List three control measures used to minimize risks associated with mobile scaffolds?

The correct answer emphasizes vital aspects of scaffold safety that help to mitigate risks associated with mobile scaffolds. Using braces enhances the structural integrity of the scaffold, providing stability and preventing collapse, which is crucial when the scaffold is moved frequently. Suitable access ensures that workers can safely reach the work area without risking falls or accidents, promoting safer working practices while using the scaffold. Avoiding sloping ground is essential as it helps prevent instability; scaffolds should be placed on level surfaces to minimize the risk of tipping or sliding.

The combination of these measures is critical in maintaining a safe working environment. Each measure complements the others, reinforcing safety protocols in scaffold use. In contrast, other options might include factors that do not address the core structural and access-related issues that mobile scaffolds face, or they might represent general safety practices not specific enough to the unique challenges presented by mobile scaffolds.
