If it is necessary to use a ladder at a flatter angle due to site conditions, what is a precaution you can take to prevent the base from slipping back?

To prevent the base of a ladder from slipping back when it is set up at a flatter angle due to site conditions, tying off the bottom of the ladder is an effective precaution. This method secures the base of the ladder to a stable object or surface, reducing the risk of movement and enhancing stability. When the bottom is tied off, it creates a secure anchor point, allowing the ladder to remain in place even if weight is applied or if there are slight shifts in position.

The importance of this precaution lies in the fact that ladders are most prone to slipping when they are positioned at a shallow angle. Ensuring the base remains secure can protect the user from potential falls or accidents. Proper ladder safety practices, including securing the base, are essential for maintaining safety when working at heights.
