Since you probably already know what to do better than I do, the information below is for people who don't:
If you're going to have a fire, chances are it will be in the galley. If it's in a pot or fryer, you might be able to put a lid on it and smother it. Another thing that could help is a box of baking soda. Pour that on liberally and it'll usually kill a cooking fire, too. Of course, if the fire is on the ground, use water or smother it with dirt.
A chuckle for you:
In a college cooking class, I had to broil some fish. I hate most fish. Fortunately, my fish caught fire. I thought fast and smothered them with baking soda. I got a 'B' for that day's class and everyone wanted to know why. The professor said it was because I knew what to do when the fish caught fire, didn't lose my head and acted fast.
I smiled because not only did I get a 'B' for that day's class but also, I didn't have to eat fish!

There is a new product, a small fire blanket that just came out that smothers fires. I saw it online. If I see it again, I'll try to remember to post it for you, in case you're interested.
