Fargo, N.D. (Valley News Live) UPDATE: The Fargo Fire Department tells Valley News Live a boiler pipe broke, dumping 500 gallons of a Glycol-water mix.
That hot water produced lots of steam that was mistaken for smoke.
When crews arrived, they learned there was not an actual fire.
Firefighters are now working to clean up the mess.
The original call came in around 8:15 Tuesday morning for a structure fire at the hospital at 3000 32nd Ave. S.
