What factor increases the risk of falling when using a ladder?

When considering factors that increase the risk of falling while using a ladder, the position of the ladder is particularly crucial. The way a ladder is positioned can significantly affect its stability and balance. If a ladder is placed on an uneven surface, against a slippery wall, or at an improper angle, it can become unstable, leading to a higher risk of falling. A proper setup requires that the ladder be on stable, level ground and positioned at the correct angle (generally 75 degrees) to ensure safety.

Although other factors such as the weight of the user, the type of ladder, and the height can contribute to risks associated with ladder use, the position directly affects how secure the ladder is while in use. For example, a properly positioned ladder can help distribute weight evenly and maintain stability, whereas an incorrectly positioned ladder can cause it to shift or collapse. Thus, understanding and ensuring the correct positioning of a ladder is vital to minimize fall risks during construction activities.
