(See “Multi-point adjustable suspension scaffold”.)Ĭleat means a structural block used at the end of a platform to prevent the platform from slipping off its supports.
Additional support may be provided by vertical pickups.Ĭhimney hoist means a multi-point adjustable suspension scaffold used to provide access to work inside chimneys. Adjustable suspension scaffold means a suspension scaffold equipped with a hoist(s) that can be operated by an employee(s) on the scaffold.īearer (putlog) means a horizontal transverse scaffold member (which may be supported by ledgers or runners) upon which the scaffold platform rests and which joins scaffold uprights, posts, poles, and similar members.īoatswains' chair means a single-point adjustable suspension scaffold consisting of a seat or sling designed to support one employee in a sitting position.īody belt (safety belt) means a strap with means both for securing it about the waist and for attaching it to a lanyard, lifeline, or deceleration device.īody harness means a design of straps which may be secured about the employee in a manner to distribute the fall arrest forces over at least the thighs, pelvis, waist, chest and shoulders, with means for attaching it to other components of a personal fall arrest system.īrace means a rigid connection that holds one scaffold member in a fixed position with respect to another member, or to a building or structure.īricklayers' square scaffold means a supported scaffold composed of framed squares which support a platform.Ĭarpenters' bracket scaffold means a supported scaffold consisting of a platform supported by brackets attached to building or structural walls.Ĭatenary scaffold means a suspension scaffold consisting of a platform supported by two essentially horizontal and parallel ropes attached to structural members of a building or other structure. The criteria for aerial lifts are set out exclusively in § 1926.453. It does not apply to crane or derrick suspended personnel platforms. This subpart applies to all scaffolds used in workplaces covered by this part. Finally, the language of the rule was simplified, duplicative and outdated provisions were eliminated, overlapping requirements were consolidated, and the performance orientation of the rule was enhanced to allow employers as much flexibility in compliance as is consistent with employee protection.§ 1926.450 Scope, application and definitions applicable to this subpart. Another area that the final rule strengthens is training for workers using scaffolds the conditions under which such employees must be retrained are also specified in the final rule.
In addition, the final rule allows employers greater flexibility in the use of fall protection systems to protect employees working on scaffolds and extends fall protection to erectors and dismantlers of scaffolds to the extent feasible. In particular, the final rule was updated to address types of scaffolds - such as catenary scaffolds, step and trestle ladder scaffolds, and multi-level suspended scaffolds - not covered by OSHA's existing scaffold standards. The final rule updated the existing scaffold standards and sets performance-oriented criteria, where possible, to protect employees from scaffold-related hazards such as falls, falling objects, structural instability, electrocution and overloading. The Occupational Safety and Health Administration (OSHA) revised the construction industry safety standards which regulate the design, construction, and use of scaffolds.
