The term "silent killer gas" almost universally refers to Carbon Monoxide (CO). It is a colorless, odorless, and tasteless gas produced by the incomplete burning of fossil fuels (like wood, coal, propane, and gasoline). It is deadly because it replaces oxygen in your bloodstream, preventing vital organs from functioning.
