Carbon monoxide is a dangerous gas that you cannot see or taste because it has no odor or color. It blocks your body from carrying the oxygen you need to your brain. Regular exposure can cause a variety of symptoms as well as death.
At CornerStone Protection, we believe in keeping your family safe through proper carbon monoxide detector placement. Protect your property from carbon monoxide (CO) poisoning by learning how we can help and then reaching out.
Why Your Home Needs Carbon Monoxide Detectors
Common sources of carbon monoxide in your home include your furnace and any gas-powered appliances. As you live in Kentucky, you probably only use your furnace during the late fall through the early spring. It can easily develop a leak that exposes your family to carbon monoxide.
With the right carbon monoxide detector placement, you can keep your loved ones protected. These detectors pick up gas coming from a generator or a fireplace, along with any fumes your car produces. The only way to tell if you have a carbon monoxide leak is with a functional detector.

The Right Placement for the Ultimate Protection
Every level of the home: Install at least one CO detector on each floor, including finished basements and livable attics, to ensure all areas are protected.
Near bedrooms: Install a carbon monoxide detector in hallways or common areas just outside sleeping spaces. This placement ensures that the alarm can wake everyone if carbon monoxide levels rise during the night. Additionally, you should place a detector in your bedroom or near any room where you or a loved one sleeps. If a bedroom contains a gas appliance or furnace, it is also important to install a detector inside that room.
Close to attached garages: Car exhaust and gas-powered tools are common CO sources. We recommend placing one in your garage if you have an attached garage or if it is located near your home. You should also put one in your bedroom or close to any room where you or a loved one sleeps.
Close to fuel-burning appliances: Keep detectors within about 10–15 feet of furnaces, stoves, fireplaces, or water heaters. This is near enough to detect leaks, but far enough to avoid false alarms when the appliances start up.
How Many Carbon Monoxide Detectors Do I Need?
The number of detectors you need depends on the size of your Kentucky home. We generally recommend at least one per story or level. This includes the basement as the gas rises. When you schedule a carbon monoxide detector placement with us, we usually recommend at least one per floor. You may need more than one carbon monoxide detector based on the square footage of each story.

Common Location Mistakes – Places You Should Not Install Carbon Monoxide Detectors
To make sure your carbon monoxide detectors work properly, it’s just as important to know where not to put them as it is to know the right spots. Incorrect placement can cause false alarms or prevent the detector from sensing dangerous CO levels. Here are common mistakes to avoid:
Too close to fuel-burning appliances: Don’t mount detectors directly next to furnaces, fireplaces, stoves, or water heaters. These appliances can release small bursts of CO during normal operation, which may trigger unnecessary alarms. Instead, keep the detector about 10–15 feet away.
In damp or humid rooms: Spaces like bathrooms and laundry rooms produce moisture that can interfere with the detector’s sensors, leading to unreliable readings.
In extreme heat, cold, or direct sunlight: Detectors are designed to work within a certain temperature range (usually between -10°C and 40°C). Placing them near windows, heaters, or in direct sunlight can shorten their lifespan or cause malfunctions.
In dead air zones or near vents: Avoid corners, closets, or areas near heating and cooling vents. Airflow in these spots can either trap carbon monoxide or blow it away before the detector senses it.
Inside garages, kitchens, or furnace rooms: These spaces often contain dust, smoke, or other gases that can interfere with the sensor and cause false alerts. Place detectors just outside these rooms instead.
Next to doors or drafty windows: Constant airflow from outside can dilute CO levels and prevent accurate detection.
Too low to the ground: Carbon monoxide mixes with indoor air and is best detected at breathing height, not near the floor. Install detectors on a wall or ceiling at head level or higher.
Within reach of children or pets: Mount detectors high enough so they can’t be tampered with, knocked down, or damaged.
By avoiding these locations, you’ll improve the accuracy of your CO detectors and ensure your family gets the earliest warning if carbon monoxide becomes a threat.
Carbon Monoxide Levels Measured and Symptoms
Knowing what a CO detector is isn’t the only thing you need to know. It’s equally important to understand safe levels and the symptoms of exposure. Adding a CO detection system to your existing home automation system is a great way to know when levels become dangerous.
0–35 ppm: Indoor air levels are considered normal and safe. At this level, everyone should feel secure.
50–200 ppm: Mild symptoms such as headaches, dizziness, or fatigue after a few hours.
200–400 ppm: Stronger headaches, nausea, and confusion may occur within 1–2 hours.
800 ppm and above: Dizziness, nausea, and unconsciousness can occur within 45 minutes. Death is possible within 2–3 hours.
1,500 ppm or more: Severe risk of death within one hour of exposure.
Carbon monoxide is dangerous because symptoms can feel like the flu and build gradually. Without a detector, most people don’t realize they’re being poisoned until it’s too late.

