Carbon monoxide is a very dangerous gas. This is because of several reasons. It is invisible and doesn’t have a smell, so you can’t easily detect it. On top of that, it is very easily generated by many of the things that we use every day. Anything that works by combustion generates carbon monoxide, but usually the gas is funneled away to keep from harming you. However, if for any reason, there is carbon monoxide released in the air where you are, it could kill you in as little as 5 minutes in a high enough concentration.
Common symptoms of carbon monoxide poisoning are dizziness, nausea, and shortness of breath, all of which makes it more difficult for you to think straight and get away from the gas quickly.
Your best protection against carbon monoxide gas is to have CO alarms in your home, especially in areas where the gas is more likely to be released.
