Which of the following is designed to enhance the safety of platform use in scaffolding?

The correct choice is cleating the platform on the bottom. This method of securing the scaffold platform involves using cleats or other anchoring devices to stabilize the platform and prevent it from shifting or sliding while in use. This is crucial because a stable platform is essential for the safety of workers who rely on it for access to height and for performing various tasks.

By cleating the platform, it reduces the risk of sudden movements that can lead to falls, as a loose platform may not provide reliable footing. Properly installed cleats keep the platform securely in place, which is a vital aspect of ensuring safety in scaffolding practices. The implementation of this safety feature contributes significantly to minimizing accidents and injuries in construction environments.

While other options involve safety considerations, they do not directly address the stability of the platform itself to the same extent as cleating does.