What Should You Do if You Hear an Alarm?
The most important of all carbon monoxide safety tips is knowing what to do when you hear the alarm. Different models sound the alarm at different levels, but this is always a warning sign. As exposure to CO can lead to death, hearing your home’s CO detector alarm is a clear sign to evacuate the house.
Make sure everyone in your home gets outside and into the fresh air. Call 911 on your cell phone or ask a neighbor to call for you. Let them know you think you have a gas leak and are in danger. It’s also a smart idea to call your gas company and have someone come out to turn off your gas. We offer systems that work with home security systems to give you more security. Call us today to see how we can install a system and help you choose the right carbon monoxide detector placement.
Testing and Maintaining
Testing and routine maintenance help with CO poisoning prevention. Every month, test the detector to make sure it works as it should. Most detectors have a built-in testing button.
If you have a standard detector that runs off battery power, replace the battery every six months. You can also give it a light cleaning to remove any dust buildup. We also recommend our clients replace their units at least once every seven years, though some, like a carbon monoxide detector with a camera, may last longer.

Tips to Keep Your Home Safe from Carbon Monoxide
Because many everyday appliances can produce carbon monoxide, it’s important to keep them in good condition and use them safely. A few simple habits can go a long way in preventing dangerous CO buildup inside your home.
What to Do:
Service heating systems and fuel-burning appliances yearly: Have your furnace, water heater, and any gas, oil, or coal-burning appliances checked by a professional once a year.
Inspect chimneys and vents: Make sure they’re clear of blockages, leaks, or loose connections so CO can escape properly.
Check for warning signs: Look for soot, rust, stains around appliances, or flames that burn yellow or orange instead of blue; these may signal poor combustion.
Keep exhaust areas clear: In winter, always remove snow from your vehicle’s tailpipe before starting the engine.
Limit indoor smoke: Excessive smoking indoors can add to indoor CO levels.
What to Avoid:
Run vehicles in enclosed garages: Even with the door open, carbon monoxide can quickly reach dangerous levels.
Use generators or grills indoors: Gas-powered grills, generators, and similar equipment should only be used outdoors in well-ventilated areas.
Heat your home with appliances not made for it: Never use ovens, gas ranges, or generators as a substitute for a heater.
Operate fuel-powered tools in small spaces: Pressure washers, camping stoves, or lanterns should never be used inside homes, tents, or campers unless properly vented by a professional.

Frequently Asked Questions
Carbon monoxide is a colorless, odorless gas that can be deadly if inhaled in large amounts. It’s produced by burning fuel in appliances like furnaces, water heaters, and stoves. A CO detector alerts you to dangerous levels of this gas, giving you time to evacuate and seek fresh air.
Install a CO detector on every level of your home, including the basement. Place it outside each sleeping area, such as in a hallway near bedrooms. If you have an attached garage, install one nearby, as car exhaust can contribute to CO buildup. Avoid placing detectors near windows, doors, or vents where drafts could interfere with their operation.
While it’s not required, installing a CO detector inside or just outside each bedroom can provide added safety. This is especially important if your home uses gas-powered heating or has an attached garage. Ensure the alarm is loud enough to wake everyone in the house.
CO detectors should be installed at least 5 feet above the floor, at eye level. This placement ensures the detector can sense the gas effectively, as CO mixes evenly with air. Avoid placing them directly on the ceiling unless the manufacturer’s instructions specify otherwise.
Carbon monoxide (CO) can start to accumulate within minutes if there’s a source like a running car in a garage or a malfunctioning heater. The speed depends on the size of the space, ventilation, and the CO source. Even small amounts can become dangerous quickly, which is why detectors are essential.
You shouldn’t rely on symptoms alone to test for CO, because the gas is colorless and odorless. Common symptoms include headache, dizziness, nausea, or confusion. The safest way to know is with a properly installed CO detector. If you suspect exposure, leave the area immediately and seek medical help.
Carbon monoxide has no smell, taste, or color, which is what makes it so dangerous. You won’t be able to detect it without a CO detector, so having one in your home is crucial.
Carbon monoxide mixes evenly with air, so it doesn’t simply rise or fall. This means detectors should be placed according to manufacturer instructions—usually at eye level or on the ceiling to ensure they can sense the gas wherever it collects.
