Stability is critical for safety; an unstable ladder can lead to falls, which are a leading cause of injuries in the construction industry. The correct angle for a ladder is generally about 75 degrees from the ground, which helps maintain balance and minimizes the risk of tipping over.

Avoiding overreaching is equally important. When you overreach while on a ladder, you risk losing balance and control, which can lead to falls. It's essential to keep your body centered between the ladder's side rails and to move the ladder when you need to access a different area rather than stretching beyond your safe reach.

The height of the ladder does not inherently ensure safety; a ladder must be appropriately used according to the tasks at hand. Holding a ladder by a coworker can be helpful in some circumstances, but it does not replace the need for proper ladder placement and stability. Therefore, ensuring that the ladder is stable, at the correct
