What Does a Carbon Monoxide Detector Do and How Does it ...

· The CO alarm sounds if your sensor detects a buildup of carbon monoxide in your home—usually before you start sensing symptoms. With a low CO level (50 ppm), it may take up to eight hours for the alarm to go off. Higher levels (over 150 ppm) can trigger an alarm within minutes. 3. Act quickly when an alarm sounds because low doses over long periods can be just as dangerous as …

CO and CO2 – What’s the difference? |

CO - carbon monoxide and CO2 - carbon dioxide are often confused. While the names sound similar they are completely different gases with entirely different makeups. While both are colorless, odorless and tasteless gases and have the word "carbon" in their name they are not the same. The biggest difference is that CO2 is a common, naturally occurring gas found everyday from decaying plant and ...
