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.

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.What is the distance between scaffolding?
Few Vital Points In Scaffolding The distance between the uprights (standards) should not be more than 3 feet if you are using it for some light work like painting and 6 ft if you are using it for heavy masonry work. If you have installed single scaffolding, the putlogs should bear well on the wall opening.
What is the minimum standard width of scaffold plank?
All scaffold planks must be inspected and tested before use. Lumber or manufactured scaffold planks used for a work platform must consist of at least two planks placed side by side to provide a work surface with a nominal width of 50 cm (20 in.), or nominal width of 30 cm (12 in.)
What is the distance of scaffolding?
The horizontal distance between steel brackets is about 3 metres. Mild steel bars or similar materials are required to tie any structure to maintain the bamboo scaffold in its position on every floor. The distance of adjacent putlogs is about 3 to 4 metres.
How many inches must the planks extend past their support?
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.How far should planks extend past the bearer?
Make sure that planks laid on the brackets extend at least 15 cm (6 in) beyond the frames at either end. Place brackets so the level where the worker stands is no more than 1 m (40 in) below the level where the material is stored.
At what height must scaffolding be anchored?Scaffolding becomes more unstable as you build it taller. According to OSHA, the scaffolding must be tied off at specific intervals as you go vertically up the wall. For the purposes of this post, “tie off” includes (guys, ties and braces). 5′ wide, the initial tie off must be at 20′.
Article first time published onHow much can a scaffold plank deflect?
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.
What is the maximum permitted gap between the guard rails on a working platform?
guardrails fitted all the way around every platform at a minimum height of 950mm and with a maximum 470mm vertical gap between the guardrails and the platform.
What is the standard size of scaffolding?
Scaffolding Basics The most common frame size is 5 foot wide and 5 foot tall, but a variety of other sizes are available depending on your needs.
What is scaffolding bracing?
Scaffold Brace: A rigid connection that holds one scaffold member in a fixed position with respect to another member, or to a building or structure.
Can scaffolding be permanent?
Experts say employees need to understand that scaffolds are not permanent structures and care must be taken when working on all stages of scaffolding – from their construction to the work that takes place on them.
What is the maximum spacing of a medium duty horse scaffold?
Maximum intended load (medium duty): 50 lb/ft. (2)(**) __________ Footnote(**) Horses shall be spaced not more than 8 feet apart for light duty loads, and not more than 5 feet apart for medium duty loads.
What is the maximum leg spacing on a medium duty scaffold?
3.6. 2 Medium duty scaffolds will have a post spacing of 8 feet longitudinal and 6 feet transverse, load rated at 50 lb./ft. and not exceeding 125 feet in height.
What is the maximum leg spacing on a light duty scaffold?
A light-duty tube and coupler scaffold shall have all posts, bearers, runners, and bracing of nominal 2-inch O.D. steel tubing. The posts shall be spaced no more than 6 feet apart by 10 feet along the length of the scaffold.
How do you stack scaffolding planks?
Haul Scaffolding Safely Stack up the planks, braces and bases on the bottom between the wheel wells, and stack the frames on top. Avoid propping the scaffolding frames up on the side of the bed. It’s best to have everything as low as possible so parts don’t get blown or bounced out.
How far past a ledger must a scaffold plank extend if it is not cleated or otherwise restrained?
The minimum 150 millimetre (6 inch) distance reduces the likelihood of a plank slipping off its supporting ledger. Limiting the distance that a plank can extend beyond its supporting ledger to 300 millimetres (12 inches) discourages workers from using the extended area as part of their working platform.
How many planks are required at the working platform level on scaffold?
Scaffold planks Because they are no wider than 12”, you will generally need 6 per section per platform.
Does scaffolding need to be attached to the building?
In general, most scaffolds need to be tied to an existing permanent structure. There are exceptions where there is a necessity for a scaffold to be designed without any ties. Usually this involves adding buttress bays and may also include the need for counterweights.
What does a red flag on a scaffold mean?
RED Red “DANGER” tags should be used during erection or dismantling when the scaffold is left unattended. Be sure to replace all green tags or yellow tags in the event a scaffold has been deemed unfit for use.

How much weight can a plank hold?
Rated load capacityIntended loadMedium-duty50 pounds per square foot applied uniformly over the entire span area.Heavy-duty75 pounds per square foot applied uniformly over the entire span area.One-person250 pounds placed at the center of the span (total 250 pounds).
What is the maximum distance between a toe board and a hand rail on a scaffold?
The “Working at Height Regulations 2005” stipulates that any gap between guardrails shall not exceed 470mm. The actual gap between top and mid-guardrail on the SafeStand® system is 360mm and the gap between the mid-guardrail and toeboard measures 435mm.
What is the maximum vertical distance between landings?
Where a ladder or run of ladders rises a vertical distance of 9 metres or more above its base, there shall, where reasonably practicable, be provided at suitable intervals sufficient safe landing areas or rest platforms.
At what height is edge protection required?
As stated in OSH Regulations, if any personnel or contractors are at risk of falling 2 metres or more from a flat edge such as scaffolds, stairs, landings and etc, then you will need “edge protection” in place.
