OSHA requires 6″ but many contractors opt for 12″. The only difference is how much lap you feel comfortable with. 9′ and 8′ boards cover a single 7′ span.12′ boards are used to cover a single 10′ span and provide a foot of lap on each side.The extra length ensures these boards stay in place better and allow you to construct the work platform faster. Use these boards whenever a long work platform is needed. What Length Should Your Scaffold Planks Be?ġ6′ boards will cover two 7′ spans. 1 DI65 pine and are tested by an independent agency to make sure they meet or exceed OSHA’s deflection standards under medium duty (50 lbs./sq. OSHA has strict requirements on how much the boards can deflect under a load. You can’t just buy some boards from the lumber yard and expect them be OSHA compliant. They have to be the correct size to fit the span between the frames. They have to be strong enough to support your crew, equipment and materials. Scaffold planks or scaffold boards are a big deal. Our scaffold boards are stamped to show they have been inspected and meet or exceed OSHA standards. They are inspected by an independent agency to make sure they meet or exceed OSHA’s board and deflection standards under medium duty (50 lbs./sq. All wood bearers shall be reinforced with 3⁄16 x 2 inch steel strip, or the equivalent, secured to the lower edges for the entire length of the bearer.Our 10" X 2" scaffold boards are made from high-quality yellow pine. NOTE: All members except planking are used on edge. Maximum vertical spacing of horizontal members Note: Platform units used to make scaffold platforms intended for light-duty use shall be capable of supporting at least 25 pounds per square foot applied uniformly over the entire unit-span area, or a 250-pound point load placed on the unit at the center of the span, whichever load produces the greater shear force. 250 pounds placed at the center of the span and 250 pounds placed 18 inches to the left and right of the center of the span (total 750 pounds).250 pounds placed 18 inches to the left and right of the center of the span (total 500 pounds).250 pounds placed at the center of the span (total 250 pounds).75 pounds per square foot applied uniformly over the entire span area.50 pounds per square foot applied uniformly over the entire span area.25 pounds per square foot applied uniformly over the entire span area.Masons' multi-point adjustable suspension scaffolds.įabricated planks: Maximum intended load being calculated Rated load.Stonesetters' multi-point adjustable suspension scaffolds.Two-point adjustable suspension scaffolds.Single-point adjustable suspension scaffolds.Step, platform and trestle ladder scaffolds.Form scaffolds and carpenters' bracket scaffolds.Plasterers', decorators' and large area scaffolds. Scaffold components which are not selected and loaded in accordance with this Appendix, and components for which no specific guidelines or tables are given in this appendix (e.g., joints, ties, components for wood pole scaffolds more than 60 feet in height, components for heavy-duty horse scaffolds, components made with other materials, and components with other dimensions, etc.) must be designed and constructed in accordance with the capacity requirements of § 1926.451(a), and loaded in accordance with § 1926.451(d)(1). However, the guidelines do not provide all the information necessary to build a complete system, and the employer is still responsible for designing and assembling these components in such a way that the completed system will meet the requirements of § 1926.451(a). An employer may use these guidelines and tables as a starting point for designing scaffold systems. This appendix provides non-mandatory guidelines to assist employers in complying with the requirements of subpart L of this part.
