On September 5, 2023, at approximately 7:30 p.m., an accidental release of butadiene vapor occurred inside a decanting tank (“tank”). The butadiene vapors ignited, resulting in a fire that seriously injured one employee. The incident occurred in a latex production area during a maintenance shutdown. Employees were tasked with removing an internal part (a “baffle”)…...
On May 4, 2023, at 6:25 a.m., approximately 790 pounds of a hydrocarbon mixture containing about 7,000 parts per million (ppm) of hydrogen sulfide were accidentally released at a Refinery. Exposure to the toxic hydrogen sulfide vapor seriously injured one employee. The facility’s investigation found that, on the day of the incident, pressure in a…...
On Friday, February 3, 2023, at approximately 10:46 p.m., a flash fire was accidentally released from a product purge vessel (“vessel”) flange during planned maintenance activities. The fire seriously injured four (4) contract workers. On January 29, 2023, the facility shut down its polyethylene unit for planned maintenance. Following the shutdown procedure, operators purged and…...
On September 22, 2022, at approximately 9:00 a.m., a liquid mixture comprised of aniline, formalin, and hydrochloric acid was accidentally released, seriously injuring one contractor at a chemical manufacturing facility in Geismar, Louisiana. On September 20, 2022, two days before the incident, an off-site power outage caused an immediate loss of process flow into the…...
On October 1, 2020, at approximately 9:00 a.m., approximately 554 pounds of chlorine gas were accidentally released. Exposure to the toxic chlorine vapors seriously injured one employee. At the time of the incident, four (4) workers (two unit employees and two contractors) were trying to stop a chlorine leak (described as a fugitive emission) from…...
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 been removed and cleaned. This type of equipment opening is commonly referred to as a “line opening” or “performing a line break.”…...
Scenario: Employees bring rechargeable lithium-ion batteries from home to the workplace for use in e-cigarettes, which are not used in any equipment or devices related to their work duties. You also state that, in this scenario, the battery terminals are unprotected and the employee or employees improperly carry these batteries in their pants pocket, a…...
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…...
