With the storm dumping nearly two feet on parts of the Twin Cities, the snow was accumulating on the Metrodome roof Saturday night.
“It was an extraordinar situation involving Mother Nature that the Dome’s roof couldn’t handle,” Terwilliger said.
He said normal procedures were being followed Saturday, with workers on the roof itself using steam and hot water to melt and remove snow. Also, the heat inside the Dome was turned up and hot air was pumped into the in-between layers.
“That didn’t work,” Terwilliger said.
“Then it got dangerous for personnel up on the roof and we decided for the sake of safety to take them off,” he said.
What kind of idiot uses steam and hot water to get rid of snow in an industrial environment? They should’ve used propylene glycol.
