A chemical leak at a plant in La Porte, Texas, left two people dead and another 30 injured on July 27.
Approximately 100,000 lb of acetic acid was released while maintenance was being performed at the LyondellBasell facility. Two contract employees were fatally injured, and 30 other personnel were transported to medical facilities for evaluation or treatment. One person remains hospitalized as of August 3.
An investigation team from the U.S. Chemical Safety Board is at the La Porte facility. The CSB, OSHA and LyondellBasell have signed an evidence and site control agreement to preserve evidence. The immediate area of the release is not accessible due the presence of hazardous materials released as result of the incident. The CSB investigation team remains on-site conducting witness interviews, documenting the incident scene and obtaining records to assist in the investigation.
LyondellBasell is a Dutch-based producer of chemicals and plastics.
