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.
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.
Warning Signs of a Furnace CO Leak
If you're unsure of how to identify a carbon monoxide leak, there are several signs to keep an eye out for. These warning signs include: Heavy condensation on the windows (found in the room with your furnace) Yellow or brown soot-like stains found around your furnace.
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.
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.
To reduce carbon monoxide in your home without air purifiers or oxygen masks, ensure proper ventilation by opening windows and doors regularly to allow fresh air in. Regularly maintain and check gas appliances, heaters, and stoves. Install and maintain carbon monoxide detectors to alert you to any dangerous levels.
Install battery-powered carbon monoxide detectors throughout your home. While not as powerful as professional equipment, they can help alert you to dangerous levels of gas in your home.
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.
In most areas, the fire department does not charge to respond to carbon monoxide alarms or to check for the presence of CO in a residence. However, policies can vary depending on the jurisdiction or specific fire department. It's always a good idea to contact your local fire department for specifics on their policies.
Test Overview
The test measures the amount of hemoglobin in your blood that has bonded with carbon monoxide. Carbon monoxide can come from any source that burns fuel. Common sources are cars, fireplaces, powerboats, woodstoves, kerosene space heaters, charcoal grills, and gas appliances such as water heaters and ovens.
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.
The symptoms of exposure to low levels of carbon monoxide can be like those of food poisoning and flu. Carbon monoxide poisoning doesn't cause a high temperature. The longer you inhale the gas, the worse your symptoms will be. You may lose balance, vision and memory and even consciousness.
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.
Any furnace that burns fuel produces carbon monoxide as a byproduct. This is the same for any appliance in your home that burns fuel, such as a gas range. Therefore, if your furnace uses natural gas, propane, or oil to make heat, your furnace creates carbon monoxide. Electric furnaces do not create carbon monoxide.
Check the thermostat settings.
The furnace will not come on unless the ambient temperature drops below the setpoint. To test the furnace, temporarily set the thermostat five to ten degrees higher than you normally would to see if it comes on, then return the thermostat to its normal setting when the test is complete.
The easiest way to see if there is carbon monoxide inside your home is with a carbon monoxide detector (which also includes an alarm). In fact, many building codes require a carbon monoxide gas detector.
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.
The most common causes of carbon monoxide building up are incorrectly installed or poorly maintained or ventilated appliances – like stoves and hot water heaters. Poorly ventilated fireplaces and other gas- or wood-burning appliances can also pose danger.
