I would recommend making sure you have a good burner, GOOD VENTILATION, a good regulator inside, and run the hose, or pipe to outside the house.
There are plenty of commercial kitchens, stoves, and home ranges etc that use propane.
If you are very concerned about the safety of it and still feel uncomfortable you can get a propane detector, and hook it up to a solenoid shutoff valve, so that if leaks happen and propane is getting in the atmosphere around your cooking area it would automatically shut off the flow.
I just edited this to say, that Ventilation is extremely important if done inside.
