When using a device to move a victim away from a power source, what should the device be made of?

When moving a victim away from a power source, the device used should ideally be made of materials that are non-conductive to minimize the risk of electric shock to the rescuer. The correct answer is wood or plastic because both materials are poor conductors of electricity. This property helps ensure that any accidental contact with live electrical circuits does not result in the conductor transferring electricity to the person using the device.

Rubber, while also a non-conductive material, is less commonly used in a broader context for rescue devices compared to wood or plastic. Metal, on the other hand, is a good conductor of electricity and poses significant danger in an electrical situation. Glass is also not ideal; while it can be non-conductive, it is brittle and might shatter under stress, which could create additional hazards during a rescue operation. Therefore, the safest and most effective choice is to use a device made of wood or plastic.
