If your smoke or carbon monoxide alarm becomes contaminated by excessive dirt, dust or grime, and cannot be cleaned, you should replace the detector immediately. You may have placed your smoke and CO alarms in an area prone to false alarms, so relocate the detector if it sounds frequent unwanted alarms.

Can dust affect a carbon monoxide detector?

Unlike smoke alarms where dust, cooking fumes etc. can cause false alarms the same problem does not exist with CO alarms. That is because CO alarms work very differently from smoke alarms.

What can trip a carbon monoxide detector?

Things That Trigger Carbon Monoxide Detectors
  • Malfunctioning gas appliances – Any gas appliance can emit CO if it's not getting the correct gas to air ratio. ...
  • Air leaks – Ductwork leaks can pull CO into your home if you use any vented gas appliances, like a dryer, water heater or combustion furnace.

Can carbon monoxide alarm go off for no reason?

Can a carbon monoxide detector go off for no reason? In most cases, no. There is typically a reason why the CO alarm is sounding, whether it detects carbon monoxide in the air or is low on battery.

Can carbon monoxide detectors give false readings?

How can you tell if there is carbon monoxide in your house?

Why did my fire alarm randomly go off in the middle of the night?

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.

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.

What level of carbon monoxide sets off an alarm?

The CO alarm sounds if your sensor detects a buildup of carbon monoxide in your home—usually before you start sensing symptoms. With a low CO level (50 ppm), it may take up to eight hours for the alarm to go off. Higher carbon monoxide levels (over 150 ppm) can trigger an alarm within minutes.

What emits carbon monoxide in a house?

Carbon Monoxide Sources in the Home

Water heaters. Furnaces or boilers. Fireplaces, both gas and wood burning. Gas stoves and ovens.

Will opening a window help with carbon monoxide?

Opening a window will slow carbon monoxide poisoning, but it likely won't stop it. There simply isn't enough airflow through most windows to get rid of the poisonous gas, and it could take between four and eight hours for the CO to dissipate entirely.

What is the most common cause of carbon monoxide poisoning?

The most common source of CO poisoning is unvented space heaters in the home. An unvented space heater uses combustible fuel and indoor air for the heating process. It vents the gases it makes into the room, instead of outdoors.

How sensitive are home carbon monoxide detectors?

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.

Do carbon monoxide detectors detect small amounts?

Average carbon monoxide levels in homes range from 0.5 parts per million (ppm) to 30 ppm or higher, according to the Environmental Protection Agency (EPA). A low-level detector from the National Safety Institute can detect levels as low as 5 ppm.

Does carbon monoxide rise or fall in a room?

There's a myth that carbon monoxide alarms should be installed lower on the wall because carbon monoxide is heavier than air. In fact, carbon monoxide is slightly lighter than air and diffuses evenly throughout the room.

What does red light on carbon monoxide mean?

On many carbon monoxide alarms, the red light flashes to show the CO alarm is properly receiving battery power. For these alarms, when you do not see the red light flashing, change the batteries in the alarm immediately.

How do I know if my carbon monoxide detector is malfunctioning?
