What are grease Fires?
A grease fire happens when your cooking oil becomes too hot. When heating, oils first start to boil, then they'll start smoking, and then they'll catch on fire. Most vegetable oils have a smoking point around 450°F, while animal fats like lard or goose fat will start smoking around 375°F.
In an Event Where a Grease fire occurs, here are some steps to put it out:
Turn the Heat Off - Don't try to move the pot. You might accidentally splash yourself or your kitchen with burning oil. And that would be bad.
Cover the Pot with a Metal Lid - Fire cannot exist in the absence of oxygen. With the lid on (and the heat off), the fire should quickly consume all the oxygen and put itself out. Use a metal lid since glass will shatter.
Pour on Baking Soda - Baking soda will extinguish grease fires, but only if they're small. It takes a lot of baking soda to do the job.
Spray the Pot with a Class B Dry Chemical Fire Extinguisher - This is your last resort, as fire extinguishers will contaminate your kitchen. Still, it's better than the alternative if the fire is getting out of control.
Get Out and Call 911 - If the fire does break out of control, don't try to be a hero. Get out and find a phone to call 911.
