When sodium hydrogen carbonate is mixed with water, it produces carbon dioxide gas. This gas helps to smother the fire by displacing the oxygen that the fire needs to burn.<\/p>\n<p>Sodium hydrogen carbonate is also a relatively safe substance to use. It is not flammable and does not produce toxic fumes when it is heated.
