How much should a scaffold support?
OSHA requires that a scaffold be able to support its own weight and four times the maximum intended load.
Ropes for suspended scaffolds must support six times the maximum intended load.
If you are using a manufactured scaffold, the load you may place on it will be identified..
What is the maximum load for a scaffold?
875 poundsThe type of scaffolding being used is rated as light-duty, or 25 pounds per square foot. Multiply 35 square feet by 25 pounds per square foot and the scaffolding can be loaded with no more than 875 pounds.
What is the minimum size for scaffold planks?
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 closest you can generally build a scaffold near a power line?
It requires that a scaffold used in proximity to an insulated power line of less than 300 volts be no closer than 3 feet.
What are the 3 load ratings of scaffolds?
OHSA designates three different categories for load bearing calculations on scaffold boards. They are: Light Duty – 25 pounds per square foot. Medium Duty – 50 pounds per square foot. Heavy Duty – 75 pounds per square foot.

Can you tie off to scaffolding?
Question 3: Do the OSHA standards prohibit tying off to a scaffold? Answer: No. It is OSHA’s position that scaffolding can function as a suitable anchorage for fall arrest systems when the scaffolding section so used is erected and braced such that the criteria of §1926.502(d)(15) are met.
What is the minimum plank width for a ladder jack scaffold?
18 inches17.3. 2 The minimum width of the platform of a ladder jack scaffold shall be 18 inches when a wood plank is being used and 12 inches when a fabricated platform is being used.
How much weight can a scaffold tube hold?
The working tensile load that a steel scaffold tube will carry is around 79 kN (about 8 tonnes). This is based on the area of a 48.3 o/d tube 4.47mm wall thickness, no allowance for tolerance made from HE30TF alloy with a yield stress of 255 N/mm2.
How wide is scaffolding?
The scaffolding width is determined by the width of the boards, the minimum width allowed is 600 mm but a more typical four-board scaffold would be 870 mm wide from standard to standard. More heavy-duty scaffolding can require 5, 6 or even up to 8 boards width.
How do you calculate scaffolding?
Divide the total height measurement by the height of a single scaffolding section. This will determine the total number of rows of scaffolding the project will require. Multiply the number of rows by the number of columns to find the total number of scaffold sections necessary for the project.
Which scaffolding can hold more weight?
These types of scaffolds are best used when weight is spread out along the platform. A light-duty scaffold can hold about 25 pounds per square foot, a medium-duty scaffold can carry 50 pounds per square foot, and a heavy-duty one will hold 75 pounds per square foot.
What are the 3 types of scaffolds?
Workers who use scaffolds can be divided into three groups:Suspended Scaffolds.Supported Scaffolds.Aerial Lifts.
What is the longest scaffold tube?
Galvanised Scaffold tube is available in sizes, up to 21ft / 6.4m in length. Tube size: 48.3 x 4.0mm wall thickness.
What is the maximum gap between scaffold and structure?
300 millimetresThe gap between a working platform and the face of the structure must be as small as possible, except in the case where it is necessary for a person to sit on the edge of the platform to work, when the gap should not exceed 300 millimetres.
