A malfunctioning 100kW TV transmitter used by WXFT-TV Channel 60, a Spanish-language station owned by Univision, last week set fire to the 101st floor of the Sears Tower in Chicago.
The fire was reported at 1:47 a.m. and there were no injuries. The transmitter’s components apparently broke down and caused a fire. There were not a lot of flames, but it did send a lot of smoke through the floor, Larry Langford, Chicago Fire Department spokesman, told the “Chicago Tribune.”
The 110-story Sears Tower is a landmark Chicago building. The 101st floor houses mostly transmitters that connect to rooftop antennas. There are no offices or residences on the floor.
Fire crews that responded called for an elevated alarm and five ambulances as a precaution. No evacuations were required, Langford said.
