ST. LOUIS – The Latest on the federal investigation into a deadly steam tank explosion in St. Louis (all times local):
9:30 a.m.
A federal report says a St. Louis company's steam condensation tank exploded, shooting into the air and through the roof of a neighboring business, after the tank was restarted despite needing emergency repairs.
The U.S. Chemical Safety and Hazard Investigation Board released findings Thursday of its investigation into the April 3 explosion at Loy-Lange Box Co. Four people were killed.
The van-sized tank first sprung a leak in November 2012. The federal report says a contractor made emergency repairs but Loy-Lange ignored a recommendation to replace part of the tank.
Engineers again noticed a leak on March 31. The system was shut down and a technician was scheduled to arrive April 3. But investigators say the system was restarted that morning, before the technician arrived, and apparently exploded on startup.
