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.

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 [...]

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 [...]

Things We Worry About: Plane Crashes

“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.” – [...]

Consider

“There is no greater evil than men’s failure to consult and to consider.”  Sophocles In our office, we write a lot of recommendations.  As a rule, we begin recommendations with the words “consider” or “confirm.” This isn’t because we’re looking for weasel-words. It’s because not every recommendation is the best idea. Some recommendations aren’t even [...]
