A federal report has shed light on a tragic incident that resulted in 11 fatalities. The failure of a chemical tank led to a massive release of caustic liquid, causing significant damage. An inspection had previously deemed the tank unfit for use, but no repairs were made.

The incident is still under investigation, with the cause of the failure yet to be determined. Recommendations for repairs and inspections were provided, but not acted upon.

Further details about the incident and the ongoing investigation can be found in the federal report released by the U.S. Chemical Safety Board.
