Why it matters

Rolling scaffolds like Baker units are all over drywall, paint, and ceiling work. They tip when a wheel drops into a floor box, when someone pushes from the top, or when a worker rides it across a floor that is not level.

The talk

Interior crews love the rolling scaffold. It sets up quick, fits through doors, and saves climbing a ladder a hundred times a day. But it is a narrow platform on small wheels. Most bad days start with something small. A wheel is not locked and the platform drifts when you push on the ceiling. A caster drops into an open floor box or off the edge of a slab. A worker stands on the guardrail or a bucket to reach higher. Or somebody rides it while a buddy pushes, and a wheel catches on a cord.

The rules are not complicated. The scaffold must be braced, plumb, level, and square, with all the pins in. Lock the casters every time you are working from it. When you move it, push near the base, never more than 5 feet up. Riding a rolling scaffold is only allowed when a strict list is met. The floor is within 3 degrees of level and clear of holes and junk. The scaffold is no taller than two times its base width, unless it is built for more. Outriggers, if used, are on both sides. Nobody stands out past the wheels. On most jobs it is simpler to get off, move it, and climb back up.

Height changes things too. If the platform is more than 10 feet above the floor below, you need fall protection, which on these units usually means guardrails all the way around. Use the built-in ladder or an attached ladder to get up, not the cross braces. Level the unit with its screw jacks, not with scrap blocks under the wheels. Keep the platform clear of buckets and loose screws. Before you roll it anywhere, walk the path. Look for floor boxes, cords, ramps, door thresholds, and edges. If a wheel sinks or catches, stop and fix it. Do not jerk it free with someone on top.

Key points

  1. Lock every caster before you work from the platform.
  2. Keep it braced, plumb, level, and square, with all pins in.
  3. Push near the base, no higher than 5 feet.
  4. Get off before it moves unless every riding condition is met.
  5. Over 10 feet up, you need fall protection like full guardrails.
  6. Climb the ladder, not the cross braces.
  7. Walk the path before you roll it.

Do this

  • Check the wheel locks each time you stop.
  • Level it with the screw jacks.
  • Climb up on the built-in or attached ladder.
  • Keep tools and buckets away from the platform edges.
  • Cover or mark floor boxes and holes on the path.

Do not do this

  • Do not ride it while someone pushes unless every riding rule is met.
  • Do not stand on the guardrail, a bucket, or a stepladder on the platform.
  • Do not push or pull it from the top.
  • Do not shim the wheels with scrap blocks.
  • Do not jerk it free when a wheel is stuck with someone on it.

Talk about it

  1. What is on the floor between here and the next room that could catch a wheel?
  2. Which of our rolling scaffolds go over 10 feet, and do they have full rails?
