In a world where companies tout “Zero Incidents,” not as an aspirational definition of perfect safety, but as a measurable and achievable target, [...]

Seven Questions: The Essence of HazOps

“A prudent question is one-half of wisdom.”  — Francis Bacon There are about a gazillion “best” ways to do HazOps. What they all have in common, however, is that they use worksheets that are set up as tables that look at deviations in a node. For each deviation, a HazOp team considers “Causes”, “Consequences”, “Safeguards”, [...]

Doing HazOps the RIGHT Way!

“Watching two engineers argue is like watching pigs wallow in mud. Eventually you figure out that they do it because they like to.”  — Anonymous I’m still learning better ways to do HazOps. And since there are better ways, then what I am doing now couldn’t possibly be the best. So, what is the RIGHT [...]

Lab Safety: A Three Phase System

“A pint of sweat will save a gallon of blood.”  George S. Patton, Jr. I intended to begin with “A good plan, well executed, is better than a perfect plan, poorly executed,” but when I checked, that’s not what General Patton said.  What he said was “A good plan, violently executed now, is better than [...]

Double Jeopardy: Impossible?

“Everything is impossible until it is done.”  — Robert H. Goddard In 1921, annoyed with ignorant criticism, Robert Goddard published a piece in Scientific American in defense of the potential for travel to the moon. It’s always easier to say something is impossible than to address the potential of it happening. Double Jeopardy When someone [...]

Why Different PHA Teams Get Different Results

“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 [...]
