Wrong vs. right way to put out a grease fire | Ohio State Medical Center
Splashing water on hot oil makes it spatter, and that’s especially dangerous if the oil is on fire. While you can douse burning wood with water—as when putting out a campfire—this is not how to handle a grease fire in the kitchen. Don’t dump flour on it, either: Flour can be flammable.
If a small grease fire starts while you are cooking, the best way to put it out is to slide a lid over the pan to smother it, then leave the lid in place until the pan is cool. If you can’t do this quickly and easily, get out of the house and call 911.
Another good option is a fire extinguisher, which you should have in your kitchen anyway. Grease fires require a B or K extinguisher (K is for commercial kitchens, while B is appropriate for small grease fires in home kitchens) so an “ABC” home extinguisher is a good option.
