Why is water not used for extinguishing fire by petrol and fire in electrical appliances explain in detail
Answers
Water isn't used for extinguishing fire in cases of any electrical fault or fossil fuel fires.
Explanation:
The reason is simple. Water would act as a conductor instead of acting as a resistor and would increase it rather than putting out fire. In case of electrical appliances, you must already know that if water is poured over it, the risk of electrical shock increases. So, it is not advisable to use water to put out fires in electrical appliances.
You must've noticed sand buckets in petrol stations. Water isn't used to put out fires in petrol pumps because water might increase the intensity of the fire. Here sand acts as a better alternative to put out fire.
Answer:
Pure water is not a conductor of electricity. But when it get mixed or dissolved with other materials, it becomes a good conductor of electricity. Petroleum products and oils have lesser density and float on water. The fire will keep burning and even get worse. So fire extinguishers or sands are used to extinguish electrical fire or fire petroleum products or oil.
