ST. LOUIS (AP) - St. Louis Fire Chief Dennis Jenkerson says a boiler that killed one person when it exploded at a box company in St. Louis flew about 500 feet before crashing through the roof of a nearby laundry business, killing two more.
The boiler exploded Monday morning at the Loy-Lange Box Co. Four other people were injured and at least two are in critical condition.
A third person at Faultless Healthcare Linen was pinned under the boiler but fire department responders were able to free that victim.
Jenkerson says the boiler was a cast iron cylinder about 8 or 9 feet long and 4 feet in diameter, weighing about 1 1/2 tons. He says it was about the size of a van.
A piece of pipe about 8 feet long pierced the roof of the nearby Pioneer Industrial Corp., but no one was injured there.
Scott Allen with the U.S. Department of Labor's Occupational Safety and Health Administration said OSHA investigators arrived at Loy-Lange Box Co. not long after the blast Monday morning.
