Question: A carpenter is working from a fully assembled and inspected mobile scaffold tower that is 6 metres high. The scaffold is equipped with castor wheels. Before moving the scaffold to a new position along the building wall, what critical safety step must be performed?

Answer options:

• Ensure all tools are on the platform to avoid multiple trips. ✅ Verify that no one is on the scaffold platform at the time of movement.
• Lower the platform to the lowest possible height to improve stability.
• Remove all bracing and outriggers to facilitate easier movement.

Correct answer: Verify that no one is on the scaffold platform at the time of movement.

Explanation: According to safety regulations (e.g., CSA Z797), a mobile scaffold must not be moved while any person or materials are on the platform, as this creates a significant risk of overturning, particularly for higher scaffolds. Lowering the platform might improve stability, but the primary rule is to clear the platform.
