Why do you not use flour on a grease fire?

You should never use flour on grease fire because flour is a combustible material and can easily catch fire. When you add flour to a grease fire, the small particles of flour can become suspended in the air and create a dust cloud. This dust cloud can then be ignited by the heat of the fire, causing a fireball. Additionally, the flour can also absorb the grease, which will make the fire even harder to put out.

Therefore, it is important to never use flour on a grease fire. Instead, you should use a fire extinguisher or baking soda to put out the fire.
