Yes, a carbon monoxide (CO) detector can keep going off for several reasons, and it is a situation that should always be addressed immediately. The detector's response is usually categorized by the type of alarm or sound it emits:
Many false alarms are preventable and stem from simple issues with smoke and CO detectors, including:
It is also a good idea to know the signs of a potential CO problem:
4 beeps and a pause: This indicates there is carbon monoxide in the air, seek fresh air immediately and call 911. 1 chirp every minute: This indicates the alarms batteries are low and you should replace them. 3 chirps every minute: This indicates the alarm has encountered a malfunction and requires replacement.
In domestic properties, your CO alarm can be triggered by any fuel burning appliance such as gas cookers, boilers and ovens. All of these appliances give off small traces of CO, but the levels can rise slightly when adequate ventilation isn't provided, or the venting is blocked or clogged by dust.
Common Causes of CO Alarms Going Off
Common reasons for false CO alarms include: Low battery or sensor degradation. Dust or humidity near the sensor. Placement too close to fuel-burning appliances.
Opening windows helps the carbon monoxide quickly leave your home (as does opening doors). However, don't leave your exit path when getting out during this emergency to open as many windows as you can. Only open those that are along the way as you leave your home safely.
How long does it take to get carbon monoxide poisoning? In high concentrations of carbon monoxide, it can take fewer than five minutes to get carbon monoxide poisoning. Under lower concentrations, it can take an hour to two hours to cause poisoning.
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 detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flame-producing appliance.
Early symptoms of exposure to CO, even after only breathing it for a short time, include:
Your Nose Detects Exhaust Gases. Carbon monoxide has no odor, but several exhaust gases often accompany it when a leak occurs. Your nose might detect a burning smell, which can come from a leak out of a gas-fueled appliance.
Clearer symptoms of carbon monoxide poisoning can include:
If your carbon monoxide detector goes off--especially with a continuous alarm--it's essential to act immediately. Even if no one in your home feels sick, carbon monoxide exposure can escalate quickly and become life-threatening before symptoms appear.
The OSHA personal exposure limit (PEL) for CO is 50 parts per million (ppm). OSHA standards prohibit worker exposure to more than 50 parts of CO gas per million parts of air averaged during an 8-hour time period. The 8-hour PEL for CO in maritime operations is also 50 ppm.
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.
Significance: In some models, a series of beeps every 30 seconds may indicate that the battery is low and needs replacement. Action: Check the battery and replace it according to the manufacturer's instructions. After replacing the battery, reset the alarm and ensure it is functioning correctly.
Levels of carbon monoxide exposure range from low to dangerous: Low level: 50 PPM and less. Mid-level: Between 51 PPM and 100 PPM. High level: Greater than 101 PPM if no one is experiencing symptoms. Dangerous level: Greater than 101 PPM if someone is experiencing symptoms.
Because we all breathe out carbon dioxide, the gas tends to build up indoors, particularly when there isn't much ventilation.
If you have a mild case of CO poisoning, you'll feel better just by going outside and breathing fresh air. More severe cases may require treatment with pure oxygen or hyperbaric oxygen therapy (HBOT).
Killer. Carbon monoxide (CO) is a gas that can kill you quickly. It is called the “silent killer” because it is colorless, odorless, tasteless and non- irritating. If the early signs of CO poisoning are ignored, a person may lose consciousness and be unable to escape the danger.
The most common symptoms of carbon monoxide poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. Symptoms of carbon monoxide poisoning are often described as “flu-like.” If you breathe in a lot of carbon monoxide it can make you pass out or kill you.

5 Common Causes of False Alarms
In many cases, you can fully recover from carbon monoxide poisoning. But sometimes, it can lead to permanent brain damage or death. If you notice mild symptoms of carbon monoxide poisoning, get outside to fresh air and call 800-222-1222 to reach a poison control center.
