If a ladder has a broken rung, what is the best practice?

When dealing with a ladder that has a broken rung, the safest and most prudent action is to discard the ladder. A broken rung compromises the structural integrity and safety of the ladder, making it inherently dangerous to use. This is critical because ladders are designed to support the weight of the user and any additional tools or materials they may carry. A failure in any part of the ladder, especially one that supports weight, can result in severe accidents or injuries.

Repairing the rung using adhesives or ties, such as duct tape, electrical tape, or tie wire, does not provide a reliable or safe means of restoration. These materials may not be able to bear the weight or stress that a ladder is subjected to during use. Therefore, even if a temporary repair might seem feasible, it does not ensure the same level of safety as an intact and fully functional ladder would provide. Discarding the ladder eliminates any risk associated with a compromised piece of equipment, ensuring that users are not exposed to potential hazards.
