Scaffolds offer many advantages over ladder-jack assemblies whether you are changing sky-high warehouse light bulbs or replacing windows on a two-story home. Framed scaffolds or pipe scaffolds provide a wider platform working surface, can be moved without disassembly, and feature guardrails to keep you from falling. Here’s how to safely use scaffolds to get things done off the ground.
- Make sure you are trained properly to set up scaffolding.
- Check location for ground conditions, overhead wires, obstructions, changes in surface elevation, and tie-in problems.
- Inspect frames, braces and all other components for damage, bends and excessive rust or wear.
- Use a safety harness which is tied off to the scaffold, building or lifeline.
- Assemble frame scaffolds with one other person so that one person is on the scaffold and one is passing materials from the ground.
- Check for squareness and alignment of all scaffold parts.
- Remove debris and mud from the setup area, and level the ground before placing the staging legs.
- Setup the staging legs on a stable, solid base. Use mudsills when scaffolding is erected on soil.
- Use appropriate mud sills that are continuous under at least two support feet.
- Nail or screw the base plates to the mudsills.
- Use jackscrews to eliminate hazards created by temporarily jacking up the erected scaffold to add shims when sections settle or are not level.
- Inspect locking devices frequently.
- Make sure all sections of the first level are level and square.
- Install ladders as the erection proceeds. When scaffolds are to be in place for an extended period, install a stairway. Ladders must extend 1 m (3 ft) above the platform and be tied securely to the staging.
- Fasten all braces and guardrails securely. Make sure all cross bracing fits and locks onto each post in every section.
- Install all of the guardrails that are required: top, mid and toe. Requirements will vary depending on the materials used, and on the the legislation that applies in your area.
- Inspect planks before use. Check the weight the planks will have to carry, including the weight of the crew, tools and materials.
- Complete platform fully at each working level before assembling the next level.
- Secure the scaffolding to the adjacent building structure as specified in the legislation that applies in your area.
- Assemble all equipment according to manufacturer’s specifications or engineer’s design.
