Sometimes water is sprayed on a fire. It absorbs the heat from the burning fuel. Blanket of water also cuts of the oxygen and the fire gets extinguished.

Sometimes water is sprayed on a fire. It absorbs the heat from the burning fuel. Blanket of water also cuts of the oxygen and the fire gets extinguished. But sometimes spraying water cannot put out the fire. It is not a good way of putting out an oil fire or an electrical fire. When water is sprayed onto an oil fire, the oil will float to the top of the water and continue to burn. This can be very dangerous because water can flow quickly carrying the burning oil with it and spreading the fire. The person spraying water on an electrical fire might receive an electric shock and be killed.

If the fire has no fuel to feed on, no burning can take place. • By cutting the supply of oxygen from reaching it. • By bringing back the temperature below ‘flash point’ of the fuel.
