Carbon monoxide detector went off?

basketball

Its 2:30 in the morning and my carbon monoxide detector went off about 20 min ago. It was realllllllly quiet and only barely woke me up, not like the loud obnoxious noise it makes when I've tested it in the past. It sounded like an alarm clock, not really a chirping sort of noise. It only went off for about minute and then stopped and hasn't gone off since. Should I be concerned? My parents just shrugged it off and went back to sleep but I'm not so sure they should have done that...CO2 is nothing to mess around with.

Answer
I've had mine go off before and worried about it, too. If it goes off but eventually turns off, you are fine. Trust me, if that thing detects ANY CO2, it will blare the holy living hell out of itself until the CO2 is gone. Also, if there were CO2 in the air, you would be throwing up, or passing out, or at the least, very very sick. If you've been in the house for twenty minutes since it went off and you are not dead, I'm sure there is nothing in the house. However, you might want to urge your parents to have it checked out tomorrow when you all wake up. If they don't, I'm 99% certain that you'll be fine. It might just be good to check and make sure.

Why does my Carbon Monoxide detector keep going off?

We have a brand new First Alert smoke/carbon monoxide detector. One day it was going off when I came home for lunch. I called the fire dept. and they came and did a test and said my levels were normal for the basement. A few weeks ago it started going off again so I opened a window. We felt no symptoms. This morning it went off yet again.

Is my device faulty? What could be the problems. Every time it has gone off I have replaced the batteries just in case the signal meant low battery.

Answer
I would try a different unit (or even different brand) and see if the results are the same. You might even try getting separate smoke/CO detectors and try different locations. And if it goes off again, I would have the fire department come and check more than the basement (and they should use two detectors to make sure THEIR readings are accurate). There's a whole myriad of factors involved here; I wouldn't rest until I was sure I wasn't in any danger. People die from CO poisoning every day. I've found a couple of websites that might help:

My digital carbon monoxide detector went off and it read GAS. So, I called the gas company and they sent out an emergency technician. He checked my stove, oven, furnace, outside meter. Everything! He checked for gas leaks and carbon monoxide but nothing showed up. He said everything was fine. So, why did my alarm go off? I bought a new one and it hasn't went off.

Answer
Sometimes it's just due to a weak battery or even dust that builds up on the detector. Most of the time its a false alarm but alway better to be safe then sorry. I have went on many 911 calls for a co detector going off and it's usually a false alarm due to a weak battery or malfunction. Batteries should be changed at least every 6 months and the detectors cleaned. This is for both co detectors and smoke detectors. Hope this helped.

Everytime my mother cooks using the stove, the carbon monoxide detector goes off. It seems like every sunday when she cooks for a long period of time faithfully the detector goes off like an hour after the stove has been shut off. I take it down remove the battery and open the windows. about 20 minutes later i put it back up....no alarm goes off. the battery is new so that shouldnt be an issue. The only thing i am fearing is a possible gas leak. What should i do?

Answer
It could be a couple of things.
How old is the detector? They have a sensor that only lasts so long and they should be replaced every 5 years.
If your mother is cooking with gas is there an exhaust fan that removes the air to the outside of the house? If not it could be caused by the recirculation of the combustion air back into the flames.
A good flame should also be a light blue, if it is a lazy yellow flame then there isn't enough primary air (air that is mixed with the gas before combustion) if that is the case then you should ask someone who knows how to adjust it and they should also check for soot which may be evidence of flame impingement.
Gas, like electricity, it is safe if done properly but can be very dangerous if done wrong and Carbon monoxide is very dangerous and any warnings should not be ignored.
