When the height to base width ratio of a scaffold exceeds the established limit, there is a significant concern regarding stability and the potential for tipping over. In this scenario, the scaffold must be restrained to ensure it remains stable while in use. Proper restraint methods may include the use of guys, ties, or braces, which help anchor the scaffold and prevent any movement that could lead to tipping.

This requirement is in place to uphold safety standards and protect workers from falls or accidents that could arise from an unstable scaffold. Neglecting to restrain an excessively tall scaffold can lead to catastrophic failures, hence the importance of ensuring that scaffolds are adequately supported in accordance with OSHA regulations and guidelines.
