What is grease fires?

Grease fires are a type of fire that occurs when cooking oils or fats ignite due to high temperatures. They typically happen when overheated oil reaches its flash point, leading to flames that can spread rapidly. Unlike regular fires, water should never be used to extinguish grease fires, as it can cause the fire to flare up further. Instead, using a fire extinguisher rated for grease fires, smothering the flames with a lid, or using baking soda can help safely contain the fire.
