The Next Thing You Know: PSM-Covered Warehousing

“On the first day of school, you got to be real careful where you sit. You walk into the classroom and just plunk your stuff down on any old desk, and the next thing you know the teacher is saying, ‘I hope you all like where you’re sitting, because these are your permanent seats.’”  — [...]

Combustible Dust Tests: Now What?

“To err is human, to forgive, divine.”  — Alexander Pope I was in a PHA once where the lone operator on the PHA team finally grew weary of the discussion of operator error.  “Why is it that when you engineers make a mistake, you call it design error, but when I make a mistake, you [...]

PSSRs: Commissioning on Steroids?

“Ideas are commodity. Execution of them is not.”  — Michael Dell I’ve always believed that a poor plant design, brilliantly operated and maintained, is far safer than a brilliant plant design, poorly operated and maintained. A pre-startup safety review (PSSR) is OSHA’s way of starting a facility down the path toward brilliant operation and maintenance. [...]
