OSHA 10-Hour - Module 5
The first step in building a scaffold includes a site inspection to: - ANSWER-1. Identify site-specific hazards not identified in the preplanning stage, and
2. Ensure that the specific characteristics of the site are considered in the scaffold design.
What is true about building a scaffold? - ANSWER-- Builders must have a means of safe access.
- Using cross-braces for access is not permitted by the OSHA standard
What must builders do before they can permit the use of a scaffold? - ANSWER-Fall protection systems and falling object protection must be installed on any scaffold more than 10 feet above a lower level.
Supported scaffolds - ANSWER-These are comprised of one or more platforms supported by outrigger beams, brackets, poles, legs, uprights, posts, frames, or similar rigid supports.
Suspension scaffolds - ANSWER-These are comprised of one or more platforms suspended by ropes or other non-rigid means from an overhead structure.
Aerial lifts - ANSWER-These are vehicle mounted devices such as cherry pickers or boom trucks used to get a worker to an elevated position.
Fabricated Metal Frame Scaffolding - Design - ANSWER-Uses cross braces to connect prefabricated frames together. The size of the frames, as well as the length and type of the planks laid between them, dictate the max. load possible.
Fabricated Metal Frame Scaffolding - Use - ANSWER-- Widely used at many jobsites due to simple assembly, rigid construction, low cost, and durability. - Can be erected up to 125 feet in height.
- Available in different configurations and weight ratings to accommodate many types of work such as masonry and plaster work.
Fabricated Metal Frame Scaffolding - limitations/hazards - ANSWER-- Rigid prefabricated construction makes it less adaptable to unusual building shapes than other scaffold types - Fabricated frame scaffolds more than 125 feet high must be designed by a registered professional engineer. - Deenergize, guard, or mark all electrical hazards and keep all conducive materials at least 3 feet from electrical hazards.
- Scaffold frames and panels must be attached together with pins, couplers, or equivalent devices
