Process Design and Hazard Review: They Are Not the Same

“A camel is a horse designed by a committee.”  — Alec Issigonis Good process design results in a process that is more likely to work. Great process design results in a process that is even less likely to not work. Great process design is not the result of compromise and trade-offs, but of a singular [...]

Probability of Failure: Power Transformer Reliability

“At the end of this day, one shall stand, one shall fall.”  — Optimus Prime, Transformers: The Movie I have never been to a process plant that could continue running without electrical power.

Power Failures: Back-Up Generator Reliability

“With a purposeful grimace and a terrible sound, he pulls the spitting high tension wires down.”  — Buck Dharma, Blue Öyster Cult The preferred design of a safety function is one that deenergizes to trip. That is, a function that goes to the safe state when all sources of energy have been removed. The probability [...]

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 [...]

Piling On: One More Safeguard?

“Some safety professionals, in the name of ‘zero-injuries’, will heap regulation after regulation on a job until the organization rebels and simply refuses to comply.”  — Phil La Duke There was a time when getting ready for winter meant making sure you had enough firewood to heat your cabin until spring. If you didn’t, your [...]

E-Stops: The “Get Fired Button”

“Panic is a natural response to danger, but it’s one that severely compounds the risk.”  — David Ignatius At 2:30 am, on Saturday, October 2, 2021, a split in the San Pedro Bay Pipeline began discharging oil into the Pacific Ocean off the coast of California. Low pressure alarms in the control room indicated that there [...]

Speed Of Thought

The degree of slowness is directionally proportional to the intensity of memory. The degree of speed is directionally proportional to the intensity of forgetting.” ― Milan Kundera, Slowness Every industry uses speed as a measurement to quantify productivity.  That productivity, whether gallons or railcar loads, is a tangible result that translates into revenue for a company.  Speed [...]

Batch Processes: Consider a Procedural HazOp

“We know we need civilization and laws and procedures, but isn’t it frustrating? Wouldn’t it be great if we could just do what we needed to do?”  — Lee Child When someone thinks about a Process Hazard Analysis, a PHA, they usually think about a Hazard and Operability Review, a HazOp. And when they think [...]
