For peace of mind, you can get a fire extinguisher ball that will burst and suppress the fire automatically when it detects that the temperature has hit or exceeded 165F. I can't recall the brand I have, but some come connected to a hanger, so I zip tied it to the center support bar at the top of my tent. Ah,
here is one though I bought mine from the manufacturer directly (AFG) and not the company associated with the link. I also have 2 additional fire balls that I've set next to my power strips...again, just for peace of mind.
