What is Carbon Monoxide?
Facts and Figures
- 480 U.S. residents died between 2001 and 2003 from non-fire-related carbon-monoxide poisoning.
- Most CO exposures occur during the winter months, especially in December (including 56 deaths, and 2,157 non-fatal exposures), and in January (including 69 deaths and 2,511 non-fatal exposures). The peak time of day for CO exposure is between 6 and 10 p.m.
- Many experts believe that CO poisoning statistics understate the problem. Because the symptoms of CO poisoning mimic a range of common health ailments, it is likely that a large number of mild to mid-level exposures are never identified, diagnosed, or accounted for in any way in carbon monoxide statistics.
- Out of all reported non-fire carbon-monoxide incidents, 89% or almost nine out of 10 of them take place in a home.
Physiology of Carbon Monoxide Poisoning
When CO is inhaled, it displaces the oxygen and effectively suffocates the body. CO can poison slowly over a period of several hours, even in low concentrations. Sensitive organs, such as the brain, heart and lungs, suffer the most from a lack of oxygen.
