Used lumber must have all nails withdrawn before stacking and is not to be stacked over what height?

The regulation regarding the stacking height of used lumber primarily aims to ensure safety in construction sites. When used lumber is stacked, it must not exceed a height of 20 feet. This limit is in place to prevent potential hazards, such as toppling or instability, which can occur if the lumber is stacked too high.

By enforcing a maximum height, this regulation helps to maintain a safer working environment, as excessively high stacks can be difficult to manage and increased risk of injury from falling materials. Additionally, the requirement that nails must be withdrawn before stacking used lumber demonstrates a commitment to preventing injuries caused by sharp objects sticking out, which further underscores safety practices in construction.

Understanding this regulation is essential for contractors to ensure compliance with safety norms and promote a secure working atmosphere on job sites.
