You should also place a sensor in the room above the garage. At least 15 feet away from gas-burning appliances, like fireplaces or stoves. (These items already put off trace amounts of CO and could cause a false alarm.)
In a room with the fuel burning appliance: Alarms should be sited on the ceiling. Should be fitted between 1m–3m from all potential sources of Carbon Monoxide.
Eventually, if there is too much, the smoke will come through the stove's air vents and back into the room. And, bingo, it sets off your Carbon Monoxide Alarm.
A carbon monoxide detector should not be placed within fifteen feet of heating or cooking appliances or in or near very humid areas such as bathrooms.
The physical properties of carbon monoxide (CO) and the detectors themselves make positioning critical for your protection. CO is lighter than air and as it rises, it accumulates near ceilings. Detectors need to be placed higher on the walls or on the ceiling, but not so high that they're easy to ignore.
Carbon monoxide is lighter than air. It also rises with warm air, so the United States Environmental Protection Agency (EPA) recommends placing a carbon monoxide detector on a wall about five feet above the floor or about eye level. You can put them on the ceiling, too.
CO2 levels rise and fall regularly indoors. There are many factors that affect CO2 levels including ventilation, amount of people, and length of time in an enclosed space.
If you are installing only one carbon monoxide detector, the Consumer Product Safety Commission (CPSC) recommends it be located near the sleeping area, where it can wake you if you are asleep. Additional detectors on every level and in every bedroom of a home provide extra protection against carbon monoxide poisoning.
Not only does this keep your home safe, but it is also a legal requirement in many areas. According to the National Fire Protection Association (NFPA), smoke detectors must be placed near appliances and fireplaces at a distance of no less than 10 feet and no more than 20 feet.
Any of the following could be a sign of a carbon monoxide leak: Floppy yellow or orange flame on your gas hob or oven, rather than a crisp blue flame. Dark, sooty staining on or around gas appliances. Pilot lights that frequently blow out.
Don't shut off the air vents completely but close them right down as this will limit the amount of air that gets into the chamber so the fire will slowly die out. Once the embers in the fire start to go orange then you then it will start to die and you can sleep without worrying.
Install a stovepipe damper (butter-fly damper) in the stovepipe. Use less primary air into the stove. closed and the primary air control in the fully open position pass an incense stick, cigarette, or smoke pencil along all the stove's seams. If the smoke is drawn into the stove, then a leak is present.
Carbon monoxide (CO) and combination alarms should be mounted in or near bedrooms and living areas, no closer than 20cm from the ceiling. If mounting on a ceiling please make sure it is at least 20cm away from the wall.
Levels near properly adjusted gas stoves are often 5 to 15 ppm and those near poorly adjusted stoves may be 30 ppm or higher. It is most important to be sure combustion equipment is maintained and properly adjusted.
Keep units at least 20 feet (6 meters) away from common sources of combustion particles. In small homes, where 20-foot distance is not possible, place the alarm as far away from fuel-burning sources as possible.
At a minimum, though, you want to ensure you have a carbon monoxide detector at every level of your home – including your basement. They should also be placed near each bedroom and near the entrance to the garage.
A carbon monoxide alarm should be installed on every floor of a home, including the basement and near sleeping areas. It should also be installed near or over an attached garage at least 5 feet off the floor or on the ceiling.
Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor.
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.
According to carbon monoxide experts, carbon monoxide alarms should be located outside of each separate sleeping area in the immediate vicinity of the bedrooms, and each alarm should be installed on the wall, ceiling or other location as specified by the alarm's instruction manual.
The alarm should be at a horizontal distance of between 1 m and 3 m from the potential source. If there is a partition in a room, the alarm should be located on the same side of the partition as the potential source. Carbon monoxide alarms in rooms with sloped ceilings should be located at the high side of the room.
Use a CO2 Indoor Air Quality Monitor
An indoor air quality monitor that measures CO2 levels can be used as an "early warning system" for poor indoor air quality. A CO2 Monitor like the TIM10 Indoor Air Quality Monitor can be placed in an office, on a school desk, nightstand, or in a central area of the home.
No. They do not remove carbon dioxide (CO2). Almost all air purifiers are designed to capture some combination of particles and toxic gasses, but CO2 can't be captured by the same filters that capture other gaseous air pollution. Only ventilation removes CO2.
