A fire at County Concrete shut down the 1100 block of Menomonie Street for about four and a half hours.
No one was seriously injured as a result of the fire and it took about an hour for firefighters to contain it.
The Eau Claire Fire Department received the call of a fire at County Concrete on the 1100 block of Menomonie Street.
The fire started in a 'shop' building filled with chemicals and tanks of oxygen that -- with a fire -- can become very volatile.
"We've been dealing with oxygen and hydraulic fluids. The goal is to try and contain these," Eau Claire Fire Department Chief Bruce Fuerbringer said.
It took firefighters longer than usual to contain the fire due to the chemicals, which *not only* presented dangers to people nearby, but the firefighters as well.
"when dealing with something like this it can be very dangerous. We've been using longer lines so firefighters won't be in harms way and we can still get the water up in there," Chief Fuerbringer said.
The fire department needed four engines and multiple hydrants to put out the blaze.
Even after the road was opened, firefighters will remain on scene well into the night to check for 'hot spots.'
After smoke clears, fire investigators will look into the cause, but early indications from the fire department say it does not look suspicious.
