Do not force frames or braces to fit - level the scaffold until proper fit can easily be made. [, Have uniform spacing between rungs of a maximum 16 inches. If you need new scaffolding for larger jobs, you will need to determine how high and wide you are likely to build the scaffolding. The planking used must be "scaffold grade.". Scaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other man-made structures.Scaffolds are widely used on site to get access to heights and areas that would be otherwise hard to get to. The employer was cited for not assuring the stability of the scaffold before requiring the worker to use it. Do not force frames or braces to fitlevel the scaffold until proper fit can easily be made. All joints must be Appropriate fall protection may be required by the competent person for such activities or where the scaffolding is considered incomplete (i.e. [, Have minimum rung length of 11 inches.
