What can cause electric shocks in the body and how can they be prevented?

Electric shocks in the body can be caused by contact with electrical sources such as faulty wiring or appliances. To prevent electric shocks, it is important to ensure that electrical systems are properly installed and maintained, avoid using electrical devices near water, and always use insulated tools when working with electricity. Additionally, using ground fault circuit interrupters (GFCIs) can help protect against electric shocks.
