What position should a lineman avoid when setting pins while using a kelly bar?

When using a kelly bar to set pins, it is crucial for linemen to prioritize their safety and ensure proper technique. The inner position is the least advisable because it exposes the lineman to increased risk of injury. In this position, a lineman is closer to the heavy equipment being operated, increasing the likelihood of being in a hazardous zone where injuries can occur, such as being pinched or struck by moving parts of the machinery.

In contrast, the outer position and middle position provide linemen with more distance from the operation of the kelly bar and improve their ability to react to any potential hazards. Staying in these positions also allows for better visibility and control over the operation, reducing the chances of accidents. Therefore, avoiding the inner position while setting pins helps ensure the safety and effectiveness of the task.
