Solution
Working of blanket : 2 Marks
Use in electrical fires : 1 Mark
If a person’s clothes catch fire (start burning), a blanket must be wrapped over immediately on his/her body. This activity will cut off the supply of oxygen which is a condition for burning(combustion). This will help to extinguish the fire and save the life of that person.
Yes, a blanket can be used for electrical fires since it works by cutting the supply of fire with Oxygen. Only substances which can cause conduction of electricity cannot be used for electrical fires.
