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.

My Gram's carbon monoxide detector is going off...?
Q. She and her assistant have changed the batteries like twice...i'm about to go over there. She doesn't have a car... Any ideas what it could be?
Answer
She needs to get out of the house until she finds out for sure. Take the detector outside with them because it should turn off if there is no carbon monoxide to set it off. (just in case they think it is defective)

What to do if your Carbon Monoxide Detector goes off
What to do and who to you call when your carbon monoxide detector goes into alarm?
The manufacturer of First Alert, the leading brand of carbon monoxide detectors, recommends the following if the alarm goes off:
Turn off appliances, or other sources of combustion at once.
Immediately get fresh air into the premises by opening doors and windows.
Call a qualified technician and have the problem fixed before restarting appliances.
If anyone is experiencing symptoms of carbon monoxide poisoning: headaches, dizziness, vomiting, call the fire department and immediately move to a location that has fresh air.
Do a head count to be sure all persons are accounted for.
Do not re-enter the premises until it has been aired out and the problem corrected.
To identify the source/s of carbon monoxide, have a professional check the following :
Gas or oil furnaces are frequently the source of carbon monoxide leaks. Measure concentrations of carbon monoxide in flue gases. Check all connections to flue pipes and venting systems for cracks, gaps, rust, corrosion or debris. Check the filters and filtering systems for dirt and blockages. Check the combustion chamber and heat exchanger for cracks, holes, metal fatigue or corrosion.
Check furnace flame, burners and ignition systems. A predominately yellow, flat, lazy-looking flame in a natural gas furnace indicates fuel is not burning efficiently and is thus releasing higher than usual levels of carbon monoxide. Oil furnaces with a similar problem produce an 'oil' odor, but remember you can't smell, see or taste carbon monoxide.
Chimneys and venting systems must be carefully checked for blockages caused by debris, animal nests, cracks, holes or cave-ins. A blocked chimney or venting system can force dangerous gases back into your home.
Venting and fan systems on all fuel burning appliances must be inspected for proper installation to assure carbon monoxide is vented out rather than in. Don't forget gas water heaters, clothes dryers, space heaters or wood burning stoves.
Inspect fireplaces for blocked or bent chimneys or flues, soot and debris or holes in the chimney that could release carbon monoxide exhaust back into the home.
Stove pilot lights in a closed-up home can be a source of carbon monoxide build-up if not operating properly because they are not vented to the outside. Check to be sure they are operating properly.
Fireplace pilot lights can also produce carbon monoxide and should be checked regularly.
Never burn charcoal inside no matter how much you want to recapture summer and never use your gas stove as a heater. Keep the oven door closed and use it for cooking only.
Never leave a car running in an attached garage even if the garage door is open.
Taking time to understand the characteristics of carbon monoxide and how Underwriters Laboratories, Inc. (UL) listed carbon monoxide detectors work could save your life.
According to UL Standard 2034, home carbon monoxide detectors must sound a warning before carbon monoxide levels reach 100 parts per million over 90 minutes, 200 parts per million over 35 minutes or 400 parts per million over 15 minutes. The standard requires the alarm must sound before an average, heathy adult begins to experience symptoms of carbon monoxide poisoning. The warning provides time to evacuate the premises.
