What is the correct foot position to building height ratio when setting up an extension ladder?

• A. 2:1
• B. 3:1
• C. 4:1
• D. 5:1

Answer: (C)

The correct foot position to building height ratio when setting up an extension ladder is a 4:1 ratio. This means that for every four feet of height that the ladder reaches, you should set the base of the ladder one foot away from the building. This ratio provides stability and helps prevent the ladder from tipping over or slipping, ensuring a safer climbing experience. When the ladder is placed at a 4:1 ratio, it creates a proper angle relative to the ground, generally around 75 degrees. This angle allows for better weight distribution and is essential for the safety of the person using the ladder. If the ladder is set up at a steeper angle, it may become unstable, while a shallower angle can increase the likelihood of a fall due to insufficient support. Understanding proper ladder setup ratios is crucial for anyone working with ladders, as it directly influences user safety and effectiveness during various tasks.
