What is a potential danger of not using the correct tie spacing in scaffolding?

Using the correct tie spacing in scaffolding is crucial for maintaining the structural integrity and safety of the scaffold. When ties are spaced incorrectly, the scaffolding may lack sufficient support, which can lead to instability. This instability increases the risk of the entire structure collapsing under weight or during movement, posing a significant danger to workers and anyone nearby. Adequate tie spacing helps to distribute loads evenly and provides the necessary bracing to ensure that the scaffold can withstand the forces acting on it, such as wind or the weight of workers and materials.

Other concerns, like increased manual handling tasks or difficulty accessing work areas, might affect efficiency or convenience, but they do not pose an immediate danger to safety in the same way that an unstable or collapsing scaffold does.
