On Thursday, Oct. 17, from approximately 9 p.m. to midnight, Fermilab and the Kane County Sheriff’s Office will conduct live-gunfire tests of Fermilab’s on-site gunfire detection system. These tests will be conducted safely, using bullet traps – no live rounds will be fired into the air or into the ground, and there will be no danger to the public or wildlife. However, the sound of gunfire may be heard in neighborhoods near Fermilab on Thursday evening.
