The Beaver Dam Fire Department says about 200 gallons of formaldehyde leaked from a damaged container at Animart in Beaver Dam on Tuesday morning. The fire department was called at 9 a.m. to help contain the leak. By the time crews arrived, Animart had been evacuated. Fire crews say a 275-gallon tank was damaged, causing the leak. Dodge County hazmat technicians and Beaver Dam firefighters were called in to help stop the leak, and contain the formaldehyde with kitty litter. A contractor out of Chicago was also called to clean up and remove the product. No injuries were reported.
