 Just stay next to the fire when it's blazing. Then, pour water to douse it, stir, and repeat. And finally, check for heat. It'd be a shame if, say, you got lazy and didn't ensure the fire pit was cool to the touch and accidentally sparked the wildfire that wiped out the last of the dinosaurs and your cousin Bunk never shut up about it. Hypothetically, of course. So, douse your campfires. Use your fire sense.
