COLUMBIA, Mo. (AP) -- The University of Missouri has reopened a campus building where four researchers were injured by a gas explosion.
School officials said Tuesday that Schweitzer Hall is structurally sound and safe for researchers to return. The 98-year-old building houses the university's biochemistry department.
Monday's hydrogen and nitrogen gas explosion injured a graduate student, a research scientist and two postdoctoral fellows. Three were treated and released Monday. The fourth remained Tuesday in good condition at University Hospital.
The third-floor laboratory where the explosion occurred will be rebuilt.
