CARBON MONOXIDE (CO) ALARM
 

NEVER IGNORE THE CO ALARM

CO is called the “silent killer” because it is an invisible, odorless, tasteless gas produced when fossil fuels do not burn completely, or are exposed to heat (usually fire). These fuels include: wood, coal, charcoal, oil, natural gas, gasoline, kerosene, and propane. Electrical appliances typically do not produce CO.
