Small explosion rocks UW chemistry building

MADISON (AP) -- A small explosion inside a laboratory at the University of Wisconsin-Madison chemistry building has sent one person to the hospital with non-life threatening injuries.

University of Wisconsin Police Department Sgt. Aaron Chapin says the explosion occurred around 9:30 a.m. Monday. He says one staff member was injured but his name was not being immediately released.

UW-Madison spokesman John Lucas says a lab experiment ignited and broke a glass container holding the chemicals. He says the person injured was cut by the glass.

Lucas says there was no fire and the building was not evacuated. Chapin says there were no street closures and the building remained opened except for the lab where the explosion occurred.
