CO Gas (Carbon Monoxide)

Carbon Monoxide (CO) is a colorless, odorless, and highly toxic gas produced by incomplete combustion of fuels like gasoline, natural gas, and wood.

Key Points

• Chemical formula: CO.
• Displaces oxygen in the bloodstream, leading to poisoning symptoms (headache, dizziness, nausea).
• Can be fatal in high concentrations — often called the “silent killer.”
