CSB Releases Final Report, LyondellBasell


On May 25, 2023, the U.S. Chemical Safety and Hazard Investigation Board (CSB)* released its final report on the July 27, 2021, fatal acetic acid release at the LyondellBasell** La Porte Complex in La Porte, Texas.

The CSB’s LyondellBasell report found that the inadvertent removal of pressure retaining components of a valve caused the release of 164,000 pounds of an acetic acid mixture, killing two contract workers. Additionally, one other contract worker and one company employee were seriously injured. The facility’s property damage, including loss of use from the incident, was estimated to be $40 million.

Statement from CSB Chairperson regarding LyondellBasell

About the LyondellBasell accident, CSB Chairperson Steve Owens said, “As this tragic incident shows, even a simple task can turn deadly if it is not performed properly. There have been similar incidents around the country involving plug valves being inadvertently taken apart when removing connected equipment. It is time to improve the design of these valves and take other protective actions, such as signage and training, before more workers are killed or injured.”
