In this episode, Molly and Jo discuss the CSB's final investigation report on the 2021 fatal acid release at LyondellBasell La Port Complex in La Porte, Texas. On July 27, 2021, contractors inadvertently removed pressure retaining components of a valve, releasing 164,000 pounds of acetic acid mixture, which fatally injured two contract workers. Today, Molly and Jo provide some background information on LyondellBasell and the substances involved in the release, talk about what exactly happened at the time of the incident, and discuss what a valve actuator is and why contractors were trying to remove one that day. Then they discuss other incidents that the CSB identified where similar mistakes were made with plug valves and removal of pressure retaining components, touch on the contributing factors, and talk about what other companies can learn from this incident. Finally, they cover the CSB's recommendations, which include those addressed to LyondellBasell, the contract company, and to various RAGAGEP entities.
