What should be done with a ladder when it is not in use?

When a ladder is not in use, the most appropriate action is to lay it down or lash it securely. This approach minimizes the risk of accidental tipping or falling, which can lead to potential injury or damage. Laying the ladder flat prevents it from becoming a tripping hazard and ensures it remains in a stable position until it is needed again.

In contrast to this correct action, simply leaning a ladder against a wall poses a risk because it can fall over if bumped or disturbed. Keeping it in an upright position, while it may seem safe, can also lead to instability if not properly secured. Disposing of the ladder is not practical and disregards safety measures for maintaining equipment. Thus, laying it down or lashing it is the best method to ensure safety and protect the ladder itself when it is not actively being used.
