To accurately understand pressure measurements in industrial safety and process engineering, it is essential to distinguish between absolute pressure and gauge pressure, as well as the units commonly used for low-pressure monitoring (such as draft gauges or vacuum systems). The following table provides the conversion relationships between these units, referenced against standard atmospheric pressure at…...
I have worked with three (3) organizations in the past 5 years on their efforts to make H2 an everyday fuel for household appliances, vehicles, and industrial fuels. Each project was a huge learning experience for everyone! But I am a lover of “codes” to establish the baseline design, construction, operation, and maintenance. I looked…...
We keep hearing how the tragedy in WA state at the Papermill was some type of tank implosion and then explosion. I have serious doubts about that theory. I think this was just a simple seam/weld failure, possibly caused by Stress Corrosion Cracking (SCC), but I am sure the CSB will get to the bottom…...
An odor incident at the Gallipolis Water Treatment Plant was triggered by the accidental mixing of two treatment chemicals during a delivery. The incident was isolated entirely to the plant, and officials confirmed there was no threat to the public water supply or drinking water. Incident Breakdown… Membership Required You must be a member to...
So I was curious as to how a 900,000-gallon white liquor tank could catastrophically fail. I am certain we will learn how this specific failure occurred, but I am not convinced the learnings will be shared broadly if the CSB does not get involved. With this much damage to people and property, there will be…...
In the context of a Safety Management System (SMS), auditing is the systematic, independent, and documented process for obtaining objective evidence and evaluating it against established criteria to determine the extent to which requirements are fulfilled. I recently had a lengthy discussion with the executive team regarding my PSM/RMP audits over the years. These men…...
A ship’s engineer sustained cold burns to 10–13% of his body surface after liquid propane was released without warning in the early hours of 1 November 2018 during loading operations. A flammable gas cloud could have resulted in a catastrophic explosion if ignited. The worker was treated at the hospital and subsequently repatriated to Russia,…...
We get so much slack when we push Hydrostatic Pressure/Leak Testing vs. Pneumatic testing. So many think that pneumatic is easier and cheaper, when in reality it is NOT. In fact, the B31 series makes it clear that HYDROSTATIC is the first choice for pressure and leak testing. The code makes it clear that pneumatic…...
FMO Releases Preliminary Findings in Robbins Lumber Fire and Explosion Investigation FMO Investigators and ATF Special Agents worked throughout the Memorial Day weekend at the scene of the Robbins Lumber fire and explosion in Searsmont. During that time, personnel paused to honor Morrill Firefighter Andrew Cross and remember military members who made the ultimate sacrifice…...
Prayers to all involved, but things at the WA State Paper Mill are looking far more serious than what the media is saying. This is looking like a “white liquor tank” event based on the images I have seen (SAFTENG members can see them below). Emergency responders have confirmed: 10 individuals were transported to area…...
OSHA, IFC, and NFPA have “separation distance” requirements for flammable liquid storage tanks. These requirements have been around longer than I have been dealing with hazardous materials and process safety, and yet we always come across some wildly out of “compliance” arrangements of these flammable liquid tanks. using OSHA’s Flammable Liquid Standard 1910.106 we can…...
On April 30, 2026, a miner, 2, with 4 weeks and 2 days of experience at the mine, died while filling a water trailer when it overturned. MSHA is still investigating. This is their preliminary report…. Membership Required You must be a member to access this content.View Membership LevelsAlready a member? Log in here...
