(Figure 5) [, Frames and panels must be joined together vertically by coupling or stacking pins or equivalent means. For example, if wrapped with mesh, will the scaffold support expected wind loads? Changes in the types of scaffolds, fall protection, falling object protection, or other equipment present a hazard for which an employee has not previously been trained. For lathing and plastering, a gap of 18 inches is permitted. A specific access, such as a mounted ladder, must be used. Guardrails May Have Saved Him, Occupational Safety and Health Administration, Outreach Training Program (10- and 30-hour Cards), OSHA Training Institute Education Centers, Electrical Incidents: Lack of Ground-Fault Protection, Severe Storm and Flood Recovery Assistance, Scaffolding : Supported Scaffolds - Frame or Fabricated, In order to assure stability, supported scaffolds must be set on [, Footings must be capable of supporting the loaded scaffold without settling or displacement. The competent person should use this checklist for daily inspections of the scaffold. To be specific, a "true" surface is as "plumb" or as "level" as the job requires (which, in most cases, is a perfect level of both or either). Suspension scaffold rigging must at least 6 times the intended load. The ladder must extend 1 m (3 ft.) above the landing. Most screw jacks will have a built-in stop so that the maximum height cannot be exceeded. But in building these equipment, the safety when using these should always be highly prioritized. Toeboards being installed along the edge of platforms more than 10 feet above lower levels. Each frame or panel shall be braced by horizontal bracing, cross bracing, diagonal bracing or any combination thereof for securing vertical members together laterally. The proper use of the scaffold, and the proper handling of materials on the scaffold. Where the platform will not be more than 14 inches from the face of the work (18 inches for plastering and lathing operations), fall protection is not required. Don't use bricks, blocks, barrels, or other unstable objects to level a scaffold. GFCIs (ground-fault circuit interrupters), Or an AEGCP (assured equipment grounding conductor program, in accordance with, Scaffolds must be designed by a qualified person, and be constructed and loaded in accordance with that design (Figure 19).
