Emergency medical services took 11 people to the hospital, one of them suffering potentially serious injuries, Dr. John Gallagher, director of Sedgwick County EMS, told a news conference.
Injuries were limited because only a skeleton crew was on duty during the holidays, said Deputy Chief Daniel Wegner of the Sedgwick County Fire Department.
The explosion in a 3-inch liquid nitrogen gas line also damaged a storage tank, causing nitrogen gas to vent out of the building, Wegner said.
News video from the scene showed what appeared to be a steam cloud billowing out of the damaged building. The gas was not harmful, Wegner said.
A second valve also ruptured, said Kate Flavin, a spokeswoman for Sedgwick County, and emergency crews vented nitrogen gas from the affected tanks before doing another search of the plant.
