When erecting scaffolding on an uneven surface, using screw jacks to level the structure is the most effective and safe practice. Screw jacks are specifically designed to adjust the height of the scaffold legs, allowing for fine-tuning to ensure the scaffolding is stable and level across varying terrain. This method provides a secure base, reducing the risk of movement or tipping, which can occur if the scaffold is not properly leveled.

Other practices, such as using wood blocks, might seem like a solution, but they can compress or shift over time, potentially leading to instability. Similarly, welding on leg extensions is not a standard or recommended approach since it can compromise the integrity of the scaffold and is generally not permissible under safety regulations. While using extra caution is always advised when working with scaffolding, it does not replace the necessity for proper leveling techniques, such as those provided by screw jacks, which ensure that the scaffold remains safe and effective for use.
