Why is it essential to use rubber gloves when working with electrical systems?

Using rubber gloves when working with electrical systems is essential primarily to prevent electrical shocks. Rubber is an excellent insulator, meaning it does not conduct electricity. When a worker wears rubber gloves, it creates a barrier between their skin and any potential electrical current. This significantly reduces the risk of electric shock, injuries, or fatalities that can occur if the body comes into direct contact with energized components.

While gripping tools, moisture prevention, and sensitivity to electrical currents are important considerations in an electrical environment, they do not directly address the primary concern of safety from electric shock. The fundamental role of rubber gloves is to act as a protective measure against electricity, ensuring that workers can perform their tasks safely while minimizing the risk of electrical hazards.
