Three people were killed and four more were injured Monday in St. Louis’ Soulard neighborhood when an explosion sent a boiler flying from one business and through the roof of another more than a block away.
One person died at the Loy-Lange Box Company, where the explosion occurred, according to St. Louis Fire Department Chief Dennis Jenkerson, and two others died at Faultless Healthcare Linen, where the boiler crashed through the roof. Four other people were taken to the hospital, Jenkerson said.
The explosion occurred at about 7:30 a.m. and launched the cast iron boiler, which weighs about a ton and a half, some 500 feet.
Police identified one of those killed as Kenneth Trentham, 59. City records show that Trentham had been one of the licensed engineers at Loy-Lange, a spokeswoman for the mayor’s office said.
There were no other details released on the others killed or injured.
A third building, occupied by the Pioneer Industrial Corp., sustained damage from a piece of flying pipe, but no one was injured there.
Investigators are seeking surveillance footage from the area that might have captured the explosion.
The U.S. Occupational Safety and Health Administration also sent representatives to investigate the blast.
