Without any doubt, Oxygen is the only gas a human body needs to survive. However, on the contrary, Carbon monoxide is perhaps the only gas that humans need to avoid! The highly noxious gas comes from the partial burning of wood, coal, and other carbon-containing materials. If it does not find a space to evacuate and accumulate, the consequences are very bad for human health.

The extraordinarily toxic gas, Carbon monoxide, is part of our daily lives. Therefore, many people prefer to have CO alarms in their homes or workplaces like mechanical garages, etc. Unfortunately, it is not a rarity if your CO alarm goes off or gives false alarms. If you have arrived at this article to know why your carbon monoxide alarm keeps going off, then you are spot on!

This article briefly discusses why a carbon monoxide alarm going off, or why it turns on while there is no CO accumulation in the surroundings. Moreover, we will also discuss what you can do to get rid of the issue!

Why is my carbon monoxide detector going off?

If your Carbon monoxide detector goes, understandably, it would make you panic for a while. However, we believe you must take your next step vigilantly. First of all, you have to keep in mind that there are many reasons why your CO detector goes off!

Even when there is a small amount or traces of CO in any closed space, the detector will react! Therefore, you must think about the presence of CO in your surroundings and turn off the stoves or any burning furnaces. If you are in an RV, please turn off the engine because these engines are pretty much responsible for liberating CO gas.

Next in line, sometimes, worn-out batteries may cause false alarms as well. Perhaps, there is no CO in the atmosphere, yet the malfunctioning would make you nervous!

The other times, it is not about the batteries of the CO detector, but its life that has reached an end. Accordingly to manufacturers, people can benefit from a CO detector for five years and not more than that!

What causes the carbon monoxide alarm to go off?

As mentioned earlier, there are different reasons why does a CO monoxide alarm goes off. It could be true that there is CO present in your surrounding area, be it an RV, kitchen, home, garage, etc. At times, the detector malfunctions owing to worn-out batteries. Besides, if your CO detector has got quite old, chances are it would go off on its own!

Let’s ride through all the possible causes for your CO alarm that keeps going off;

1. Carbon Monoxide’s presence in the surrounding

The first and foremost thing that would come to your mind when you see your CO detector going off is that you need to take measures because there is a trace of CO in your environment. Mostly, RVs are more prone to CO accumulation because of the constantly turned-on engine. Therefore, even small traces of CO trigger the CO detector present in an RV. Usually, very little or no CO is present in residences; however, you have to be prepared for anything!

Therefore, you must turn off all the appliances that you think may produce CO. Also, please make the area well ventilated, while in cases of RV, please leave the vehicle! Besides, you must look for the signs of CO poisoning in people around you; whether in an RV or at home, please do not ignore any symptoms of CO poisoning!

Furthermore, the maximum you can do is call an expert and get all your appliances checked so that such a thing does not happen again.

2. False alarms by CO detectors

There are several reasons why your CO detector tends to produce false alarms, which we will discuss later in the article. However, for now, you must remember that having a cheap and low-quality CO detector comes up with false alarms frequently.

In addition, closed spaces with burning appliances like stoves, heating furnaces, ovens, etc., are more prone to false alarms by CO detectors. This is because you must know that a little CO comes up whenever there is a burning process! However, if the area is open and ventilated well, the detector would never go off.

Not very often, but if there is a huge amount of petrol fumes in a closed space, that can also trigger a CO detector.

3. Your RV CO detector’s life has ended

According to most experts, even high-quality CO detectors do not last for more than five years. Therefore, another reason your CO detector in RV or at home goes off is that its life has reached an end.

However, you can still keep using the Safe T-Alert CO detector in an RV by pushing the reset button on the alarm. You can make use of the reset alarm for 30 days, but after that, you will need to replace it with the new one for sure!

What causes false CO alarms?

As mentioned earlier, false CO alarms can happen for many reasons. For example, at times, there is an accumulation of petrol fumes in a noticeable amount, which may trigger the CO detector. Similarly, small traces of CO coming from faulty home appliances like stoves, ovens, heating furnaces, etc., can also give wrong signals to the CO detector, which would consequently go off.

Many times, people charge their car’s lead-acid batteries at home, which may trigger the CO alarm. These batteries produce hydrogen gas which makes your CO detector goes off, and you might take the alarm as a real one.

Last but not least, you must not forget that many times when your CO detector’s battery turns low, it would give sounds to enlighten you! However, undeniably, these sounds may stimulate false CO alarms.

  • Your first measure consists of evacuating the closed space or RV right away along with all the people.
  • While you gather all the people before evacuating the space, you must open all the windows and doors of the area to allow the gas to escape.
