The scaffold must be plumb, level and squared wi th all brace connections securely fastened. Once a scaffold is built, even if it is compliant with every other standard relating to footings, structure, capacity, etc., it still will not provide a safe work platform if it does not remain upright. Shapes materials to prescribed measurements, using saws, chisels, and planes. Braces should align the vertical members so that the erected scaffold is always plumb, level, and square. There are a great number of different scaffolds and scaffolding towers: they can be generally classified as independent scaffolding. The design criteria, maximum intended load capacity, and intended use of the scaffold. Click here to learn more about Scaffolding Regulations.

Duty level of scaffold is based on the chart below. [, Ends of rails may not extend beyond their terminal posts, unless they do not constitute a projection hazard to employees. Workers building scaffolds risk serious injury from falls and tip-overs, being struck by falling tools and other hazards and electrocution from energized power lines. Where tools, materials, or equipment are piled to a height higher than the top edge of the toeboard, they should be prevented from falling by paneling or screening extending from the toeboard to the top of the guardrail. Supported scaffold poles, frames, uprights, etc. A scaffold can be overloaded by [. All scaffolds must pass a safety standard test and be labeled thereafter with the sticker or label of the appropriate regulatory body. To accomplish this, the scaffold design must incorporate a realistic assessment of maximum intended loads on the scaffold at all stages of erection and loading. Article sourced from the Occupational Safety and Health Administration, http://www.OSHA.gov. [, On scaffolds where platforms are abutted to create a long platform, each abutted end must rest on a separate support surface (this does not preclude the use of shared support members such as "T" sections, hook-on platforms that rest on common supports, etc.).
