Which of the following is a common cause of carbon monoxide poisoning?

Smoke inhalation from fires is a common cause of carbon monoxide poisoning because, during a fire, carbon-based materials are burned, releasing various toxic gases, including carbon monoxide. This gas is colorless and odorless, making it particularly dangerous, as victims may not be aware they are being exposed to it until symptoms arise. Inhaling this toxic gas can quickly lead to dangerous levels in the body, impairing oxygen delivery to vital organs and leading to serious health issues or even death.

While the other options may pose their own health risks, they are not associated with carbon monoxide poisoning. Swimming pool accidents typically involve drowning or injury, allergic reactions are related to immune responses rather than toxic gas exposure, and excessive alcohol consumption leads to its own set of health problems, but it does not relate to carbon monoxide exposure. Understanding the primary sources of carbon monoxide can help in prevention and timely intervention in cases of exposure.
