How much should scaffold boards overlap when installed?

In scaffold installation, the overlap of scaffold boards is crucial for ensuring stability and safety. An overlap of 10" to 12" is generally recommended because it provides adequate support and minimizes the risk of the boards shifting or slipping during use. This overlap helps distribute the load evenly and allows for a secure connection between the boards, which is essential when workers place heavy materials or equipment on the scaffolding.

Having this amount of overlap ensures that the structural integrity of the scaffold is maintained, allowing workers to operate safely at heights. It is important to adhere to these guidelines, as insufficient overlap could lead to accidents or structural failure. Proper installation techniques, including using a minimum overlap of 10" to 12", contribute to the overall safety measures in masonry and construction work.
