On February 8, 2017, a foul condensate tank exploded at the Packaging Corporation of America paper mill in DeRidder, Louisiana, USA. The explosion killed three workers and injured seven workers. The non-condensate gas in the vapor space of the tank ignited by the welding fire. The explosion separated the tank from its bottom plate and launched it from its ground-level position up and over a six-story building, landing approximately 110 m away. The U. S. Chemical Safety and Hazard Investigation Board (CSB) released the final report on the cause of this incident on April 24, 2018. This paper describes the incident from the viewpoint of the explosion of the liquid storage tank based on the CSB report.
