A chemical spill on the University of Wisconsin-Madison campus cleared the 12th floor of the Engineering Research Building just before 4 p.m. Friday. No one was injured.
Chemists from the 11th floor of the building met members of the Madison Fire Department when they arrived on the scene and said there was a spill of nitric acid. Officers upgraded the call to a hazardous materials call, prompting the dispatch of firefighters in full hazmat gear with several more fire and rescue vehicles sent to the scene for handling the spill.
