Change battery in carbon monoxide detector still beeping

It's scary to think that an odorless, colorless, tasteless, invisible gas can kill you in your own home or office building. By learning about carbon monoxide poisoning and what to do when there might be an unhealthy dose of CO in your building, you can mitigate the risks associated with this silent killer. 

Carbon monoxide poisoning kills about 170 people in the United States every year. CO poisoning is more common in the winter months when windows are closed and heaters, fireplaces, and furnaces are in use. These deaths are 100% preventable. It starts by having carbon monoxide detectors installed in residential and commercial buildings. The second part of the equation is making people aware of what to do when the carbon monoxide alarm is going off.

So you've taken the legal and safety precautions and installed smoke and CO detectors. But what do you do when your detector starts beeping? Below are the steps you should follow immediately:

1. Get out of the building if you or anyone else are experiencing symptoms 

This is the most important step. Take a look at the list of common symptoms to learn what to look out for. 

Symptoms of Carbon Monoxide Poisoning

  • Fatigue and drowsiness
  • Headaches
  • Impaired judgement
  • Shortness of breath
  • Confusion
  • Low blood pressure
  • Rapid heartbeat
  • Chest Pain
  • Nausea and vomiting
  • High levels of poisoning can lead to loss of consciousness and muscular coordination, and ultimately, death. 

Note that pets typically become poisoned by carbon monoxide in the building before people do. They may become very weak or unresponsive, so be aware of this when checking for symptoms or exiting the building.

When your carbon monoxide detector is beeping, acting quickly is key. The more of the deadly gas you breathe in, the more likely you are to face serious health consequences. This is because the poisonous gas replaces the oxygen in your blood, which can result in long-term brain damage, organ damage, heart damage, and death. 

It's not uncommon for people to think they have symptoms of the flu, when in fact their life is in danger. At the end of the day, it's always better to be safe by seeking fresh air if your detector is going off. Remember that breathing in CO gas can affect people differently, and once you are unconscious, there is little chance of getting out unharmed.

2. Check Your CO Detector 

Many people have smoke alarms that also function as carbon monoxide detectors. Make sure you know what kind you have. The significance of different beeping might mean different things for different types of detectors. If your detector is low on battery, you will likely hear a short chirp every minute. 

To warn of dangerous CO levels, most detectors will beep 4 or 5 times in a row about every 4 seconds. Do not mistake dangerous levels of poisonous gas for a detector with low battery! Even if no one in the building is experiencing symptoms yet, if there's a chance your detector is signaling carbon monoxide, get everyone outside to fresh air.  

3. Call Emergency Services

As soon as you are outside the building, call the closest emergency service (911) or your local fire department. Check that your family members and any visitors have made it out of the building as well. If you notice someone might be missing, do not re-enter the building. You can let emergency services know who you think may still be inside. 

It's always a good idea to have an escape plan in place for carbon monoxide or fire emergencies. This will help everyone in the building be aware of what to do and where to meet when there is an emergency. 

4. Get a Carbon Monoxide Inspection

After a carbon monoxide emergency in your building, it's imperative that you have a professional pinpoint, repair, and if necessary, replace, the source of the CO leak. Carbon monoxide can leak from different ventilation, cooking, or heating appliances and sources such as:

  • chimneys and furnace systems
  • fireplaces
  • wood burning stoves
  • cigarette smoke
  • generators
  • central heating systems
  • boilers
  • gas ranges

When there is a carbon monoxide leak, it is typically because the appliance is damaged, installed improperly, or is being used incorrectly. CO poisoning is more common in the winter because people keep their windows closed in the colder months, and are more likely to use heating appliances. For instance, if a chimney becomes blocked, the fumes enter the home instead of getting released outside. It's the same dangerous effect that an idling car in a closed garage has. 

5. Frequently Test Your Carbon Monoxide Detectors 

Even if you had a false alarm, it's important to test your detectors regularly. For detectors that are plugged into an outlet, you should test them once a month. If your carbon monoxide detectors are battery operated, change the batteries at least once a year.

By rule of thumb, carbon monoxide detectors typically last 5-7 years before they should be replaced. Manufacturers highly recommend 5 years.

Carbon monoxide poisoning is not a topic to be taken lightly. Ensure that your tenants, family members, and friends are aware of the risks of carbon monoxide poisoning and what to do when their detectors are beeping by sharing this post.

Why is my carbon monoxide detector chirping after I changed the battery?

End-of-life warning – This means your device has reached the maximum span of its working life. You'll know it's an end-of-life warning if you have tried replacing the battery but the consistent chirping continues. You need to replace the smoke detector as soon as possible.

How do you reset carbon monoxide detector after changing battery?

Here's how to reset your carbon monoxide detector:.
Find the Reset button. It's on the front panel, though the exact location and size of the button vary by brand and model..
Press and hold the Reset button for 5 to 10 seconds..
Release the Reset button, and listen for a beep. Some models may also flash a light..

How do I get my carbon monoxide detector to stop beeping?

To reset the alarm, the unit needs fresh air and time to burn the contamination off the sensor. Push and hold the silence button for 5 seconds to silence the alarm while contamination is being burned off the sensor. You may need to do this a number of times to give the carbon monoxide alarm enough time to reset.

Why does my smoke alarm keep going off even with a new battery?

Newer smoke alarms keep some errors in the processor. The smoke alarm must clear errors after the battery is changed, but it might continue to chirp even after you change the batteries. This usually occurs in electrical powered smoke alarms with a battery backup.
