The handles of the tools like screwdrivers and pliers used by electricians for repair work usually have plastic or rubber covers on them. Can you explain why?
Share
Tool handles have plastic or rubber covers to protect electricians. These covers act as insulation, preventing contact between hands and metal tools. By providing insulation, they reduce the risk of electric shock when working on electrical repairs, ensuring the safety of the electrician.
Without the help of insulators, the use of electrical tools like pliers and screwdrivers will give electric shock to user. Wood and plastics are insulators and help in avoiding direct contact with electric current. When electricians touch these live electric wires with these tools covered with plastic or rubber, current does not flow in their body making safer them from any accident.
