FORT COLLINS, Colo. (CBS4)– Investigators are still trying to track down the source of the smell that forced more than a dozen middle school students to go to the hospital Friday afternoon.
Administrators evacuated Blevins Middle School on the west side of Fort Collins at 12:30 p.m.
There was an odor in the building and more than a dozen students started feeling sick to their stomachs.
Firefighters and EMS personnel evaluated and treated the students and then transported 15 students by ambulance to Poudre Valley Hospital, mostly as a precaution.
It is unknown what signs or symptoms the students were presenting to medical personnel.
Firefighters and the Poudre Fire Authority Hazardous Materials Team have been working to find the cause that was initially reported to be in a laboratory room. Crews remained at the school at 5 p.m. Friday.
