ATF investigators determined that the fire originated in the upper level of the engine room, portside aft. A paint locker was located in the area of origin, with various combustible materials stored both inside and outside the locker. Interviews with the vessel’s engineer revealed that a boot warmer had been plugged into an extension cord […]
This is a real-life story of Elimination vs. Engineering Control We see some odd designs in our work around the world, but recently we came across a setup that defied any logic for a relief valve design basis. For some reason, the OEM and Installer of this process equipment wanted it enclosed for “efficiency”; however,
I fight this battle every year! It’s usually a learning experience for people unfamiliar with chemical processing and ASME B31.3. But I do my best to ensure they understand how the 10-minute Pressure Test is done, and then how the Leak Testing is done. So today I decided I need to “test” my practice that
Chemical and refinery facility personnel open piping and equipment to perform routine maintenance, add/replace components, or modify pipe routing. The piping may contain hazardous material, such as flammable hydrocarbons, toxic chemicals, or thermally reactive chemicals. Safe work practices dictate the removal or mechanical isolation of hazardous material from piping and equipment (e.g., using valves or
In an earlier post tonight, I shared an OSHA Hazard Bulletin from 1993 titled: Chemical Exposures from Industrial Valve and Piping Systems. In that Bulletin OSHA, talks about the hazards and accidents related to workers opening processes. But there is another serious error we see often… Open Ended Piping. This is a serious NO-NO in
The risks in sampling activities can be off the charts without engineering controls, Administrative Controls, and PPE. This post shares my sampling system. I learned this the hard way, and I hope some will take this advice and reduce the risks when we ask operators to collect a sample from a “live process”. As I
During the morning of February 24, 2023, an unknown amount of hydrocarbons and hydrogen sulfide were released, fatally injuring an employee inside an enclosed building at an oil and gas facility in North Dakota. The hydrocarbons and hydrogen sulfide displaced the oxygen in the building, and the employee asphyxiated in the oxygen-deficient atmosphere. The employee
On December 19, 2022, at approximately 11:10 a.m., an accidental release of 22,000 pounds of anhydrous ammonia occurred from the NH3 refrigeration process at a food processing facility in Norwood, Massachusetts. Exposure to the toxic ammonia vapor fatally injured one contract worker and seriously injured another contract worker. In addition, the release caused about $4
This video demonstrates the lengths some will go to “get it done”. We can see two workers with fire extinguishers, positioning themselves on both sides of the pipeline as if they know what’s going to happen. These are NOT Hot Work “fire watches”; these workers are there to do just what they expected: put the
On June 14, 2021, at approximately 6:50 a.m., an accidental release of mineral oil occurred. The mineral oil ignited, causing a fire. The event resulted in $380 million in property damage and the permanent closure of the facility. Before the incident, the facility employed approximately 200 people. Leading up to the incident, the facility had
On December 3, 2020, at approximately 2:30 p.m., an accidental release of chlorine gas occurred at a plastics facility and seriously injured one employee. At the time of the incident, four (4) employees were involved in replacing an empty chlorine container with a full 2,000-pound (one-ton) container at the facility’s Ethylene Glycol unit. The unit
On July 24, 2020, at 1:20 p.m., an accidental release of approximately 100 milliliters of silicon tetrachloride seriously injured two contract workers. At the time of the event, contract workers were disassembling a 2-inch flange to remove a blind (a solid metal plate used to isolate equipment) before reinstalling a section of piping that had
