Check your carbon monoxide detectors, Ottawa fire warns after recent close calls

Ottawa Fire Services are reminding residents to check the functionality of their carbon monoxide detectors after two recent close calls at homes in Ottawa.
According to officials, in the past two weeks, firefighters have responded to a number of calls where carbon monoxide alarms were activated. In some cases, the alarms were defective and needed new batteries or replacement.
However, in two cases, the level of carbon monoxide detected in the homes was highly toxic.
