Get Knowledgable about Indoor Gases Carbon Monoxide (CO) — Carbon monoxide is a dangerous, life-threatening gas that may be fatal, and that can lead to flu-like symptoms over time. You can read more about it on our Carbon Monoxide page. Natural Gas — Natural gas is normally safe, but it can potentially pose a threat if a pilot light is out in a stove, a gas fireplace, or a furnace, or if there is a leak. Thankfully, natural gas can be detected due to its strong odor, making it easier to detect. The gas itself is not poisonous. The problem is that natural gas is heavier than oxygen, and displaces the oxygen we breathe, leading to asphyxiation. It can also gather in the basement, and—under the right circumstances—explode. No. Not good. We encourage you to purchase a natural gas detector. They’re affordable and a cinch to operate. If you smell gas, don’t turn lights or appliances on or off, as even a small electrical current could cause an explosion. Leave the area immediately and call your Dayton natural gas utility. Radon — Radon is a colorless and odorless gas that can only be detected by testing. This radioactive gas comes from the natural breakdown of uranium in soil, rock and water. It’s found in much of North America, though some regions have much higher concentrations. Unmitigated radon may cause cancer, and is responsible for 21,000 lung cancer deaths annually. A simple do-it-yourself air test can determine where your radon level is at. If levels exceed the recommendations, a radon reduction contractor can assist with a solution. Other Gases and Vapors — Other gases and vapors are released from vehicles in the garage, from tobacco use, from cleaning products, and the more than 300 chemicals used in household furnishings, construction materials, carpeting, flooring, and paints. All these gases may produce odors and gasses that can irritate our respiratory systems, and could further complicate asthma and allergies. Tips — Here are some recommendations to help control exposure to gasses, fumes and odors: Be sure your home includes proper ventilation. Call us for a free ventilation system analysis. Install a carbon monoxide detector, a natural gas detector, and be sure to test the radon levels in your home. Keep interior doors closed that are near the garage, and leave the garage door open at least 5 minutes after a car enters or leaves. If you have a wood-burning stove or fireplace, extinguish all burning embers before shutting the flue. Keep the door open to any room that does not have a return vent. Reduce the amount of tobacco smoke in the home. Use non-toxic or organic cleaning products.
