Fire consumed a trailer and scorched the side of a building when a chemical reaction sparked a blaze Wednesday night. No injuries were reported, and the building took no structural damage, according to Waterloo Fire Rescue. The fire broke out shortly 6 p.m. when workers at Kinzler Construction Services on Geraldine Road were disposing of different types of old expanding insulation foam, said Battalion Chief Mike Moore. When the different foams mixed, it created a chemical reaction that generated heat and ignited the 20-foot tandem axel trailer about 10 feet from the building, he said.
The building had minor exterior damage, and firefighters removed light smoke from inside, he said.
