What is the maximum recommended 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..
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 formula of load?
You can estimate the total running load by adding up the running wattages of all items to be powered. If the name plate show only amps and voltage the wattage can estimated by multiplying volts times amps to calculate watts. Amps times Volts equals Watts. The watts total divided by 1000 is kW.
Is standard of scaffolding?
BIS IS 3696-1 : 1987(R2002) | SAFETY CODE OF SCAFFOLDS AND LADDERS – PART 1: SCAFFOLDS | SAI Global.
Why are scaffold boards banned?
The ‘A’ in Grade A scaffold boards are a potential ‘accident waiting to happen’ because they are an unknown grade, warns Christian Brash from John Brash & Co. By rights, Grade A timber boards should have been consigned to history back in 2009, when the latest version of the British Standard came out.
What is the standard width of 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.
What’s the average price for scaffolding?

How high can you build a free standing scaffold?
“Consensus recommend that an unsecured, free standing scaffold be considered safe only when the total height is equal to or less than four times its minimum or least base dimension (width).”
What are some safety precautions for scaffolding?
Here are some of the best ways to observe proper safety precautions on the job and minimize the risk of scaffolding injuries.Prepare properly. … Ensure adequate training. … Securing the scaffold. … Don’t forget guardrails. … Regular maintenance and inspection. … Use personal protective equipment (PPE)
How high can you build scaffolding?
Scaffold tower can be erected in all shapes and sizes. The standard dimensions are 5 foot and 7 foot long. Reaching 5 foot high all the way up to 30 feet tall.
How is SWL of scaffold calculated?
Multiply 35 square feet by 25 pounds per square foot and the scaffolding can be loaded with no more than 875 pounds. Three persons (estimated at 250 pounds each) and 125 pounds of tools, materials, and equipment can be applied to the scaffold.
How many Scaffolders die a year?
Roofing and Scaffolding – 69 Deaths Falling or injuries sustained while falling accounted for 29% of all workplace deaths last year — and scaffolding is one of the most dangerous careers in the country after 69 people died at work since 2010.
How far can a scaffold board span?
These boards have a nominal thickness of 38mm, are 225mm wide and are available in varying lengths up to 3.9m (13′). Grade ‘A’ boards have a maximum support span of 1.2m.
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.
How do you stabilize scaffolding?
Once the scaffolding is assembled and in place, double-check that it’s level and resting securely on all four base plates or casters. If it rocks, readjust one of the screws to stabilize the scaffolding. Use the built-in ladders to climb the scaffolding. Don’t climb on the cross braces.
Which scaffolding holds more weight?
Weight Capacity 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.
How much weight can a scaffold board take?
150 KGThe 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.
