Carbon monoxide is a colorless, odorless and toxic gas that claims over 430 lives a year. It’s a byproduct of burning carbon fuel like the natural gas in your stove and the gasoline in your car. Even small doses of carbon monoxide can cause permanent damage or death, according to safewise.com.
Carbon monoxide is deadly because it binds with your red blood cells and starves your body of oxygen after passing into your lungs.
The early symptoms of carbon monoxide poisoning are headache, nausea, vomiting, dizziness, shortness of breath and fatigue.
