What safety device is essential for reducing electrical shock risk in wet areas of a facility?

• A. Ground Fault Interrupter (GFI) for safety in wet areas
• B. Circuit breaker only
• C. Tamper-resistant outlets
• D. Power strip with surge protection

Answer: (A)

In wet areas, the main danger is a path for current through a person due to leakage or contact with water. A Ground Fault Interrupter (GFI) continually monitors the current flowing in and out of a circuit. If some current diverts to ground—such as through damp skin or a wet surface—the currents no longer match, and the GFI trips, cutting power in a fraction of a second. That rapid shutoff greatly reduces the chance of a dangerous shock or electrocution.

Circuit breakers protect against overloads or short circuits, not small leakage to ground. Tamper-resistant outlets make it harder to insert objects but don’t address ground faults. A power strip with surge protection helps with surges but typically lacks the fast ground-fault protection needed in wet areas. Because preventing shock in moisture-prone environments relies on detecting and interrupting leakage quickly, the GFI is the essential safety device.
