What is used to put out a small grease fire?

• A. Baking soda
• B. Water
• C. Salt
• D. Flour

Answer: (A)

When a small grease fire starts, the aim is to smother the flame by removing heat and cutting off oxygen. Baking soda works well for this because it releases carbon dioxide when heated, which blankets the fire and cools the area, helping to stop the combustion. Water should never be used on a grease fire; it can cause the burning fat to splash and violently erupt as the water turns to steam, spreading flames. Salt and flour aren’t reliable options either—they don’t effectively smother the fire, and flour in particular can create a combustible dust cloud that might ignite. So, for a small grease fire, baking soda is the best choice. If the fire grows beyond control, evacuate and call emergency services.
