Which defect would be most associated with scaffold access ladders?

• A. Broken handles
• B. Twisted metal stiles
• C. Excessive rusting
• D. Loose fitting

Answer: (B)

The most appropriate defect associated with scaffold access ladders is twisted metal stiles. The stiles are the vertical supports of the ladder, and if they become twisted, this can significantly compromise the structural integrity and stability of the ladder. A twisted stile impacts the ladder's ability to safely support weight and maintain balance during use, increasing the risk of accidents for anyone using the ladder for accessing the scaffold. Other defects like broken handles or excessive rusting may affect the functionality or longevity of the ladder, but they do not directly compromise its structural integrity in the same way that twisted stiles do. Loose fittings might affect how securely the ladder attaches to the scaffolding but do not represent a primary structural failure like the twisting of stiles does.
