How far should an extension ladder be placed from the wall for every 4 feet of vertical length?

The correct way to position an extension ladder is to set its base at a distance from the wall that is one-quarter of the ladder's vertical reach. This means that for every 4 feet of height, the base of the ladder should be placed 1 foot away from the wall.

This ratio ensures stability and minimizes the risk of the ladder slipping or tipping over while in use. By adhering to this guideline, users can maintain a safe angle when climbing, giving them better control and reducing the likelihood of accidents.

When considering the other options, a distance of 2 feet, 3 feet, or 4 feet for every 4 feet of vertical length creates an angle that is either too steep or too shallow, which can compromise safety. It's essential to follow this established rule for optimal safety during ladder use.
