Why is carbon monoxide especially dangeruos?

Answer 1

It bonds with the haemoglobin in the red bloodcells thus reducig their capacity to carry oxygen around the bloodstream dramatically. Therefore if you breath in carbon monoxide in significant concentrations you asphyxiate and die.

Answer 2

Carbon monoxide is especially dangerous because it is a colorless, odorless gas that can be deadly when inhaled. It binds to hemoglobin in the blood more readily than oxygen, leading to a decrease in the blood's ability to carry oxygen to vital organs like the brain and heart. Prolonged exposure to high levels of carbon monoxide can result in symptoms like dizziness, confusion, and eventually death.
