In what situation would a lineman need to perform a static discharge?

A lineman would need to perform a static discharge before working on energized equipment to prevent electrical shock because this process is crucial for ensuring safety when handling live electrical systems. Static discharge helps to neutralize any built-up voltage on the lineman's body, which can be generated through different means, such as movement or friction. By doing so, the lineman reduces the risk of an electrical shock that might occur if a charge were to jump between the lineman and another object or person, potentially leading to serious injury or fatality.

Performing this procedure is a standard safe practice that reinforces the importance of taking necessary precautions when engaged with energized systems. This helps ensure not only the safety of the lineman but also of others nearby.
