If you suspect a carbon monoxide (CO) leak or if your alarm sounds, immediately evacuate to fresh air, leave the building, and call 911. First responders have specialized, sensitive equipment to locate sources and assess safety.
Use 911 when there's a fire, serious injury, or other danger. Firefighters won't bill you for emergency response, so never hesitate if lives or property are at risk. Maintain alarms and detectors. Test and clean smoke/CO alarms regularly.
It is also a good idea to know the signs of a potential CO problem:
The carbon monoxide detector is a safety device that can alert homeowners of a CO leak and help them escape a potentially life-threatening situation, like carbon monoxide poisoning.
You don't have to feel weird about calling 911 if your carbon monoxide detector goes off. These are routine calls for first responders. 🚨🤳 Usually, a fire department and medical unit will respond. They'll work to locate the source of carbon monoxide, possibly ventilate the premises, and evaluate anyone who feels ill.
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.
Find the Certified AmeriSpec Inspector Near You
With more than 150 locations across North America, it's easy to find a certified AmeriSpec inspector near you to help with carbon monoxide testing and other specialty inspections.
The most common cause of carbon monoxide (CO) leaks is the improper ventilation, incorrect installation, or poor maintenance of fuel-burning appliances. When appliances like furnaces, ovens, and water heaters do not burn fuel completely or their vents are blocked, dangerous, odorless CO gas builds up indoors.
No, standard smartphones do not have built-in hardware to detect carbon monoxide (CO). Because CO is an invisible, odorless gas, you cannot use your phone's camera, microphone, or processor to sense it.
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.
One of the most common early symptoms of carbon monoxide (CO) poisoning is a headache, often described as dull or persistent. Because CO is odorless and colorless, these early signs are frequently mistaken for the flu or food poisoning.
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.
Mild carbon monoxide poisoning causes headache, nausea, dizziness, difficulty concentrating, vomiting, drowsiness, and poor coordination. Most people who develop mild carbon monoxide poisoning recover quickly when moved into fresh air.
If you think a gas appliance is leaking carbon monoxide, call the free National Gas Helpline immediately on 0800 111 999. The service is available 24 hours a day, 7 days a week. Every carbon monoxide death is preventable.
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 OSHA personal exposure limit (PEL) for CO is 50 parts per million (ppm). OSHA standards prohibit worker exposure to more than 50 parts of CO gas per million parts of air averaged during an 8-hour time period. The 8-hour PEL for CO in maritime operations is also 50 ppm.
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.
iPhones lack the internal hardware to directly sense carbon monoxide. To detect it and get alerts on your iPhone, you must use a separate smart carbon monoxide detector paired with its corresponding iOS app, or use an Apple HomePod to listen for traditional alarm sounds.
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.
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.
Clearer symptoms of carbon monoxide poisoning can include:
Carbon monoxide (CO) poisoning delayed symptoms—known as Delayed Neurological Sequelae (DNS)—can appear in up to 40% of survivors after an initial, seemingly full recovery. These symptoms typically emerge during a "lucid interval" of 2 to 40 days following the acute exposure and can include profound memory loss, behavioral changes, and movement disorders.
Two common warning signs of carbon monoxide (CO) poisoning are dizziness and a dull, throbbing headache.
Yes, the fire department can check for carbon monoxide.
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.
