To stop the sound: Press and hold the test/silence button for 5 seconds to reset the alarm. A light will keep flashing to indicate CO levels are still high.

The test/silence button might also be called test/mute, mute, reset, or a combination of those terms. Consult your user manual for specifics.

To stop the sound: Remove the old battery and wait 30 seconds to put in a new one. Match the positive end of the battery with the positive terminal.

To stop the sound: Make sure the alarm is plugged all the way in or that any wire connections are secure and unbroken. Try disconnecting and reconnecting the alarm or wrapping frayed wires with electrical tape. Wipe the air filter with a damp cloth, but don’t get the alarm wet. Sometimes, a clogged filter can trigger the alarm as well.

Do a headcount to make sure everyone is accounted for and away from the potential CO leak. Remember that carbon monoxide is odorless and colorless. Always evacuate regardless of whether you observe a direct threat or not.

If you can’t exit the building, then go ahead and open as many doors and windows as you can to increase fresh air circulation. Carbon monoxide is about the same density as air, so it can mix and travel throughout your home easily.

Once they locate the leak, they will turn off the appliance causing it and ventilate your home with high-powered fans. Once the crew finishes their work, they’ll conduct a final test to make sure your home is safe to re-enter. Do not try to re-enter your home until a professional has tested the air and said it’s safe to go back inside.

Common symptoms include:[15] X Trustworthy Source Mayo Clinic Educational website from one of the world’s leading hospitals Go to source Dull headache Weakness Dizziness Nausea or vomiting Shortness of breath Confusion Blurred vision Loss of consciousness Poisoning happens when carbon monoxide builds up in your bloodstream and starts to replace the oxygen in your red blood cells.

If necessary, you may have to replace a faulty appliance to avoid future leaks. Emergency 911 crews will turn off the original source of CO, but will not repair it.

Do this test to check the batteries and circuitry in the alarm. To test the CO sensor, purchase CO detector spray and follow the instructions on the packaging. {“smallUrl”:“https://www. wikihow. com/images/thumb/b/b3/Turn-Off-Carbon-Monoxide-Alarm-Step-10Bullet2. jpg/v4-460px-Turn-Off-Carbon-Monoxide-Alarm-Step-10Bullet2. jpg”,“bigUrl”:"/images/thumb/b/b3/Turn-Off-Carbon-Monoxide-Alarm-Step-10Bullet2. jpg/v4-728px-Turn-Off-Carbon-Monoxide-Alarm-Step-10Bullet2. jpg",“smallWidth”:460,“smallHeight”:345,“bigWidth”:728,“bigHeight”:546,“licensing”:"<div class="mw-parser-output">
