COLUMBIA, Mo. (KMOX)
-- Research has resumed after a University of Missouri biochemistry lab explosion injuring four people Monday.
University officials say Schweitzer Hall has been declared structurally sound and safe. Students and staff are continuing their studies in other parts of the building.
A hydrogen gas explosion blew out the windows and melted blinds in the lab around 2 p.m.
The four injured, include a graduate student, a research scientist and two post-doctoral fellows. One was admitted to University Hospital and is listed in “good” condition. Three others were treated at the hospital and released.
The explosion "is believed to have been caused by a spontaneous combustion of gases including hydrogen and nitrogen that were being used in a research experiment,” according to university officials.
An investigation is underway to determine if any additional actions are necessary to prevent this accident from happening in the future.
The biochemistry lab is expected to be completely rebuilt.
