- What is an odorless, colorless gas that can poison us?
- Combustion appliances burn fuel such as natural gas, propane or wood to generate energy. Their bi-products include carbon monoxide and
nitrogen dioxide, which are colorless, odorless gases.
- Combustion gases impede the flow of oxygen through your body.
- Lower levels create headaches, dizziness, weakness, confusion and fatigue. High levels can cause unconsciousness and death.
If appliances are not vented properly to the outdoors properly, they can be releasing carbon monoxide into the home. In early 2013, 3 people who stayed at a Best Western hotel in Boone, NC were killed by carbon monoxide poisoning. The first was an elderly couple who were found dead in their room after spending the night. A month later a mother and her 11 yr old son stayed in the same room. The mother was knocked unconscious and her son was killed. It turns out, water heater from the swimming pool had an exhaust pipe that was severely corroded and was spilling lethal levels of carbon monoxide into the room on both occasions. There wasn’t a CO detector in the room. Unvented space heaters: Remove the heater completely from your home Or: Open a window slightly or use an exhaust fan when you are using the heater. Wood stoves: Make sure the stove doors are tight fitting. Follow the maker’s instructions for starting, burning, and putting out the fire. Check for red hot cracks and holes in the stove New EPA rated woodstoves are 50% more efficient than older stoves. Decrease pollution (indoor & outdoor ) by 70%. Fireplaces: Always open the chimney flue before you build a fire. Have your chimney cleaned once a year to avoid creosote build-up Furnaces: Change furnace filter several times during the winter Corrosion shows incomplete combustion and presence of combustion gases – could mean a cracked heat exchanger in the furnace Have a professional inspect if you think their might be a problem Water Heaters: Direct vented appliances like furnaces, water heaters, dryers – have their own combustion air from the outside – meaning they’re not using up
- xygen from inside the house which we also need to breathe. Make sure these appliances are getting enough air.
Back drafting – combustion gases spilling into home – caused by a venting issue or depressurization by other appliances Flame rollout – caused by appliance not getting proper oxygen levels for combustion or a venting issue Kitchen Stoves:
- Make sure your exhaust fan is vented to the outdoors.
- If you have an exhaust fan in the kitchen, use it when you cook.
- Never use the stove to keep you warm or heat your house.
Cars & Trucks: Never warm up a vehicle inside the garage. Warming up your car or truck in the garage on a cold day for just a couple minutes (even with the garage door open) can make enough CO to make you sick, and can leak into the home.
