What should be the first step before performing work on electrical systems?

• A. Wearing protective equipment
• B. Ensuring all tools are inspected
• C. De-energizing the circuits
• D. Consulting a supervisor

Answer: (C)

The first step before performing work on electrical systems should be de-energizing the circuits. This procedure is crucial for ensuring safety when working on or near electrical equipment. De-energizing the circuits eliminates the risk of electric shock or electrocution, allowing workers to perform their tasks without the immediate danger posed by live wires and energized components. This process involves turning off the power to the circuit and confirming that it is indeed de-energized, typically through the use of appropriate testing equipment. After ensuring de-energization, other safety measures can be implemented, such as wearing protective equipment or inspecting tools. However, without first de-energizing the circuit, these actions cannot adequately protect the worker from the inherent dangers of working with electricity. The sequence of operations is fundamental to electrical safety practices, which prioritize de-energizing systems as the initial step to create a safe work environment.
