What should be done before loading materials on trusses?

Before loading materials on trusses, it is essential to brace the trusses. Bracing provides structural support and stability to the trusses, ensuring that they can safely handle the loads applied during construction. This process is crucial to prevent any potential deformation or failure of the truss system once materials are loaded.

When trusses are properly braced, the weight they will bear is evenly distributed, which helps maintain their integrity throughout construction and avoids accidents or damage. Proper bracing also assists in keeping the trusses aligned and prevents them from swaying, which is particularly important in windy conditions or when other loads are applied.

While other options such as painting, measuring, or installing decorations may be relevant in specific contexts, they do not address the immediate structural concerns that arise from loading materials onto trusses. Bracing is a foundational step that ensures safety and stability during the loading process.
