When using rolling scaffolding, there are several key safety requirements to ensure the safety of workers:

1. Height Restrictions: The height of a rolling scaffold should not exceed three times the smallest base dimension, or if outriggers are used, the smallest base dimension including the extended outriggers [1].

2. Stability: Outriggers, if provided, must be firmly attached to the scaffold uprights to ensure stability. Each wheel on a rolling scaffold must be equipped with a device to securely attach the wheel to the scaffold, and the scaffold must be secured against inadvertent movement while a worker is on it [1].

3. Movement: Workers should not remain on a rolling scaffold while it is being moved unless specific conditions are met, such as the height of the work platform not exceeding twice the shortest base dimension, and the route being free of any conditions that could cause the scaffold to tilt or go out of control [2].

4. Inspection: The scaffold should be inspected before each day's use by a competent person and by the person who is to use the scaffold [3].

5. Wheel Locking: Rolling scaffolds must have lockable wheels that are locked while the scaffold is in use [4].

6. Platform Coverage: The work platform should fill the entire area enclosed by the scaffold structure [2].

By adhering to these guidelines, you can help ensure the safe use of rolling scaffolds in the workplace.
