Question
Give reasons.
Water is not used to control fires involving electrical equipment.
Solution
The most common fire extinguisher is water. But water works only when things like wood and paper are on fire. Water is a good conductor of electricity. However, if it is used to control a fire involving electrical equipment, the person dousing the fire might get an electric shock. Water can also damage electrical equipment. Water is also not suitable for fires involving oil and petrol.
