What is the first step to take before working on energized equipment?

The first step to take before working on energized equipment is to turn off the power. This is critical because de-energizing the equipment eliminates the risk of electric shock or other injuries that can occur while working on live systems. When the power is turned off, it not only provides a safer environment for the technician or worker but also allows for proper inspection and maintenance of the equipment without the worry of unintended activation.

Other options, while important, come into play after ensuring that the equipment is safe to work on. Wearing personal protective equipment (PPE) is essential for safety, but it is most effective if the equipment is not energized. Notifying a supervisor is a good practice, especially in a team environment, and reviewing safety protocols is essential for overall safe operation. However, these steps should follow the critical action of de-energizing the equipment to ensure the safety of everyone involved.
