Failing to install the Locking pin to secure the wheels in place, because one of the wheels fell out when the scialfa was rolled over a depression in the ground, height of a rolling scaffold may not exceed three times the base dimensions use Outriggers increase base dimensions and allow for higher free-standing scaffold. It's like attachments that add additional legs.

If the height of a platform exceeds two times the minimum base dimensions on a rolling scaffold can a worker stay on the platform?

No, the worker may stay on the platform if it's only one and a half times the minimum base dimensions of the rolling scaffold. If the height of the work platform is less than one and a half times the minimum base Dimension a worker on the platform a reposition the platform.
