Assuming there are no heaters... etc inside that burn fuel.
Maybe outside generator, truck exhaust coming inside?
You may have a CO/Propane detector. Every breath we exhale contains CO2, is what plants need to survive, and is always in the atmosphere. CO (carbon monoxide) is the product of incomplete hydrocarbon combustion and is toxic to us.
If you have a range/oven that is not burning propane correctly, it can produce CO. That's one of the main reasons for always running a vent fan while cooking.
I'm sure she is talking about the propane detector - I have had it alarm enough to have figured out why. The post I linked discusses several of the reasons - the oddist is the dog farts.
