Which of the following is an example of a safety precaution in electrical work?

• A. Ignoring frayed wires
• B. Using non-insulated tools
• C. Using GFCIs
• D. Operating in wet conditions

Answer: (C)

Using Ground Fault Circuit Interrupters (GFCIs) is a critical safety precaution in electrical work because they are designed to protect against electrical shock. GFCIs continuously monitor the flow of electricity and can detect imbalances between the outgoing and incoming currents. If an imbalance is detected, such as when electricity is flowing through a person to the ground, the GFCI quickly shuts off the power, minimizing the risk of serious injury or fatal electrocution. In contrast, the other options do not promote safety. Ignoring frayed wires can lead to short circuits or electrical fires. Non-insulated tools can conduct electricity and pose a risk of shock. Operating in wet conditions increases the likelihood of electrical hazards, as water is a good conductor of electricity and significantly raises the risk of injury. Therefore, using GFCIs is fundamental to ensuring safe practices when working with electrical systems.
