Chemical leaks in tunnels beneath Caltech library
A chemical leaked today in the tunnels beneath the Millikan Library on the campus of Caltech, and two workers were treated for possible eye irritation, authorities said.
The problem was reported about 5:30 a.m. at the college in the 1200 block of East California Boulevard, said Lisa Derderian of the Pasadena Fire Department.
About 20 construction workers and cleaning personnel were evacuated from the tunnels, which link various campus buildings, and firefighters were sent to handle the problem, Derderian said.
