Scaffolding wood is a safe material to keep in homes. Although it is softwood, scaffolding wood comes in thick planks that make sturdy furniture. If it is not treated with glues, finishes and paints, scaffolding wood can be recycled into engineered wood products or fuel.
Cutting them to length is not a problem since there is no special treatment of the end of these planks. Do use reasonable care in cutting and handling the planks to avoid having any separation of the lamination.
(e) Overhead protection shall consist of 2 inch nominal planking laid tight, or 3/4-inch plywood.
(a) made of No. 1 grade or better spruce or fir.
This wood is selected over wood grown in the UK such as Sitka Spruce and Scotts pine as it is the correct size and has superior structural integrity, which is inherent in the trees genetic make-up. … When the wood arrives from mainland Europe it arrives already cut to the correct dimensions.
Solid-sawn planks The most common wood used for solid-sawn scaffold planks is southern yellow pine, which the Southern Pine Inspection Bureau grades as DI-65 or, less commonly, DI-72.
| Rated load capacity | Intended load |
|---|---|
| Heavy-duty | 75 pounds per square foot applied uniformly over the entire span area. |
| One-person | 250 pounds placed at the center of the span (total 250 pounds). |
| Two-person | 250 pounds placed 18 inches to the left and right of the center of the span (total 500 pounds). |
The Australian Standards for Scaffold Planks (AS 1577 – 1593) provides numerous and very specific compliancy rules when it comes to scaffold planks. It states that each scaffold plank on working platforms should: … Be positioned so there are no gaps between planks which are greater than 10mm, and.
Weight: 64.0 lbs.
OSHA Grade Planks are made of Yellow Southern Pine, Clipped, Rodded and OSHA Stamped. Come in three sizes: 8′, 12′ and 16′ lengths. All planks are 2″ high by 10″ wide and rod and clipped.
The mandatory rule is found in OSHA 1926.451(f)(16) and says a scaffold board cannot deflect more than 1/60th of its length when loaded. This means a board on a 7′ span can deflect up to 1.4″ when fully loaded.
(Emphasis added). The standard requires that the space between the scaffold planks or between scaffold planks and uprights be no more than one inch wide unless the employer can demonstrate that a wider space is necessary. However, the platform must still be planked or decked as fully as possible.
Pinned Plank – A plank made of two or more members (sawn lumber, finger-jointed lumber and/or structural composite lumber) where the members are mechanically fastened together.
Which lumber grading agencies will OSHA accept as a qualified grading agency for inspecting and stamping scaffold grade lumber? Response: OSHA does not require that scaffold planks be graded and stamped by a qualified grading agency. … For your convenience, the current list of certified agencies is enclosed.
Wood, such as fir or pine, is the most common material. High-quality wooden planks, such as Kennison Forest Products solid sawn scaffold planks or sure-lam LVL (laminated veneer lumber) scaffold planks, provide durable, safe planking solutions.
Fungal decay, usually wet rot, is common in poorly stored scaffold boards. Wood is vulnerable to attack when the moisture content is over 20%. It can be detected by discolouration of the wood, which also becomes softer.
They are always warped and twisted… no board is ever the same and they are never the same thickness or depth throughout their length… this is their characteristic because they were never sawn in the timber mills to be made into furniture… … Remnants of paint the scaffolding company use to identify their boards…
The reclaimed scaffolding boards we use are made of European Whitewood (sometimes referred to as silver fir or Norway spruce). European Whitewood is is a medium density soft wood which is low in weight. It is sturdy and long lasting and therefore suitable for load baring uses, hence the use as scaffolding boards.
The Occupational Safety & Health Standards Board, a seven-member body appointed by the Governor, is the standards-setting agency within the Cal/OSHA program. The Standards Board’s objective is to adopt reasonable and enforceable standards at least as effective as federal standards.
Durable scaffolding wood Rough scaffolding wood treated with Woodcon for a water-repellent surface. Woodcon settles around the fibers of the wood and makes the scaffolding wood of your planter completely waterproof, all thanks to an transparent coating in-and-on the wood surface.
A grade that is suitable for support at centres up to 1.2m. It may be selected by visual or, preferably, machine strength grading. Each board is passed through a machine that measures deflection under a prescribed load. The board is tested in the plane that it will be used.
All planking or platforms must be overlapped a minimum of twelve (12) inches and secured from movement. Scaffold planks shall extend over their end support at least six (6) inches but no more than twelve (12) inches.
Assuming you are referencing a scaffold plank – the maximum load is based on a graded 2×10 plank with a span of up to 10 feet. The allowable loading is based on the span and is given in pounds per square foot. A plank with a 10foot span between supports is allowed a load of 25 pounds per square foot.

What is mobile scaffolding? Mobile scaffolds are temporary support platforms, on casters or wheels, used for construction work.
Two-point and multi-point suspension scaffolds shall be tied or otherwise secured to prevent them from swaying, as determined to be necessary based on an evaluation by a competent person.
Because working at heights poses significant risks, both to those working on the scaffold and those below, we do not recommend that you attempt to erect a scaffold on your own, unless you are trained and competent in scaffold erection. … The safety of lives is too important to make scaffolding a DIY project.

The maximum safe working load of a scaffold board is 150 KG evenly spaced. The total weight of the user and tools must not exceed this. When moving to a new site, carry the equipment with care.
Inspect wooden planks and ensure there are no cracks or splits greater than 1 /4-inch, long end splits, several large loose knots, warps greater than 1 /4 inch, boards and ends with gouges, mold, separated laminate(s), and grain sloping greater than 1 in 12 inches from the long edge.
For example, federal OSHA allows overhangs up to 18 inches for plank longer than 10 feet, California allows 18 inches for any length plank and the US Army Corps of Engineers limits all plank overhang to 12 inches, regardless of plank length.
A 2×12 can hold approximately 180 pounds per foot or approximately 2,100 pounds in total.
(4)(xv) Crossbracing is acceptable in place of a midrail when the crossing point of two braces is between 20 inches (0.5 m) and 30 inches (0.8 m) above the work platform or as a toprail when the crossing point of two braces is between 38 inches (0.97 m) and 48 inches (1.3 m) above the work platform.
The maximum load capacity of the wood table is about 150 lbs. (68kg). The average amount of weight that we use to keep on a desk is only about 15 lbs. In general, a wood table is well enough to bear any load, because it is actually difficult to imagine 150 lbs.
The standard requires employers to protect each employee on a scaffold more than 10 feet (3.1 m) above a lower level from falling to that lower level.
Rated Load Capacity of ScaffoldIntended Load Should BeLight-Duty “standard”25 pounds per square foot (applied uniformly)
Section 1926.451(b)(7) states, “on scaffolds where platforms are overlapped to create a long platform, the overlap shall occur only over supports, and shall not be less than 12 inches (30 cm) unless the platforms are nailed together or otherwise restrained to prevent movement.” The standard does not specify whether …
The most common method of sawing coniferous softwood is block-sawing, followed by resawing. With block-sawing, the log is rotated to the best position and sawn through to make optimum use of the log’s dimensions. It is then laid down so the centrecut can be sawn into boards and planks.
Explanation: the wooden plank cannot sustain the huge amount of pressure you are applying on it and that is the reason it breaks.
is that plank is a long, broad and thick piece of timber, as opposed to a board which is less thick while board is a relatively long, wide and thin piece of sawn wood or similar material, usually intended for use in construction or board can be (basketball|informal) a rebound.
