How much overlap should planks on scaffolding have if they are not immovable?

• A. 6 inches
• B. 12 inches
• C. 18 inches
• D. 24 inches

Answer: (B)

The recommended overlap for planks on scaffolding, especially when they are not secured in place, is 12 inches. This ensures adequate support and stability for workers and materials on the scaffolding. An overlap of 12 inches provides a balance between safety and practicality, allowing for enough surface area to support loads while also promoting ease of assembly and disassembly. Larger overlaps, such as 18 inches or 24 inches, may provide additional support but can make the scaffolding cumbersome and difficult to work with, potentially affecting efficiency. Similarly, an overlap of 6 inches might not provide sufficient support, increasing the risk of planks shifting during use. Therefore, the 12-inch overlap serves as an effective standard in scaffolding practices, creating a safe working environment while facilitating effective use of the material.
