Keyed-Valve Interlocks

  Several years ago, while working in a refinery, I noticed a relief valve with its inlet block valve completely closed. I radioed an operator for assistance. Within minutes, two operators arrived and confirmed that the valve should not be closed. They opened the valve and thanked me for notifying them. In following up a…

Considerations when Establishing a Mechanical Integrity Program for a Process Safety Management Regulated Facility

Energy organizations such as chemical manufacturers, oil and gas production, and even pharmaceutical manufacturers strive to maintain a Process Safety Management (PSM) program to ensure the safety of their employees and those around their facilities. Many of these organizations are familiar with the requirements of PSM including the process of conducting Process Hazard Analysis (PHA)…

PHAs and Flare Systems

At every facility, there is a point during the process hazard analysis when the team inevitably dives into “the black hole” of flare/relief/scrubber systems.  Following strict HAZOP analysis methodology, a team documents all deviations from normal operating limits.  However, with most relief systems, this leaves the team facing numerous causes, and with each source, having…

Group & Self Accountability in Process Hazard Analyses

When performing a process hazard analysis (PHA), often people of different positions and specializations are gathered in the meeting room to assess the chosen process on its safety and ability to safeguard against inherent hazards. These groups can include personnel from maintenance, operations, engineering, HS&E (Health, Safety, and Environmental), and management. This diversity of thought…

No…You Will Never Use That in the Real World, but That’s Not the Point!

The point of education is not just to learn facts or be able solve math problems, but to develop skills that make us better, more well-rounded individuals. So, with that said, the next time that a recent college or high school graduate complains about having had to learn, “things they will never use again,” remind them that the critical thinking and reasoning skills that they developed are more important than the actual information they had to study.
