A chemical tank failure in May was preceded by a warning from an inspection contractor. The contractor had found the tank, located at a paper mill, to be not fit for continued service 10 months prior to the failure. Further details about the incident are available, including the findings of investigators.

The inspection contractor's assessment was made before the tank's deadly failure. The source has more information about the events surrounding the chemical tank failure, including the role of the inspection contractor and the timing of the failure.
