Explanation:
pour water on the fire water cools the comparison material so that its temperature is brought below its ignition temperature this prevents the fire from spreading water vapour also Surround the combustible material helping in cutting off the supply of air show the fire is extinguished you have learnt that there are three essential requirements for providing fire this a fuel,air (to supply Oxygen)and heat (to raise the temperature of the fuel beyond the ignition temperature)fire can be controlled by removing one or more of this requirement the job of a fire extinguisher is to cut the Sapne of the air so that they can bring the temperature of the fuel or or both down the most common Fire extinguisher is water but water was only when things like wood and paper are on fire if electrical equipment is on fire water main conduct electricity and those trying to close the fire water is also known suitable for 5 involving oil and petroleum 45 in Golden electrical equipment and inflammable materials like petrol,carbon dioxide is the best extinguisher kahan per dioxide been heavier than oxygen covers the fire like the blanket the added advantage of carbon dioxide research in most case it does not harm the electrical equipment dry powder of chemicals which sodium bicarbonate (baking soda) or potassium bicarbonate near the fire is Chemicals give off carbon dioxide..
