What safety measure should be taken when using extension cords?

The correct choice emphasizes the importance of ensuring that extension cords are rated for the specific use required and that they are thoroughly inspected for any signs of damage before use. This is crucial for maintaining safety while using electrical equipment. Extension cords must be chosen based on their electrical capacity to handle the load they will carry; using a cord with an inadequate rating can lead to overheating and potential fires. Additionally, inspecting cords for any damage—like frayed wires or exposed conductors—helps prevent electrical shocks and short circuits.

Safety best practices dictate that extension cords should be treated with care, and by verifying their ratings and conditions, users can significantly reduce the risk of electrical hazards in their work environment.
