TAMPA — USF students and teachers were allowed back into a chemistry building on campus early Tuesday afternoon after authorities discovered the source of a suspicious gas smell.
A chemical that is put into gas to emit the distinct smell was being taken out of the building in an elevator, unintentionally spreading its scent on its way out, said Lt. Meg Ross of the USF Police Department.
The scent is normally added so people notice gas leaks.
Ross didn't know how much of the chemical was transported, in what container or where it was going.
About 30 people had been evacuated from the Natural and Environmental Sciences Building when someone reported the smell to police at about 11:15 a.m.
No one was injured.
