Stunned workers look on as heavy smoke billows out of Tarco Steel on Spud Lane.
It's the second time this year they've seen their building damaged.
"We sort of just got back together. In June we had almost 2 feet of water up here," says Tarco employee Joe Rowan.
Tarco Steel provides metal products and custom cutting services.
When the fire started this morning, 13 employees were inside.
Everyone evacuated safely and watched as 4 fire companies attacked the blaze.
"It's really some unusual arid smoke, you can't even breathe a small amount of it," says Deputy Fire Coordinator.
Vroman says that smoke is likely a byproduct of new insulation and steel dust.
Crews were inside installing the insulation this morning.
Now the company prepares to re-bound again.
"This close together and this time of the year it's tough, but we'll bounce back from it. I wouldn't expect to be down more than a day," says Tarco Manager Rick Simon.
Tarco will in fact open Thursday.
Simon says the fire did not damage the steel products inside.
Tarco Steel started in 1970.
In 2000 it opened a related business, Metal Fab.
Tarco built on Spud Lane in Kirkwood in 2003.
In 2005 it built a place for the Metal Fab company next door.
It was not affected by the fire.
The Tarco company employs 25 people.
