Here, CO devices are to be equipped with an integral alarm that satisfies the audibility requirements of the policy, have no disconnect switch between the overcurrent device and the CO alarm where the CO alarm is powered by the electrical system serving the suite, and must be mechanically fixed at a height above the floor as recommended by the manufacturer. [...] Purpose of Research Note The purpose of this research note is to draw attention to the number of carbon monoxide poisonings and deaths in Canada, which is, to some degree, preventable through the implementation of legislation requiring all new constructions to have installed and functioning CO alarms as the current built environment does not have this requirement. [...] In light of national and provincial building codes related to the prevention of CO poisoning in Canada, this report provides statistical analyses on hospitalizations and deaths in which CO poisoning was either the main diagnosis or played a part in the final diagnosis. [...] According to the Canadian Institute for Health Information, the hospitalization counts presented in this report represent acute hospitalizations in Canada with mention of carbon monoxide anywhere in the discharge diagnosis, regardless of the most responsible diagnosis for the hospitalizations. [...] The year by year change for all CO-related hospitalizations in Canada, those in which CO poisoning was the main diagnosis and those where CO poisoning was part of a diagnosis is represented in Figure 4.
