What does the term 'energized' refer to?

The term 'energized' refers to equipment or machinery that is connected to an energy source, which may include electrical power, hydraulic pressure, air pressure, or any similar energy supply, as well as any equipment that contains stored energy such as springs or capacitors. Understanding this definition is crucial in the context of Lockout/Tagout (LOTO) procedures, as the primary goal of these procedures is to ensure that machinery is adequately de-energized before maintenance or servicing begins.

In an energized state, machines can pose significant hazards to workers, as unexpected movement, release of stored energy, or exposure to electrical currents can lead to injuries. Therefore, recognizing when a machine is energized is essential for implementing safety measures that prevent accidental start-up or the unintended release of energy, thereby protecting workers during maintenance tasks.
