Before moving a mobile scaffold, the key conditions are that the route and ground are safe and level, the scaffold is stable, and no one is exposed to uncontrolled movement risks.

Core safety conditions

  • The surface must be firm, level (typically within about three degrees of level), and free of pits, holes, debris, and other obstructions that could cause wheels to catch or the scaffold to tip.
  • The path of travel must be checked in advance for hazards such as power lines, overhead obstructions, and uneven ground or openings.
  • The scaffold must be structurally complete, stable, and not overloaded, with any required outriggers or stabilisers correctly fitted if needed for height-to-base ratio.

Conditions while it is being moved

  • The manual force used to move the scaffold should be applied as close to the base as practicable and not more than about 5 feet above the supporting surface to reduce tipping risk.
  • Movement speed should be controlled and slow (some guidance suggests not faster than about 1 foot per second when powered), avoiding sudden starts, stops, or changes of direction.
  • If anyone is allowed to ride on the scaffold during movement (which many safety guides advise avoiding), strict criteria must be met: workers must be aware of the move, the surface must be level and unobstructed, the scaffold must be within the permitted height-to-base ratio, and any outriggers must be installed.

Common “must nots”

  • Do not move the scaffold in high or gusty winds, especially outdoors, because wind can significantly increase tipping risk.
  • Do not move a scaffold over unfinished, very rough, or sloping surfaces unless specific stabilizing measures are in place and this is allowed by the design and procedure.
  • Do not move the scaffold if components are damaged, not properly secured (such as unlocked casters when in use or unpinned wheels), or if there is any sign of instability.

Typical exam-style answer (for “which conditions must be met?”)

In many training or exam questions, the correct choices are usually along the lines of:

  • Ground/route checked and level, clear of obstructions and holes.
  • Scaffold complete, stable, within safe height-to-base ratio, with stabilisers/outriggers fitted if required.
  • No hazardous overhead obstructions or power lines in the path.
  • Movement force applied near the base, at a controlled speed.
  • Workers either not on the scaffold during movement, or riding only when all specified safety criteria are met.

These capture the essential conditions that should be met before moving a mobile scaffold in line with common safety guidance and regulations.
