CO2 as solid particles can cause electrostatic discharge! In September 1953, an aircraft fuel storage farm was taken into use in Niederstedem, Germany. The automatic fire extinguishing system, which used CO2, was demonstrated to visitors on the roof of the storage tank. The tank containing an explosive mixture suddenly ignited and exploded. 29 people lost…...

In this line of work, it will not take long to hear the phrase “Is it really worth it?” We hear it when developing our Corrective Action Plans after an Audit, a PHA, or an Incident Investigation. Everyone agrees that “we need to do something”; it’s the level of that something that splits the road…...
I see this set up all the time… a business declares a space a Confined Space (NOT a Permit-Required Confined Space), just a simple space that meets the definition of a CS; however, it does not have a hazard that would make the CS a PRCS. So the question is… Does a “DANGER” sign belong…...
I have updated (4/3/26) the presentation with the NFPA direction/requirements for using the Diamond on small containers. Yes, NFPA provides specific guidance on using the Diamond on containers smaller than 1 gallon. 4/3/26 – I added the explanation as to why Bulk HAZMAT containers (Tanker Trucks & Railcars) are exempt from OSHA’s “shipped containers” requirements…...
DISCLAIMER: I am NOT suggesting we do this; just asking the group for their thoughts on a challenge I got this week. In all the discussions about using NFPA 704 Diamonds on Secondary Containers, from laboratory squirt bottles to bulk storage tanks, today I was asked if DOT Placards could be used to label STATIONARY…...
I guess we are never too old to learn new tricks! This week, I came across a practice that I was 100% certain I was being “punked.” The practice is called “welding,” but it’s done on a Polyethylene Plastic tank! Technically, it meets the definition of “welding”… Welding is a fabrication process that joins materials—typically…...
Too many safety personnel are not sufficiently familiar with the critical role Vapor Pressure (VP) plays in managing hazardous materials. From our PPE Hazard Assessments, Respiratory Protection, to how we respond to these hazardous materials when there is a LOPC event involving them. But VP also plays a major role in how we DESIGN our…...
Over the past decade, we have received dozens of requests from both current and new clients seeking to move to 19% Aqua Ammonia, so the process is NO LONGER RMP-covered. (NOTE: OSHA only covers 44% or higher Aqua Ammonia; EPA begins its coverage at 20%). This is taking the “inherently safe” approach to process safety…....
