Why is it important to maintain uniformity of ladder rungs?

Maintaining uniformity of ladder rungs is crucial for safety reasons. When ladder rungs are consistent in spacing and alignment, it reduces the risk of slips, trips, or falls when a user climbs or descends. Inconsistent rung spacing can confuse the user, leading to missteps or loss of balance, which could result in accidents. Each rung needs to be predictable in height and width to provide a stable surface for footing, allowing individuals to feel confident while using the ladder. This uniformity directly contributes to the overall safety of the ladder and the individuals who use it, making it the primary reason for ensuring the rungs are uniformly constructed and maintained.
