At what height is scaffolding required?
Scaffolding is required for jobs where the height is greater than 4 feet above a lower level. For construction jobs the requirement is 6 feet above a lower level. Although the type of scaffolding used may vary, it should always be erected properly and maintained throughout the project to ensure worker safety.
What is the safe height for scaffolding?
"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)."

How many levels of scaffolding are there?
Frame scaffolding, also known as fabricated scaffolding, is the most common type of supported scaffolding because it is economical, easy to set up and tear down, and the most versatile. In this scaffolding type, modular pieces are used to build the scaffolding from the ground up.
What is a Class 4 scaffold?
Effective classrooms have been shown to have two broad levels of scaffolding operating: macro-level and micro-level scaffolding (Hammond 2001). Macro-level scaffolding operates at the level of a program or unit of teaching and learning.

Protection for Those Below
If items on the scaffold are taller than the toe board, other systems, like debris nets, must be used to catch falling tools or materials. Always wear a hard hat when working on and around a scaffold. Never walk under or near the scaffold if roped off when work is being performed above.

Planks slipping or breaking
If scaffold planks are unsecured, overloaded or in bad condition, they can break or slide which causes many falls and injuries.
Which scaffold is prohibited?
This is because scaffolding systems often rely on anchoring into existing facade elements for lateral stability. The scaffold design may also require leg supports to rest on top of existing roofs or walls that will impart gravity loads into delicate structural elements.
Can you walk under scaffolding?
Scaffolders typically work during all types of weather conditions, including rain. The nature of the job means that they are often exposed to the elements, and as such need to be prepared for any eventuality. Rain does not necessarily prevent them from working, but it can make their job more difficult and dangerous.

Scaffolding not only allows workers to reach taller heights, it also provides a better position to work on walls, ceilings, outdoor spaces and windows. Scaffolding offers a sturdy, solid structure, so there are less risks than there would be with a ladder for example.
What are the unsafe conditions of scaffolding?
Scaffolding can be crucial for construction, since it allows workers to stand at height on a stable surface. This is especially true for skyscrapers and other high rise structures, but its use is also common for construction work done closer to the ground.

Benefits of Scaffolding in Education
Improves the likelihood that students will retain new information. Helps connect foundational knowledge to new concepts. Engages students with their learning and tracking their own progress. Gives students more autonomy and independence in the classroom.
