Sodium bicarbonate reacts with heat to become sodium carbonate. You need a pretty high temperature of more than 518 degrees Fahrenheit to create this reaction. This should happen easily when in contact with flames.

Why is sodium bicarbonate used in fire extinguishers?

Baking soda, (sodium bicarbonate) is used in class C fire extinguishers. When sodium bicarbonate (baking soda) is heated by the fire it becomes sodium carbonate. The carbon dioxide starves the fire of oxygen smothering the fire and the water that is released cools the heat source.
