What are some safety precautions for a wildfire?

Dig a trench of some sort around the fire and make sure you have plenty of water and other firefighting supplies. Also try to keep flammable objects as far away from the fire as possible. Treat it like a bad storm - find a safe place and don't go wandering out into it. (Joking answer) ----> If you had a huge dome you could just cover the fire, cut off the oxygen supply, then everything would be fine. Just make sure there aren't any hot coals lying around.
