![]() ![]() Scaffolds must be tied off to the building or structure at intervals that do not exceed 30 feet horizontally and 26 feet vertically. Adequate mud sills or other rigid footing, capable of withstanding the maximum intended load must be provided. Climbing off the end frames is prohibited unless their design incorporates an approved ladder. Access ladders must be provided for each scaffold. Damaged scaffold members must be removed from service immediately.į. All scaffold members must be visually inspected before each use. All scaffolds must be fully planked and constructed to support the load they are designed to carryĮ. Scaffold planks must be cleated or secured and must extend over the end supports by at least 6 inches but not by more than 12 inches.ĭ. Scaffold planks must be at least 2 x 10 inch full-thickness lumber, structural grade, or the equivalent.Ĭ. If work is to be performed on the scaffold and/or adjacent hazard warrants, guardrails are required at lesser heights.ī. Guardrails shall be 36" to 42" high above the floor or platform. Where this is not possible, sound 2 x 4 inch lumber must be used for the guardrails and midrails and 1x 4 inch lumber for the toeboards. This guardrail system should be constructed from components furnished by the manufacturer. Guardrails, midrails and toeboards must be installed on all open sides of scaffolds 10 feet or more in height. To avoid the use of makeshift platforms, each job should be carefully planned to assure that scaffolding is used when required and that such scaffolding conforms to the applicable regulations.Ī. Scaffolds should be designed, built and inspected by competent persons. (This section would not apply to workers manually moving a scaffold.Inadequate scaffolding is responsible for many construction accidents. When using a power system to move the scaffold, the forces must be applied directly to the wheels. Since the force being applied to the scaffold is less than 5 feet from the ground level, this is acceptable as long as it is the lowest point practicable. The worker holds onto something overhead and moves the scaffold with his or her feet. Your letter describes a worker standing on a Baker scaffold that is 2 to 4 feet high. When manually moving the scaffold, the force should be applied as close to the base a practicable, but not more than 5 feet (1.5 m) above the supporting surface. These sections address the manual and powered forces used to move the scaffold. You asked for clarification on Sections and. Where these conditions are met, the scaffold may be moved while employees are on it. Section specifies the requirements for riding a scaffold. If a device were installed to permit the casters to be locked while on the scaffold, this requirement could be met without dismounting. Section 1926.452(w)(2) requires the casters and wheels to be locked when in use. We apologize for the delay in this response.īaker scaffolds, sometimes referred to as Perry scaffolds, are covered by the mobile scaffold Section of Subpart L. Your questions related specifically to Baker style scaffolds and whether a person could move and work from this type of scaffold, without dismounting, with the casters in the unlocked position. Roy Gurnham and myself, asking for a clarification of OSHA's mobile scaffold standard §1926.452(w). This is in response to your letters, dated June 12, 1997, addressed to Mr. ![]()
