On February 19, 2015, employees were to perform a preventive maintenance inspection inside of a scrubber, which is maintained free of oxygen using a nitrogen blanket. When the designated attendant could not find the entrant employee, other employees searched for him. The entrant employee was found inside the scrubber (a metal tube) where he had…...

The process in progress at the time of the event was the manufacture of methatrexate, an anti-cancer drug. Shortly after employee #1 began to draw bromine liquid into the supposedly clean and empty charging pot, he heard a hissing sound. He then saw a purple haze spewing out from under the lid of the pot…....
When we use the phrase “cascading failures,” this event is nearly a perfect example. 1) A gas station employee attempted to fill a propane tank without the required training. This led to the uncontrolled release of approximately 1500 liters (396 gallons or 1,600 pounds) of liquid propane and evacuated nearby homes. 2) When the staff…...
An explosion occurred inside a mobile trailer containing five (5) gas-fueled clothing dryers at a fruit orchard and processing facility. The blast caused damage to the building, and the facilities manager, who was inside when it took place, received burns and contusions. In 2019, the gas-fueled clothing dryers were installed and converted from natural gas to…...
In recent years, we have seen many facilities begin to fill their own PIT LPG cylinders on-site rather than contract this service out. Typically, we find this “change” was poorly managed: no PPE Hazard Assessment, no (or very poor) training on the task, LPG improperly located, improper electrical classification around the LPG tank and the…...

During my time in the process industry, we usually had a “caustic scrubber” attached to our PSM/RMP covered process(s). This meant this scrubber was “part of” the covered process. I get a lot of pushback regarding covering “safety critical utilities” that are in place to either PREVENT, PROTECT, or MITIGATE an event from the covered…...

We routinely discuss the challenges and risks of performing Line/Equipment Opening (LEO) tasks, with one of the top 5 challenges being the “means used to verify” the pipe/equipment is at a Zero-Energy-State (ZES). The factors that occurred in this incident probably happens by the hour in the process industry; it is why we ALWAYS have…...

Looking at the contractor involved with the refinery H2S incident last week, I came across another refinery accident involving H2S where this contractor had their employees exposed.

Regardless of what CSB highlights in this video… TORQUE VALUES MATTER and having your Emergency Escape Respirator on your person all played a role in this accident! Also, SIMOPS is a term discussed the video. CLICK HERE to see a great, and FREE, safety document explaining SIMOPS from our friends at the CCPS. I also…...
This case is interesting, as I have always challenged the concept that an engine room (membership required)with large roll-up utility doors and windows and personnel/fire doors that are found propped open more often than not would contain the “catastrophic release of NH3”. It seems this EPA inspector was one who attended one of my 5-Day…...

If we spend enough time in chemical plants, we will encounter a widespread, albeit severe, human failure regarding a “safety-critical instrument.” I am referring to the IMPROPER placement of personal gas monitors. Nine times out of 10, where do we find these personal gas monitors on the worker’s body? I am betting your experiences are…...
