What is a potential health risk associated with exposure to carbon monoxide?

Fainting or dizziness is a significant health risk associated with exposure to carbon monoxide because this gas interferes with the body's ability to transport oxygen. Carbon monoxide binds to hemoglobin in the blood much more effectively than oxygen does, leading to reduced oxygen delivery to vital organs and tissues. When oxygen levels decrease, it can result in symptoms like dizziness, confusion, headaches, and even fainting. Serious exposure can lead to loss of consciousness and can be fatal.

Other options, while they may relate to other types of exposures, do not directly connect to the effects of carbon monoxide. For example, burns typically result from heat or fire, skin irritation is more relevant to direct contact with certain chemicals, and nausea from fumes does not encapsulate the specific dangers posed by carbon monoxide as effectively as dizziness or fainting.
