A qualified worker must be trained to recognize what?

A qualified worker must be trained to recognize energized parts because this knowledge is critical for ensuring safety while working with electrical systems. Recognizing energized parts is a fundamental aspect of electrical safety; it helps prevent accidental contact with high-voltage components, which can lead to severe injuries or fatalities. This training includes understanding how to identify live wires, circuits that are under voltage, and other components that may pose a risk if touched without proper precautions.

Understanding energized parts is essential not only for personal safety but also for maintaining a safe working environment for all personnel on site. Proper identification helps workers implement the appropriate safety measures, such as using insulated tools or wearing protective gear, thus mitigating the risk of electrical accidents.
