Carbon monoxide leaks are caused by the incomplete combustion of fuel in any carbon-based appliance, including gas or oil furnaces, water heaters, stoves, ovens, dryers, and fireplaces. Malfunctioning parts, cracked heat exchangers, blocked vents, or poor indoor ventilation cause the gas to dangerously accumulate.
Carbon monoxide (CO) is a toxic, colorless, and odorless gas produced whenever fuel is burned. Any household appliance or machine that uses gas, oil, kerosene, wood, or charcoal can produce dangerous levels of CO if it is faulty, poorly maintained, or lacks proper ventilation.
Risk factors for carbon monoxide poisoning include the use of fuel-burning appliances in enclosed or poorly ventilated spaces, occupational exposures, and increased incidence during colder months due to indoor heating.
DO GET FRESH AIR IMMEDIATELY. Open doors and windows, turn off combustion appliances and leave the house.
Two common warning signs of carbon monoxide (CO) poisoning are dizziness and a dull, throbbing headache.
The time it takes to realize carbon monoxide (CO) poisoning is occurring varies significantly based on the concentration of the gas in the environment and an individual's health. Because carbon monoxide is colorless, odorless, and tasteless, it is often called a "silent killer," and people may not realize they are being exposed until symptoms become serious.
Symptoms of Carbon Monoxide Poisoning
Low levels of CO poisoning can be confused with flu symptoms, food poisoning or other illnesses and can have a long-term health risk if left uncorrected.
Because carbon monoxide (CO) is a colorless, tasteless, and odorless gas, it is impossible to detect with human senses. The most reliable way to know if it is present in your house is by installing a CO alarm on every level of your home.
Carbon monoxide (CO) is flushed out of the body by breathing oxygen, which forces the CO off the hemoglobin in your blood. The most effective ways are immediate fresh air, high-flow 100% oxygen via a mask, or hyperbaric oxygen therapy, with treatments reducing the body's CO half-life from 4–6 hours to under 30 minutes.
Yes, opening windows and doors helps dilute carbon monoxide (CO) by letting fresh air in. However, ventilation is only a temporary measure. If your CO alarm is sounding or you suspect a leak, the priority is to shut off the source, evacuate, and call 911.
Because carbon monoxide (CO) is a colorless, tasteless, and odorless gas, it is impossible to detect with human senses. The only reliable way to know if it is in your air is by using a certified Carbon Monoxide Detector.
The greatest sources of CO to outdoor air are cars, trucks and other vehicles or machinery that burn fossil fuels. A variety of items in your home such as unvented kerosene and gas space heaters, leaking chimneys and furnaces, and gas stoves also release CO and can affect air quality indoors.
Clearer symptoms of carbon monoxide poisoning can include:
The most common causes of carbon monoxide building up are incorrectly installed or poorly maintained or ventilated appliances – like stoves and hot water heaters.
The term "silent killer gas" almost universally refers to Carbon Monoxide (CO). It is a colorless, odorless, and tasteless gas produced by the incomplete burning of fossil fuels (like wood, coal, propane, and gasoline). It is deadly because it replaces oxygen in your bloodstream, preventing vital organs from functioning.
No, you cannot smell carbon monoxide. It is a completely colorless, odorless, and tasteless gas, which is why it is widely known as the "silent killer".
Two common warning signs of carbon monoxide (CO) poisoning are dizziness and a dull, throbbing headache.
How long carbon monoxide takes to affect you depends entirely on the concentration of the gas in the air and length of exposure. In high concentrations, severe poisoning can occur in under five minutes. In lower concentrations, it may take one to two hours to show symptoms, or even weeks for low-level exposure.
Currently, the only treatments for carbon monoxide poisoning are oxygen-based therapies, which help the body eliminate the toxic gas.
No, smartphones cannot directly detect carbon monoxide (CO) on their own because they lack the necessary specialized chemical sensors. However, you can use your phone to receive alerts from dedicated smart detectors or use third-party, phone-connected sensors to monitor CO levels.
Carbon monoxide (CO) is produced whenever fuel is burned. Any household appliance that runs on gas, oil, wood, kerosene, or coal can emit CO if it is faulty, poorly maintained, or improperly ventilated.
No, dogs cannot smell carbon monoxide (CO). Because CO is a colorless, tasteless, and completely odorless gas, a dog's incredible sense of smell cannot detect it.
Fatal poisoning
One classic sign of carbon monoxide poisoning is more often seen in the dead rather than the living – people have been described as looking red-cheeked and healthy. However, since this "cherry-red" appearance is more common in the dead, it is not considered a useful diagnostic sign in clinical medicine.
Carbon monoxide is called the silent killer. You can't see it or smell it, but it can make you very sick or even be deadly. This November, take simple steps to protect your home and family: Check your CO detectors, inspect appliances, and never use generators or fuel-burning tools indoors.
The most common route of exposure to carbon monoxide is inhalation. Because carbon monoxide is a colorless, odorless, and tasteless gas, people often breathe it in without realizing it.
