Question

Electric wires were being changed outside Meenu's house. She observed that electricians were wearing rubber gloves and shoes. The tools used by them were also covered with rubber or plastic material. They asked Meenu to stay away from the wires. Now, answer the following questions using above information:

1. Why did electricians wear rubber gloves and rubber shoes?

2. Why are the handles of tools made up of plastic or rubber?

3. Will you use water to control fire caused by electricity?

Accepted Answer

Rubber is an insulator, whereas, human body is a conductor. Thus, to prevent human body from direct contact with electricity, electricians wear rubber gloves and shoes. This will protect them from electric shock.

Rubber and plastic are insulators. The rubber or plastic handle of the tools will protect the electrician from electric shock.
