A safety base is provided for a scaffold. The scaffold has casters so that it can be moved periodically at the job site. The safety base has two components, each consisting of an elongate bar with adjustable safety legs near the ends, along with detachable locks for readily attaching the component to frame members of the scaffolding. Feet of the legs are positioned near the supporting surface so that if the casters encounter a depression as the scaffold is being moved, the feet will engage the surface and the scaffold will not tilt excessively.
