At what distance must a ladder be located from an excavation hole?

When positioning a ladder near an excavation hole, it is critical to ensure safety and accessibility. The correct answer specifies that the ladder should be placed 25 feet away from the edge of the hole and that it should extend 3 feet above the hole’s edge. This distance is important because it helps maintain a safe working environment, reducing the risk of falls or accidents while workers are accessing the area around the excavation.

By placing the ladder a sufficient distance away from the edge, you minimize the risk associated with the instability of the ground close to the excavation. Moreover, having the ladder extend above the edge of the hole provides a safeguard for individuals climbing up or down, ensuring they have a secure handhold and can safely transition between the ground and the elevated surface.

In comparison, the other choices provide different distances and heights that either do not meet safety standards or are less than optimal for safe ladder usage near excavation sites. Safety regulations emphasize the importance of maintaining a proper clearance between ladders and excavation sites to prevent accidents, which is highlighted in the correct answer.
