Scaffolding safety work platform. In all circumstances where it is possible to provide platform widths as listed below then the stated dimensions should be maintained.
Scaffolding safety work platform
- If for reasons of limited space, it is not possible to provide such widths, then that platform should be as wide as the space permits.
- Minimum widths of platforms should be as follows:
- At least 3 boards 600mm – for persons only and not for the deposit of materials.
- At least 4 boards 800mm – for persons and deposit of material leaving a clear passage of at least 430mm.
- At least 5 boards 1.05m – if used to support any higher platform.
- At least 6 boards 1.30m – if used by persons to dress or shape stone.
- At least 7 boards 1.50m – if used by persons to dress or shape stone, and to support their trestle platforms.
- When work has to be done at the end of a wall or other structure, then the working platform should extend at least 600mm beyond this point.
- The working platform should be placed as close to the face of the structure as possible.
- All scaffold platforms should be closely boarded.
- Scaffold boards should be free of large splits and knots and should be banded at both ends and not cut in any way.
- No board should overhang its last support by more than 4 times its thickness but should have a minimum overhang of 50mm.
- Any group of boards across the width of a scaffold should be of the same length and thickness.
- The spacing of board supports (transoms) should be as follows:
38mm thick boards – 1.5m maximum centers
50mm thick boards – 2.6m maximum centers
63mm thick boards – 3.25m maximum centers
- Scaffold boards should normally have at least three supports.
- 38mm thick boards less than 2.13m long should not be used unless they are fixed down to prevent tipping.
- Boards less than 1.8m long may be supported on two transoms but should be fixed down at both ends. Scaffolding safety work platform
- Scaffold boards should be laid so that there is no trip hazard created.
- Where any possibility of displacement exists from high winds, boards should be fastened down. See also Scaffolding parts name
- Where platforms become slippery due to frost, snow, mud, etc., the boards should either be cleared or turned over.
- Every scaffold platform from which a person can fall should be fitted with guardrails and toe boards. See also Scaffolding safety checklist
- Where any other risk of injury exists i.e. falls onto starter bars, such platforms should be similarly protected.
- Guardrails and toe boards are required at the outsides and ends of all working platforms, and on the insides.
- if gaps exceeding 300mm have been left for working at the face of a building or structure. See also Working at heights procedure
- Toeboards and guardrails should be fitted on the inside of standards to prevent outward movement.
- Toeboards should rise at least 150mm above the working platform.
- Guardrails should be not less than 950mm, nor more than 1.15m above the working platform.
- Middle guardrail must be 470mm from the working platform.
- Where a fall risk position exists or is identified, safety harnesses must be utilized and training must be provided.
