What parts of your house should you put a carbon monoxide alarm?

They should be near bedrooms and the cold air return for the HVAC system.

Carbon Monoxide is an odorless and colorless gas. The issue would become even worse should you be asleep. I have one placed near the bedrooms. I also have one in the Kitchen.

They also make little button detectors for your automobiles. I have one in all of my cars and in the plane.

The symptoms of monoxide poisoning are similar to getting the flu. That is part of what makes this so problematic. If you have a monoxide leak in your home, you can start having flu like issues. The tendency is to stay home and get better. Unfortunately, this means to get more monoxide and get sicker.

It is possible to die from Carbon monoxide poisoning.
