Carbon monoxide is a highly toxic gas known as the silent killer. It is neither visible nor detectable by smell, and just a few breaths can pose a risk of serious health consequences or death. The only effective prevention is its timely detection using a CO detector. But how should it be placed correctly to ensure its reliability is as high as possible?
Carbon monoxide is produced by incomplete combustion of solid, gaseous, and liquid fuels. Incomplete combustion occurs when there is not enough oxygen supplied to the flame or the combustion temperature is too low. The most common cause is a fault or neglected maintenance of boilers, flue paths, and chimneys, as well as insufficient ventilation. Therefore, the risk of poisoning significantly increases during the heating season.
The first symptoms of carbon monoxide (CO) poisoning appear subtly. They include lethargy, nausea, headaches, or fatigue – symptoms that can easily be overlooked or mistaken for other health issues. However, symptoms quickly worsen, leading to unconsciousness, and in fatal poisonings, internal suffocation occurs, a state where you are breathing, but oxygen is not transferred from the lungs to the tissues.
Symptoms of carbon monoxide poisoning appear subtly but quickly
Note – carbon dioxide and carbon monoxide are two different toxic gases. Carbon dioxide is a common product of breathing and other biochemical processes and is dangerous to humans only at extremely high levels, which are practically unattainable in a typical household. In the case of carbon monoxide, however, time is against you. Every inhalation increases health risks.
Carbon monoxide poisoning in the Czech Republic annually results in several hundred hospitalizations, some of which end in death. Therefore, think about prevention, get a CO detector and place it appropriately – only then will it function correctly and ensure that the sensor reliably detects a carbon monoxide leak in time and triggers the alarm.
Carbon monoxide alarms measure the presence of this gas in the air and trigger an alarm when a threshold concentration is reached. The most reliable are detectors with an electrochemical carbon monoxide sensor, which are commonly used in households and industry. Their sensitivity is very high, but only when placed correctly.
For homes and recreational properties, we recommend reliable and high-quality Honeywell carbon monoxide detectors. They have a lifespan of up to 10 years, IP44 protection, and can be wirelessly connected to other alarm devices. For safe and reliable operation, Honeywell CO detectors are equipped with a power indicator, error indicator, and test button.
Reliable and elegant Honeywell CO detector
When installing a CO detector, you must consider not only the location of combustion appliances but also the properties of CO and the conditions in the room.
Place the CO detector 1-3 meters from each combustion appliance, such as a boiler, stove, or fireplace, and also in bedrooms and at least one on each floor. If you only had detectors near combustion appliances, the alarm might not wake you at night. However, if you connect them with detectors in bedrooms and other floors, all will trigger the alarm simultaneously and safely alert household members to the risk.
Carbon monoxide is slightly lighter than air, so it rises in the room. Place the detector about 15 cm below the ceiling or at eye level, at least 150 cm above the floor. It should not be in a corner, maintain a distance of at least 30 cm from the wall.
Measured values can also be distorted by factors such as drafts. Therefore, do not place detectors near doors, windows, and fans. Also, ensure that air can flow freely to the detector, meaning there should be no furniture, curtains, etc., between the CO source and the detector.
The electrochemical carbon monoxide sensor is sensitive and can be damaged by paint, sprays, cleaning agents, or solvents and vapors from these substances, as well as humidity and dust. It is unsuitable to place it in dusty and humid environments, such as above a stove or sink.
Detectors are also sensitive to extreme temperatures, so ensure that the installation location never drops below -10 °C or exceeds +45 °C, for example, due to direct sunlight or heating elements.
Carbon monoxide alarms for households do not require any special maintenance. You only need to wipe them from dirt, using only a dry cloth or vacuum cleaner. Never clean it with water or cleaning agents. Also, monitor the battery life and the detector itself. You can verify its functionality thanks to the power indicator and test button.
The most important preventive measure is, however, preventing the formation of CO. In addition to detecting carbon monoxide, ensure regular inspections of gas appliances, chimneys, and flue paths. Think about adequate ventilation, especially in winter months.
