How can carbon monoxide build up in a home? The most common causes of carbon monoxide building up are incorrectly installed or poorly maintained or ventilated appliances – like stoves and hot water heaters. Poorly ventilated fireplaces and other gas- or wood-burning appliances can also pose danger.
Even with the doors and windows open, any of these activities can trigger carbon monoxide detectors. Using a grill inside the garage or near open doors and windows–Not only is barbecuing among the most common CO-producing activities, but it can also be a fire hazard when done too close to your home.
Gas stoves. Generators and other gasoline-powered equipment. Automobile exhaust from attached garages.
One of the most common sources of exposure in the home is the gas or kerosene-powered heater. Gas-powered water heaters, stoves, and furnaces may also produce carbon monoxide.
The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. CO symptoms are often described as “flu-like.” If you breathe in a lot of CO, it can make you pass out or kill you.
Blocked Chimneys or Flues: Blocked or poorly maintained chimneys or flues can cause CO to back up into the home. Smoking: Tobacco smoke contains CO, though typically at lower levels than other sources. Barbecues: Using charcoal or gas barbecues indoors or in poorly ventilated areas can produce CO.
The greatest sources of CO to outdoor air are cars, trucks and other vehicles or machinery that burn fossil fuels. A variety of items in your home such as unvented kerosene and gas space heaters, leaking chimneys and furnaces, and gas stoves also release CO and can affect air quality indoors.
If you experience symptoms that you think could be from CO poisoning: DO GET FRESH AIR IMMEDIATELY. Open doors and windows, turn off combustion appliances and leave the house.
My carbon monoxide alarm is sounding. What should I do? Call 911 and report what is happening. Immediately leave your residence and wait for the fire department to arrive.
Two Common Causes Of False Readings: You have a cigarette smoker in the home. Cigarettes give off carbon monoxide. Artificial components, such as lighted incense or air fresheners, can trick your detectors with low levels of CO emitted into the air.
Studies have shown that ventilation rates in bedrooms often result in higher levels of CO2 that suggest poor air quality and insufficient ventilation rates [[16], [17], [18], [19], [20], [21]].
False or nuisance alarms are when your smoke detector or CO alarm goes off, but there is no presence of smoke or carbon monoxide in your home. However, if your smoke or carbon monoxide detector sounds indicating an emergency and you are not certain it is a nuisance alarm, evacuate the home and call 9-1-1.
The potential sources of carbon monoxide in the house include: Poorly functioning heating systems, water heaters, and fuel-burning devices with no vents (for example, kerosene heaters, charcoal grills, camping stoves, and gasoline-powered electrical generators)
The best way to alert you and your family to unsafe levels of CO is to install a carbon monoxide detector. It works like a smoke alarm, sampling the air in your home and creating a loud alarm when levels of the gas are detected. It's important to evacuate your home immediately when your CO alarm sounds.
It comes from the incomplete combustion of fuels with carbon, such as oil, coal, wood, gasoline and natural gas. Vehicle emissions account for the largest source. Breathing air with high concentrations of CO can result in multiple health effects. Since 1971, EPA has maintained two standards for carbon monoxide.
It is possible to have a carbon monoxide detector going off without any danger present. If you suspect that this is the case, it's important not to ignore it. This could be due to a faulty device, old batteries, or just dust buildup in the unit itself.
There are a number of potential sources of CO indoors, including gas stoves, malfunctioning or improperly vented gas appliances (i.e., water heaters, furnaces, clothes dryers), space heaters, fireplaces, tobacco smoke, and car or truck exhaust that enters from attached garages.
Even if your home is all electric, it's still recommended that you install carbon monoxide detectors, as CO can seep inside the home from an attached garage or from outside. Texas updated its building codes in 2021 to require all homes built in or after 2022 to install carbon monoxide detectors.
Some municipal fire departments and utility companies will come to your home and check for carbon monoxide for free or at reduced rates. The main tool used in these tests is an electronic portable toxic multi-gas monitor.
