National Carbon Monoxide Awareness Month

As we observe National Carbon Monoxide Awareness Month this November, the Delaware State Fire Marshal's Office is urging Delawareans to recognize the silent and invisible threat of carbon monoxide (CO) poisoning, which claims hundreds of lives and sickens thousands each year across the U.S.

Carbon monoxide is a toxic gas produced by fuel-burning devices like furnaces, generators, fireplaces, grills, and even vehicles. Unlike fire, CO has no color, no odor, and no taste, making it virtually undetectable without an alarm.

CO exposure can cause both short-term and long-term health consequences. High concentrations can be fatal in minutes, while lower levels over time can cause chronic health issues. Many states still do not require carbon monoxide alarms in homes, hotels, schools, or other places where people sleep or gather - leaving countless individuals unknowingly exposed.

Symptoms of CO poisoning can include:
• Headache, nausea, vomiting
• Dizziness and confusion
• Shortness of breath
• Weakness, fatigue, or blurred vision
• Sleepiness, loss of muscle control, and unconsciousness

Protect Yourself and Your Loved Ones: Carbon Monoxide Safety Tips
• Install CO alarms: in your home, garage, shop, or man cave - especially near fuel-burning appliances and sleeping areas.
• Take a portable CO alarm when traveling: most hotels are not required to have them.
• Know the sound: CO alarms beep four times in a row; fire alarms beep three times.
• Test alarms monthly, replace batteries as needed, and follow the manufacturer's replacement schedule.
• Schedule annual inspections for furnaces, chimneys, and fireplaces.
• Use generators safely - keep them at least 20 feet from any building, using extension cords if needed. Never use them inside.
• Never heat your home with a gas oven or range.
• Ventilate your garage: Don't run vehicles inside, even with the door open. Back them out of the garage.
• Keep exhaust vents clear - including your home's appliances and your car's tailpipe.
