What is required for a worker's safety when moving a rolling scaffold?

The requirement that the height of the platform must not exceed twice the shortest base dimension is crucial for ensuring a worker's safety when moving a rolling scaffold. This guideline is designed to maintain stability and prevent tipping or toppling while the scaffold is in motion. A scaffold that is too tall in relation to its base can easily become unbalanced, especially when it is being moved, leading to potential accidents or falls.

To further elaborate on the context, maintaining this height-to-base ratio ensures that the center of gravity remains low, which is an essential factor in preventing the scaffold from becoming unstable. This standard is a part of scaffold safety regulations and practices that aim to create a safe work environment.

In contrast, while it might seem reasonable to allow a worker to remain on the scaffold during movement, this can greatly increase the risk of falls or injury. Similarly, securing a worker to the scaffold or lowering the platform to the ground could also be seen as safety measures, but these do not specifically address the inherent stability and safety concerns that come with moving a scaffold. The stability provided by adhering to the height-to-base ratio is a foundational aspect of scaffold safety that directly impacts the worker's protection.
