What measure can reduce the risk of electrical shock in wet environments?

Installing GFCI (Ground Fault Circuit Interrupter) outlets is an effective measure to reduce the risk of electrical shock in wet environments. GFCI outlets are designed to detect ground faults, which occur when there is an unintended path between the electrical current and the ground. In wet environments, moisture increases the likelihood of such faults, making GFCI outlets critical for safety.

When a GFCI detects a difference in the flow of electricity between the hot and neutral wires, it quickly cuts off the electrical supply—usually within milliseconds—thereby preventing severe electrical shock to individuals who may come into contact with the electrical current while in a wet environment. This rapid response is particularly important in areas like bathrooms, kitchens, and outdoor locations where water is present.

In contrast, using metal components could actually increase the risk of shock, as metal conducts electricity. Increasing voltage is dangerous and would elevate the risk of severe injury. Employing dual circuits does not specifically address the problem posed by water and does not provide the same level of quick intervention as GFCI outlets.
