OTTAWA — Although it was a construction worker who overcome by carbon monoxide Monday, Ottawa Fire Chief Jeff Carner said it can be a problem for homeowners, too. Carbon monoxide is created by incomplete combustion and has affected people living in houses, he said. You should make sure your furnace is working at optimal levels and that you have working carbon monoxide detectors. During winter, the number of fires and carbon monoxide poisonings increase, he said.
