Basic Electrical Safety Trivia Quiz

It is important to stay at least 10 to 35 feet away from overhead power lines to ensure safety. This distance is necessary to prevent any accidental contact with the power lines, which can be extremely dangerous and potentially fatal. It is crucial to maintain a safe distance to avoid the risk of electric shock or electrocution.

Extension cords should not be repaired using standard electrical tape or any other type of tape. Repairing extension cords with tape can be dangerous as it may not provide proper insulation and can lead to electrical hazards such as short circuits, fires, or electric shocks. It is recommended to replace damaged or faulty extension cords instead of attempting to repair them.

The Ground Fault Circuit Interrupter (GFCI) is a device that provides protection to workers against electrical shorts or imbalances of current in power tools. It works by continuously monitoring the current flowing through the circuit and quickly interrupting the power supply if it detects any leakage or imbalance. This helps prevent electrical shocks and potential injuries to the worker. Circuit breakers and fuses are also safety devices, but they primarily protect against overloads and short circuits, rather than specifically addressing electrical imbalances in power tools. Quick Disconnect, on the other hand, is not a safety device and does not provide protection against electrical shorts or imbalances.

A circuit breaker is a device that is used for over-current protection or to prevent too much current from flowing in a circuit. It is designed to automatically interrupt the flow of electricity when it detects an overload or short circuit, thus protecting the circuit and the connected devices from damage. Unlike fuses, which need to be replaced after they have blown, circuit breakers can be reset and reused. Therefore, a circuit breaker is the correct device for over-current protection or when there is too much current flowing in a circuit.

When plugging devices into an electrical outlet, it is recommended to plug in one device to each socket of a duplex outlet. This is because each socket is designed to handle a certain amount of electrical load, and plugging in multiple devices using multi-plugs can overload the circuit and potentially cause damage or a fire hazard. Therefore, it is safer and more efficient to only plug in one device per socket.

An electrical shock may cause injuries such as electrocution and death, burns, and falls. However, the correct answer is "None of the above" because the question asks for the injuries that an electrical shock may cause, and the given options do not include all possible injuries.
