Answer

Unintentional, non–fire-related CO poisoning is responsible for approximately 15,000 emergency department visits annually in the United States. In 2000-2009 the exposure site was reported as residence in 77.6% of cases and workplace in 12%. [10] The most common source of CO exposure in the home is furnaces (18.5%), followed by motor vehicles, stoves, gas lines, water heaters, and generators. [11] During 1999–2012, deaths from unintentional non–fire-related CO poisoning in the US totaled 6136, an average of 438 deaths per year. [12]

In 2016, the American Association of Poison Control Centers reported 12,239 single exposures to CO, 315 of which were intentional. Major outcomes occurred in 190 cases, and 48 deaths were reported. [13]
