What should a worker do before touching circuit conductors and parts where induced voltages or stored energy may exist?

Before touching circuit conductors and parts where induced voltages or stored energy may exist, a worker must first de-energize all circuit conductors and parts. This is a critical safety procedure because even when equipment is turned off, there can still be residual or induced voltages that pose a significant risk of electric shock. De-energizing the circuits ensures that the worker is not exposed to any live electrical parts, which is essential for their safety.

The importance of this procedure lies in its role in preventing electrical accidents. Without ensuring that the circuits are de-energized, a worker may inadvertently energize the system or encounter unexpected voltage, leading to potentially life-threatening situations. Following this step is a fundamental aspect of electrical safety protocols.

In context, while inspecting the area for electrical hazards, checking with colleagues, or using insulated tools can contribute to a safe work environment, these actions do not eliminate the inherent risks associated with touching live circuit conductors. De-energizing is the primary safety measure to protect the worker from electrical hazards.
