The Towers at Williams Square
IRVING — Three Irving firefighters were hurt battling what was originally described as a three-alarm fire at a Las Colinas high-rise office tower Sunday morning.
But the white "smoke" seen billowing from the top of the 26-story central tower in the Williams Square complex at 5215 North O'Connor Boulevard turns out to have been water vapor from a malfunctioning sprinkler system.
Two of the firefighters were hospitalized after a hose popped off a standpipe and struck them. A third firefighter was also taken away in an ambulance for treatment. Their injuries were said to be not serious.
Irving Fire Department Assistant Chief R.W. Wilson confirmed that the 7:30 a.m. incident was not a fire. He said a "deluge system" designed to extinguish fires had been triggered by a malfunctioning sensor. The water then cascaded down on the fan blades of the building's air conditioning system, which spun the water into a cloud-like vapor seen rising from the top of the tower.
It is not yet clear if the building will be open for business on Monday morning. There was nobody at work there during the incident.
The Towers at Williams Square consists of four pink granite buildings built in 1981, and is perhaps best known for the bronze sculpture of nine wild mustangs running across a "stream" in the plaza.
