Rowlett, TX 75088, Non-Stop Scaffolding Individual Parts and Accessories, OSHA Scaffolding Requirements – Tie Off Locations. Scaffolding safety is a set of preemptive actions in building, inspecting, using, and tagging scaffolds. Loads arising from fall arrest events should be considered by the scaffold designer for which useful references include SG4 and BS EN 795 and BS 7883. The tower must be tied with sufficient suitably strong rigid two-way ties (i.e. Scaffold should be erected as close as practicable to the working face. What is Scaffolding Safety? not ropes or straps) to a suitably strong and secure adjacent structure. Footings, sills or supports must be capable of supporting at least 2 times the maximum load to which they are subjected without settlement. Need some tips for conducting an incident investigation at work after there’s been an occupational injury or illness, or maybe even a near miss? Are you prepared? unless a specific engineering design is provided, fix the first row of ties no more than 4 … 10 feet Each scaffold must be capable of supporting, without failure, it's own weight and at least 4 times the maximum intended load applied or transmitted to it. 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. Preventing Scaffolding Accidents Scaffold and scaffold components shall not be loaded in excess of their maximum intended load or rated capacity, whichever is less. – Avoid the following unsafe practices: •Lean-to scaffolds ... Scaffold frames must never be spaced wider than 10 feet apart. The most important preventative measures are training and education, proper selection of equipment, and proper use of equipment. Ties must prevent the scaffold from tipping either into or away from the structure. not greater than 26 feet. Check the following before using scaffolding and inspect on an adequate basis: the base is sound, level and adjusted, legs are plumb and all braces are in place, locking devices and ties are secured, cross members are level, planks are of the proper grade(s) of lumber and have no weak areas, deterioration, or cracks. In 2004, approximately 400,000 workers suffered construction-site injuries. Additional, accidental, loads are not covered.

All scaffolding must be erected, dismantled and altered in a safe manner. Scaffold components of dissimilar metal… According to OSHA, nearly 65 percent of workers in the construction industry work on scaffolds frequently. Wire or fiber rope used for scaffold suspension shall be capable of supporting at least six times the intended load. If an inspection identifies a problem with the scaffold, access to the scaffold must be controlled and any necessary repairs, alterations and additions completed. Where possible, push/pull ties should be used, ensuring that the tie tube is connected to both frame legs with right angle clamps.
