What is a significant consideration when tightening clamps during scaffold assembly?

Ensuring the horizontal tubes are supported is a significant consideration when tightening clamps during scaffold assembly because proper support is essential for maintaining the stability and safety of the entire scaffold structure. When horizontal tubes are adequately supported, they help distribute weight evenly and prevent swaying or collapsing, which could lead to accidents or injuries.

Correctly securing these components ensures that the scaffold meets safety standards and can bear the intended loads without risk of failure. This consideration is fundamental to creating a safe working environment for personnel who will be using the scaffold.

Other factors, such as cable colors or whether to use power tools, do not directly impact the structural integrity and safety of the scaffold. The focus should always remain on the proper assembly techniques and the physical support required to maintain safety during any work at height.
