To ensure scaffolding safety, the scaffold must be built under the supervision of a competent person, and workers must be trained by a qualified person before they use the scaffold. 11. The scaffolding selected must be able to withstand this load (the safety factor of four is designed into the rated load capacity). Install ties as close as practicable where horizontal members connect to vertical legs. If you see such a situation, do not get on that scaffold. For example, a design specifying an unusual base structure that has to be erected to support the scaffold may introduce unique hazards and risk controls. Scaffold structures should not be tied to newly built masonry structures until the mortar joints have cured sufficiently to withstand the loads and structures have adequate stability. 16. Following are some basic guidelines for workers who use scaffolds: This article originally appeared in the August 2007 issue of Occupational Health & Safety.

Scaffolds 3 ft. and narrower must be tied at vertical intervals no more than 20 ft. apart. Scaffolding safety is a set of preemptive actions in building, inspecting, using, and tagging scaffolds. When a crosspoint of crossbracing is used as a midrail, it must be between 20 inches (0.5 meters) and 30 inches (0.8 m) above the work platform. • Other scaffolds, principally man lifts, cherry pickers, scissor lifts, etc., are sometimes thought of as vehicles or machinery but can be regarded as another type of supported scaffold. Tie-in requirements may increase if heavy wind loads are anticipated. How much load should all suspension scaffold support devices be capable of supporting? Scaffold and scaffold components shall not be loaded in excess of their maximum intended load or rated capacity, whichever is less. (Think about it) Fall restraint; you don’t want to come out of the basket due to the cantilever effect. In some cases, it may no be feasible or practical to tie off the scaffolding such … Common types of supported scaffolds are frame, system, mobile (rolling), etc. Maximum horizontal distance between ties is not to exceed 30’.

OSHA competent person and green card requirements. • Supported scaffolds, which consist of one or more platforms supported by rigid, load-bearing members, such as poles, legs, frames, outriggers, etc. The scaffolding plan should include information about the position of the check couplers. Ties must be placed as near as possible to horizontal members. Scaffold should be erected as close as practicable to the working face. This is achieved by following the guidance provided by the NASC in document SG4 ‘Preventing falls in scaffolding’ for tube and fitting scaffolds or by following similar guidance provided by the manufacturers of system scaffolding. Scaffold components of dissimilar metal… The most important preventative measures are training and education, proper selection of equipment, and proper use of equipment. F. WHEN SCAFFOLDS ARE FULLY OR PARTIALLY ENCLOSED, or when scaffolds are subjected to overturning forces, additional ties may be required; consult a qualified person. Preventing Scaffolding Accidents not greater than 26 feet. The top tie shall be installed as clos e to the top of the platform as possible; however, no lower from the top than 4 times the scaffold’s minimum base dimension. unless a specific engineering design is provided, fix the first row of ties no more than 4 … 12 iron wire, or single looped No. Where written confirmation from a competent person is required a new handover certificate should be provided. Overturning or tipping … Appropriate fall protection may be required by the competent person for such activities or where the scaffolding is considered incomplete (i.e. not ropes or straps) to a suitably strong and secure adjacent structure. The OSHA scaffold standard states "guys, ties, and braces shall be installed at locations where horizontal members support both inner and outer legs". The legs, poles, frames, and uprights shall bear on base plates and mud sills. Installation of ties and braces must be done in a workmanlike manner. capable of transferring the tensile and compressive loads involved. Generally, that will require ties at least at 4m height intervals. 14901 Quorum Drive, Suite 425 Each scaffold and scaffold component shall be capable of supporting, without failure, its own weight and at least four times the maximum intended load applied or transmitted to it. Keys to reducing accidents are education, proper selection, and proper use of equipment.
