On October 26, 1927, Chicago Fire Department Lieutenant Jerry Tesar of Water Tower 1 died in the line of duty while fighting a 4-11 alarm fire in a commercial building on West Randolph Street. Tesar was operating the controls of the water tower to reposition it when the metal frame of the apparatus came into contact with a charged electrical trolley line. Electricity surged through the apparatus, electrocuting Tesar and throwing him from the vehicle. Efforts to revive Tesar were unsuccessful, and he died at a local hospital. Electricity continued to surge through the water tower apparatus until a firefighter with heavy gloves was able to turn the apparatus away from the live wire.
