What is the recommended base placement for a ladder when setting it up?

1/4 of the length of the ladder
1/3 of the length of the ladder
1/2 of the length of the ladder
1 inch per foot of ladder length

The correct answer is: 1/4 of the length of the ladder

The recommended base placement for a ladder is determined by a safe angle that maximizes stability while minimizing the risk of tipping. The correct approach is to place the base of the ladder at a distance that is one-quarter of the overall length of the ladder from the wall or support it is leaning against. This placement ensures that the ladder maintains an optimal angle, usually around 75 degrees with the ground, which is essential for safe climbing and working. When the ladder is set up correctly at this base distance, it reduces the likelihood of the ladder slipping or tipping over, providing a secure and safe working environment. Distances that are too far or too close can lead to instability, making it critical for anyone using a ladder to adhere to this guideline.
