  • headache.
  • dizziness.
  • feeling sick or being sick.
  • feeling weak.
  • confusion.
  • chest and muscle pain.
  • shortness of breath.

What can trigger a carbon monoxide alarm?

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.

How do I know if my carbon monoxide detector needs a new battery?

1 beep every minute: This means that the detector has low batteries and you should replace them. 5 beeps every minute: This means your alarm has reached the end of its life and needs to be replaced with a new carbon monoxide alarm.

Fossil fuel-burning appliances may not be burning fuel completely. Check pilot lights/flames for blue color. Appearance of yellow or orange flames indicates incomplete combustion—a source of carbon monoxide.

Can a carbon monoxide detector detect gas leak?

Ultimately, no, a carbon monoxide detector cannot detect a natural gas leak. Carbon monoxide (CO) is a toxic gas created when fuel is burned in the presence of low levels of oxygen. Carbon monoxide is very different from methane and cannot be detected with the same sensor.

How do you test for carbon monoxide?

The Best Way to Test for Carbon Monoxide

Because CO is colorless, tasteless, odorless and non-irritating, the best way to detect its presence is to use an electronic combustion testing instrument.

Can you be slowly poisoned by carbon monoxide?

Carbon monoxide (CO) poisoning can become deadly in a matter of minutes. If you suspect CO poisoning, leave your home or building immediately and call 911 or go to the emergency room. If treated quickly, the effects of CO poisoning can be reversed.

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.

Does carbon monoxide make you sleepy?

Most people with a mild exposure to carbon monoxide experience headaches, fatigue, and nausea. Unfortunately, the symptoms are easily overlooked because they are often flu-like.
