How can we control carbon monoxide poisoning?

Carbon monoxide poisoning can be controlled in the following ways :

1. By switching over from internal combustion engines to electrically powered cars.
2. Many pollution control devices are now installed in cars. Most of these devices help reduce pollution by burning gasoline completely. Complete combustion of gasoline produces only carbon dioxide and water vapour.
   2C₈H₁₈ +25O₂ ⟶ 16CO₂ + 18H₂O
3. By using substitute fuels for gasoline: Natural gas in both compressed (CNG) and liquefied forms (LNG) is now increasingly being used as fuel. Alcohols are other feasible substitutes.
4. By using catalytic converters:
   Carbon monoxide changes to carbon dioxide in the presence of finely divided platinum as a catalyst.
   $2\text{CO} \xrightarrow[\text{[O]}]{\text{Pt}} \text{CO}$2 + \text{H}2\text{O}
