KAUKAUNA, WI (WTAQ) – Some firefighters in Kaukauna were called in late Sunday night to cool down some hot coal dust at the Expera mill.
The call came in around 11:50 p.m. to the mill at 600 Thilmany Road.
Employees became alarmed by warmer than normal temperatures in a bin of coal being used for boilers. The bin was 4 to 5 stories off the ground. Firefighters coated the inside of the bin with foam and about 600 gallons of water to prevent an explosion.
Mill workers reported the bin had cooled significantly by 3 a.m. Four hours later, the source of the heat was out.
