    Carbon Monoxide Safety

    The silent killer. How to stay safe.

    What is carbon monoxide?

    • Colorless, odorless, tasteless gas.
    • Can't see it, smell it, or taste it.
    • Produced by combustion — gas, propane, wood, charcoal.
    • Kills 400+ Americans yearly.
    • Sends 50,000+ to emergency rooms.
    • Seniors more vulnerable to poisoning.

    Symptoms of CO poisoning

    • Headache.
    • Dizziness or confusion.
    • Nausea or vomiting.
    • Shortness of breath.
    • Weakness or chest pain.
    • Often mistaken for flu.

    Detector requirements

    • Required by law in most states.
    • One on every floor of home.
    • Outside each sleeping area.
    • Replace every 5–7 years.

    • Many CO + smoke combo units available.

    Check your detectors today

    Push the test button on every smoke and CO detector right now. If they don't beep loudly, replace the batteries (or the unit if older than 7 years). $30 per detector versus your life is the easiest math you'll ever do. If you don't have CO detectors at all, buy them today on Amazon — they'll arrive tomorrow. Many seniors have died from CO poisoning that a $30 detector would have prevented.
