Scaffolding eTool

Supported Scaffolds

Supported scaffolds consist of one or more platforms supported by outrigger beams, brackets, poles, legs, uprights, posts, frames, or similar rigid support. Because frame scaffolds are the most common type of supported scaffold, this eTool uses the frame module to describe requirements that are common to all supported scaffolds. Requirements specific to the other scaffold types are described only in their respective modules.
