Solution

Insulators are materials which do not allow electric current to pass through it. Without the help of insulators, the use of electrical tools like pliers and screwdrivers will give an electric shock to the user.

Wood and plastic are insulators which helps in avoiding direct contact with electric current. When electricians touch live electric wires(wires carrying current) with these tools covered with plastic or rubber, current does not flow through their body, which prevents accident.
