You do know not to pour water on burning oil, right? Or straight whiskey onto a fledgling flame. If it's a mixed drink, use your judgment.... Who mixed it? With what? How much ice?
Tongs, spatulas, and small shovels are good things to keep near a barbecue, maybe a box of baking soda in the kitchen. Other ideas include always inviting at least one experienced fire fighter to all of your barbecues, or, hell, serving the meat raw. Now you know how.
