 It's a bigger fire than you'll need to smother it by dumping either baking soda or salt on it. Just make sure it's baking soda, not baking powder, or else you'll be in for an unfortunate surprise. If you don't have either of those things handy or if the fire is already too large to contain that way, then use your fire extinguisher. And if you don't have a fire extinguisher, then hopefully you have a fire blanket. If you don't have a fire blanket and you can't smother it with a lid and you don't have baking soda or salt or the fire is too big by this point to put it out that way, then just toss yourself into the fire as penance for being so woefully unprepared.
