What to do if carbon monoxide detector goes off and then stops?Call 911 immediately and report that the alarm has gone off. Do not assume it is safe to reenter the home when the alarm stops. When you open windows and doors, it helps diminish the amount of carbon monoxide in the air, but the source may still be producing the gas.
Why did my carbon monoxide detector go off and then stop?4 beeps and a pause: This means that there is carbon monoxide in the air and you should seek fresh air immediately and call 911. 1 beep every minute: This means that the alarm has low batteries and you should replace them. 3 beeps every minute: This means the alarm has encountered a malfunction and needs replacement.
Can a carbon monoxide detector go off falsely?Smoke and carbon monoxide (CO) detectors can false alarm for several reasons. False or nuisance alarms are when your smoke detector or CO alarm goes off, but there is no presence of smoke or carbon monoxide in your home.
What can trigger a carbon monoxide alarm?Any fuel-burning appliance that is malfunctioning or improperly installed. Furnaces, gas ranges or stoves, gas clothes dryers, water heaters, portable fuel-burning space heaters, fireplaces, generators, and wood burning stoves. Vehicles, generators, and other combustion engines running in an attached garage.
What are two warning signs of carbon monoxide poisoning?What are the symptoms of CO poisoning? The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. CO symptoms are often described as “flu-like.” If you breathe in a lot of CO it can make you pass out or kill you.
What to Do When Your Carbon Monoxide Detector Goes Off

Can anything else set off a carbon monoxide alarm?Malfunctioning water heater or furnace: Improper ventilation, excess gas flow or other malfunctions could set off your carbon monoxide detector. Obstructed chimney: If fumes can't escape, they become trapped inside. The carbon monoxide detector senses this and sounds the alarm.

Will a carbon monoxide alarm go off if there is a gas leak?CO alarms only detect the poisonous, odourless by-products from burning processes called carbon monoxide (CO). CO gas is created when flammable gas is burned without enough oxygen. CO detectors cannot detect flammable gases.
What does a carbon monoxide detector sound like when it is going off?Here's a simple guide: Smoke alarms alert you with three beeps in a row. Carbon monoxide alarms alert you with four beeps. A single chirp means the battery is low or the detector should be replaced.

- Dark and sooty staining on or around gas appliances.
- Pilot lights that frequently blow out.
- Increased condensation on windows.
- Solid fuel fires burn much slower than usual.

CO poisoning needs to be treated right away by getting outside to fresh air and calling 911.
How do you treat mild carbon monoxide exposure?Treatment of Carbon Monoxide Poisoning
For mild carbon monoxide poisoning, fresh air may be all that is needed. To treat more severe poisoning, high concentrations of oxygen are given, usually through a face mask. Oxygen hastens the disappearance of carbon monoxide from the blood and relieves symptoms.
Is poisoning by carbon monoxide is easy to diagnose?How to Recognize CO Poisoning: The symptoms and signs of carbon monoxide poisoning are variable and nonspecific. The most common symptoms of CO poisoning are headache, dizziness, weakness, nausea, vomiting, chest pain, and altered mental status.
How much carbon monoxide does it take to trigger an alarm?They are NOT required to warn of low-levels of CO. The UL standard requires detectors to alarm within 90 minutes when exposed to 100 ppm; 35 minutes when exposed to 200 ppm and 15 minutes when exposed to 400 ppm. Some detectors are more sensitive and will, when exposed for many hours, detect or alarm at lower levels.
Why did my smoke alarm go off in the middle of the night for no reason?This battery characteristic can cause a smoke alarm to enter the low battery chirp mode when air temperatures drop. Most homes are the coolest between 2 a.m. and 6 a.m. That's why the alarm may sound a low-battery chirp in the middle of the night, and then stop when the home warms up a few degrees.
Can you be slowly poisoned by carbon monoxide?The symptoms of exposure to low levels of carbon monoxide can be similar to those of food poisoning and flu. But unlike flu, carbon monoxide poisoning doesn't cause a high temperature (fever). The symptoms can gradually get worse with long periods of exposure to carbon monoxide, leading to a delay in diagnosis.
