Q4 What are the three main ways in which a �re can be controlled or put out?

Answer. Fire can be controlled or put out by taking away one of the three things required for
burning.The �rst way is to take away the fuel. If the �re has no fuel to feed on, no burning can
take place.The second way is to prevent oxygen from reaching it. Small �res can be put out with a
damp blanket or a sack. This stops oxygen from reaching the burning material. Sometimes
carbon dioxide is used for extinguishing �re.
The third way of putting out a �re is to remove the heat. If the temperature can be brought down
below the �ash point, the fuel stops burning. Blowing on a burning matchstick or a candle
removes the hot air around the �ame, bringing down its temperature below the �ash point.
Sometimes water is sprayed on a �re. It absorbs heat from the burning fuel and lowers the
temperature. It also cuts off the supply of oxygen, and therefore, �re is extinguished.

Q6 Why does a burning candle go out when you blow on it?

Answer. When we blow air on a burning candle, we remove the hot air around the �ame. In this
way, we reduce its temperature below the �ash point. Thus, the candle goes out.

Q7 Spraying water is not a good way of putting out an oil �re or an electrical �re. Why not?

Answer. If water is sprayed onto an oil �re, then the oil will �oat to the top of the water and
continue to burn. This can be very dangerous because water can �ow quickly, carrying the
burning oil with it and spreading the �re. In case of an electrical �re, the person spraying water
might receive an electric shock and be killed. Therefore, spraying water is not a good way of
putting out an oil �re or an electrical �re.
