KISS: Keep It Simple = Safety

“Simplicity is prerequisite for reliability.”  — Edsger Dijkstra For most of my life, I have struggled to keep down to a healthy weight. It didn’t help when someone told me, “Losing weight is simple.

It’s Magic: Documentation and Certification in PSM

“You don’t need to say any special incantation or sacrifice a stray cat or something first.”  — Kevin Hearne A common complaint about complying with OSHA’s Process Safety Management standard, 29 CFR 1910.119, is about the tremendous effort that goes into preparing all the required documentation and keeping it up to date. It is ironic, [...]

Process Safety: Addressing Risk or Dread?

“The risks that scare people and the risks that kill people are very different.”  — Peter Sandman I often wonder if work in process safety is a misallocation of resources. The leading cause of work-related fatalities is transportation, at about 40%. The next three (of seven causes identified by the Bureau of Labor Statistics), all [...]

Work-Related Fatalities in the Year of Covid

“Maybe this virus has a silver lining.”  — Katherine Plumhoff The Bureau of Labor Statistics releases its workplace safety statistics for the previous year each December.
