Heavy condensation on the windows (found in the room with your furnace) Yellow or brown soot-like stains found around your furnace. A yellow pilot light (instead of a blue flame) Stuffy indoor air.
Signs of a Furnace Carbon Monoxide Leak
These signs may include frequent pilot light blow-outs, soot accumulation in the fireplaces, smears of yellow/brown stains near appliances, duller than normal flames from their fires as well as noticeable smells like stale air and burning.
Key points about carbon monoxide poisoning
A common source is unvented space heaters. Symptoms of CO poisoning include headache, dizziness, weakness, nausea and vomiting, rapid heartbeat, shortness of breath, seizures, chest pain, disorientation, and loss of consciousness.
One must remember that a furnace that is not running cannot generate carbon monoxide. This does not mean, however, that your home would be safe from exposure to CO anytime your furnace is turned off. The HVAC system, when it's not running, could distribute carbon monoxide if it is introduced into the system elsewhere.
Carbon monoxide can become a problem if your furnace develops cracks in the heat exchanger. When heat exchangers rust, they become brittle. As they heat up and expand, cracks can start forming in the rusty metal, which allow carbon monoxide to leak through.
According to the CDC, carbon monoxide is a silent killer that takes hundreds of lives per year. Unfortunately, you cannot tell just by looking at your furnace whether it is leaking carbon monoxide. You need a carbon monoxide detector or other special equipment to test the levels yourself.
Small carbon monoxide leaks can fill every room in your house with poisonous gas within eight hours. Severe leaks can cause this problem in just five minutes. The EPA states that exposure to concentrations of nine ppm or more for eight hours is enough to produce harmful health effects for at-risk individuals.
Maintain appliances and equipment in good order. Have a certified heating and ventilation technician check your furnace for proper ventilation and exhaust. Install carbon monoxide monitors and regularly test the air in areas where carbon monoxide is generated. Check monitors monthly for proper function.
Your boiler won't be able to produce carbon monoxide when it's switched off because it isn't burning any fuel. However, if you think you may have a carbon monoxide leak, you should switch off your gas supply at the mains.
If you experience symptoms that you think could be from CO poisoning: DO GET FRESH AIR IMMEDIATELY. Open doors and windows, turn off combustion appliances and leave the house.
Go to the Home app on your iPhone or iPad. , then tap Home Settings. Tap Safety & Security. Tap Sound Recognition, then turn on Smoke & CO Alarm.
How to test your carbon monoxide detectors to ensure they are working properly? To test your carbon monoxide detectors, press and hold the test button on the alarm. The detector will sound 4 beeps, a pause, then 4 beeps for 5-6 seconds. Refer to the user manual for your specific model.
If your boiler is switched off at the mains, your boiler will not be burning fuel and therefore no waste carbon monoxide gas will be produced.
The soot stain can have a black, brown or even yellow color. Smell: While carbon monoxide doesn't emit odor, it may get accompanied by other exhaust gases that produce an odor. A yellow burner flame: The pilot flame may produce an unusual yellow flame instead of the normal blue one.
CO is primarily produced by the improper operation or ventilation of appliances such as furnaces, water heaters, ovens, fireplaces, fuel space heaters, generators, and charcoal grills that are fueled by oil, propane, natural gas, wood, kerosene, gasoline, and diesel.
If anyone has flu-like symptoms, contact 911 and get outside for fresh air. The types of sounds and beeps the detector makes are important. Alarms that are continuously going off with a high-pitched sound mean there is a carbon monoxide leak. Contact your emergency service provider immediately.
My carbon monoxide alarm is sounding. What should I do? Call 911 and report what is happening. Immediately leave your residence and wait for the fire department to arrive.
If you think you might have carbon monoxide poisoning: stop using appliances you think might be making carbon monoxide (such as a boiler, cooker or heater) if you can. open any windows and doors to let fresh air in.
Any of the following could be a sign of a carbon monoxide leak: Floppy yellow or orange flame on your gas hob or oven, rather than a crisp blue flame. Dark, sooty staining on or around gas appliances. Pilot lights that frequently blow out.
Carbon monoxide, commonly known as CO, is an odorless, colorless, and non-irritating gas. No pet can identify the gas because CO lacks any scent whatsoever. Exposure can lead to carbon monoxide poisoning in both humans and pets.
