Fires and baking soda. Use Baking Soda as a Fire Extinguisher
Baking soda (bicarbonate of soda) is effective as a fire extinguisher for grease and electrical fires. When Baking Soda is heated it releases carbon dioxide (just as when dough rises) and produces water. Since carbon dioxide is heavier than air and does not support combustion like oxygen does, it smothers the fire while the water that is formed cools the fire to below the ignition temperature. Unlike any other household chemical, baking soda both cools and smothers a fire.
So it is a great idea to have a tub of baking soda in the, garage, workshop, trunk of your car or anywhere that you could be at risk of fire.
If you are a avid model maker, welder or any job where you need to use a naked flame, you would find that extinguishing any small fire with baking soda will not involve your whole project becoming a soggy disaster.
