Sand basically provides a coat over the burning material and cuts off the oxygen supply which extinguishes the fire. The same function is served with water or any type of soil for the A class of fire. So sand per se does not react chemically with the fire being an inert material.Click to see full answer. Subsequently, one may also ask, is sand or sugar better to put out a fire?Fact is both sand and carbon dioxide can stop a fire by cutting of the heat (this is for sand since it has a high melting point, silicon dioxide) or oxygen ( carbon dioxide diffusing to the areas around the fire cutting off oxygen supply). And I advise that the fire extinguisher is better, if only well maintained.One may also ask, why should we use sand and not water when there is a fire at a petrol pump? The fire at petrol pumps is mainly due to oil leakages. If we use water to extinguish the fire it does not workout because water do not mix with oil and settles at bottom. Also there are sand buckets in the petrol pumps which are used to extinguish fires. Sand is poured on fire to prevent it from getting oxygen. Also question is, does sand catch on fire? Sand is silicon dioxide and it a very stable and abundant compound. The silicon atom shares its valence electrons with those of two oxygen atoms and no further oxidation; aka burning, is possible. If the compound is subjected to high temperatures, it simply melts into a glass structure.How do you quench an electrical fire?To put out an electrical fire, unplug the appliance or shut off the power to disconnect the electricity. Consider calling emergency services before putting out the fire, just in case it gets out of hand. You can smother a small fire with baking soda if you have that nearby.
