To ensure safety, what is the maximum distance from the wall to the foot of a 12-foot ladder?

The correct answer is the maximum distance from the wall to the foot of a 12-foot ladder is not over 3 feet. This guideline is based on the ratio of the ladder's height to the distance from the wall, which is typically about 4 to 1 for stability. For a 12-foot ladder, this means for every 4 feet of height, the base of the ladder should be 1 foot away from the wall. Therefore, to maintain balance and minimize the risk of falling, a ladder height of 12 feet will ideally have the foot placed approximately 3 feet away from the wall.

This distance is crucial for ensuring that the ladder remains stable while in use. If the foot of the ladder is placed too far out from the wall, the ladder can easily tip over, increasing the chances of accidents and injuries. Thus, adhering to this safety standard is vital for any sewage treatment worker or anyone using a ladder in their work environment.
