At airports or petrol pumps the probability of breaking fire from oils are more. In case of fires due to oils, soda-acid fire extinguisher is not successful, because it uses water to cool the combustible substance. But water is lighter than oil and settles down the oil particles and fire cannot be controlled. In such case Hydrocarbon fire extinguisher is used which has turkey red oil, which causes the foaming of carbon dioxide under pressure. The foam covers the surface of burning substance and cuts off the supply of air to control fire.
