Wooden platforms (i.e. [, Fall protection consists of either personal fall arrest systems or guardrail systems meeting OSHA requirements. Critical to scaffolding safety are the use of competent persons for the design, erection/dismantling, and maintenance of scaffolds, and trained workers for their use. It is not all-inclusive and should be used as a starting point for the competent person to develop a checklist specific to the type of scaffold and jobsite conditions encountered. It's best to have everything as low as possible so parts don't get blown or bounced out. [, Scaffold components manufactured by different manufacturers are not allowed to be modified to make them fit together, unless a competent person determines that the resulting scaffold is structurally sound. He suffered multiple fractures to the head, left and right foot, and left wrist, and torn ligaments in the knees. 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). Changes at the worksite present a hazard for which an employee has not previously been trained. Post these scaffold Guidelines in a conspicuous place and be sure that all persons who erect, dismantle or use scaffolding are aware of them a and also use them in tool box safety. (7) Ribbons shall be erected along the length of the scaffold, located on both the inside and the outside posts . In general, a level is the easiest way to achieve the desired right angles. 1 . Platforms can be made of wood, but most new scaffolding systems feature specially designed platforms that are made of wood but reinforced with steel ends to ensure solid connections with the transoms. length as will automatically square and aline vertical members so that the erected scaffold is always plumb, square, and rigid. must be plumb and braced to prevent swaying and displacement. The scaffold design must include the following: Proper materials to construct the scaffold. Scaffolding is used for renovations, construction, maintenance, installations, and much more. Workers building scaffolds risk serious injury from falls and tip-overs, being struck by falling tools and other hazards and electrocution from energized power lines. the diagonal brace to keep the scaffolding square. Attach tags at the access point of the scaffold. Haul Scaffolding Safely. [, Portable, hook-on, and attachable ladders must be positioned so as not to tip the scaffold. Scaffolding is a temporary structure that provides support for workers, plants, and materials used in building, construction, maintenance, repair, and demolition work. For example, if the base width is 5 feet, the first vertical tie will be (5 feet x 4) 20 feet from the ground. The momentum of the frame thrust the employee backward off the second level. [, A landing platform at least 18 inches wide by 18 inches long at each level. [, Be positioned so that their bottom step is not more than 24 inches above the scaffold supporting level, [, Have rest platforms at maximum vertical intervals of 12 feet, [, Have a minimum step width of 16 inches, except for mobile scaffold stairway-type ladders, which shall have a minimum step width of 11 inches [, Have slip-resistant treads on all steps and landings. Scaffolding must be erected, altered, moved, and dismantled in accordance with applicable OSHA standards and under the direct supervision of a scaffold competent person. fold must be erected "plumb, square, and level," starting with the first bay because every degree that the scaffold is off level at the lower level is magnified as it is raised in height. 5. Platforms may be coated periodically with wood preservatives, fire retardants, and slip-resistant finishes, provided they do not obscure the top or bottom wood surfaces. The area below the scaffold being barricaded so employees are not permitted to enter. For example, if wrapped with mesh, will the scaffold support expected wind loads? [, OSHA standards specifically forbid climbing cross-braces as a means of access. Personal fall arrest systems used on scaffolds are required when the guardrail system is incomplete or does not provide adequate protection. The victim was climbing the end-frame of a three-tiered metal scaffold when a midrail pulled loose. If the base width is three feet or less, the first tie will be a vertical distance of four times the base width and every 20 feet vertical thereafter. The maximum extension for a screw jack is 18 inches high. Since it is an elevated platform, the stability decreases as the height increases. The amount of time needed to erect and dismantle the scaffold. Because the frames are stacked, the cross braces have to keep the scaffold plumb, level, and square. PLUMB/LEVEL/SQUARE.
