On the indoor propane (LP) issue, remember that the wrong fuel/oxygen mixture can result in substantial CO production.

Most, but not all, propane and natural gas appliances are vented outdoors, which isn't the case when you bring a campstove inside, which I wouldn't do. The non-vented approved appliances (I have two), always use a thermocouple to sense the mixture (indirectly) and shut off the flame if it gets too hot. California and a couple other states don't allow the non-vented appliances. Stove tops are treated a little differently.

For added security I keep two CO alarms, one fancy and one not, in the area when the non-vented appliances are used. They have never shown any CO accumulation above background because the mixture in the heaters is correct. It is also good to have a gas detector to detect those leaks. My wife's relatives in India do use "cooking gas" appliances indoors but they have decades of experience doing so safely. I wouldn't try it myself.

I have a propane refrigerator and it is unvented. It is GREAT for times like these. I don't worry about it, but to keep the peace, I have two CO alarms in the area! (They have never alarmed)
