Do not use it inside.

[Petronski]

Let's be more specific. Do not use propane indoors.

It produces CO, it can tip and cause fires, and unburned propane is heavier than air, which can pool in basements and go boom. (Natural gas is lighter than air...)

YES YOU CAN USE A CAMPING STOVE FUELD BY PROPANE INSIDE, GAS RANGES ARE USED EVERYDAY INSIDE HOMES, QUIT BEING STUCK ON STUPID.
