What is the type of scaffold that are usually supported on outriggers at the roof?

Scaffolding eTool Supported scaffolds consist of one or more platforms supported by outrigger beams, brackets, poles, legs, uprights, posts, frames, or similar rigid support.

What type of scaffold is considered a suspended scaffold?

Suspended scaffolds are platforms suspended by ropes, or other non-rigid means, from an overhead structure. Because two-point scaffolds are the most common type of suspended scaffold, this eTool uses the Two-Point module to describe requirements that apply to all suspended scaffolds.

What scaffolds consist of one or more platforms supported by outrigger beams?

Supported scaffolds are comprised of one or more platforms supported by outrigger beams, brackets, poles, legs, uprights, posts, frames, or similar rigid supports. Suspension scaffolds are comprised of one or more platforms suspended by ropes or other non-rigid means from an overhead structure.

What is an outrigger used for?

Outriggers are long poles that are fitted on both sides of a boat and are designed to hold fishing line. They allow you to reel in and release your fishing line via a system of pulleys and clips. Outrigger poles are available in many different lengths ranging from 12 to 35 feet.

What are supported scaffolds?

Supported scaffolds, which consist of one or more platforms supported by rigid, load- bearing members, such as poles, legs, frames, outriggers, etc. Suspended scaffolds, which are one or more platforms suspended by ropes or other non-rigid, overhead support.

What is a suspended scaffold?

A suspended scaffold incorporates a suspended platform capable of being raised or lowered when in use. Other terms often used are ‘suspended cradle’ and ‘swing-stage’ scaffold. They are typically prefabricated modular units (see Figure 1) or permanently fabricated units although they can be assembled from scaffolding.

What is the most common type of suspended scaffold?

Two-point adjustable suspension scaffolds, also known as swing-stage scaffolds, are perhaps the most common type of suspended scaffold.

What are the requirements for suspension scaffolds?

Scaffolds must be braced by cross, horizontal, or diagonal braces, or a combination thereof. Scaffolds must be plumb, level, and squared. All brace connections must be secured. Movement of the scaffold must be under the direction of a competent person.

What does an interior hung suspension scaffold consists of?

An interior hung suspension scaffold consists of a platform suspended from the ceiling or roof structure by fixed-length supports.

Article first time published on

How many platforms are on a supported scaffold?

Supported scaffolds consist of one or more platforms supported by outrigger beams, brackets, poles, legs, uprights, posts, frames, or similar rigid support. Guardrails or personal fall arrest systems for fall prevention/protection are required for workers on platforms 10 feet or higher.

What are the different types of scaffolds used in construction industry?

• Single Scaffolding.
• Double Scaffolding.
• Cantilever Scaffolding.
• Suspended Scaffolding.
• Trestle Scaffolding.
• Steel Scaffolding.
• Patented Scaffolding.

What is the required safety factor for suspension lines used with suspended scaffolds?

For temporary suspended scaffolds used in construction and general industry, the safety factor must be at least 6; that is, the suspension line must be 6 times stronger than the load you are placing on it.

What is outrigger structure?

Outriggers are typically horizontal structures (usually trusses or reinforced concrete walls) inserted into buildings at various levels to tie the concrete core to the outer (or perimeter) structural framework.

What is core and outrigger structural system?

The outrigger structural system is a lateral load resisting system in which the external peripheral columns are tied to the central core with very stiff outriggers and belt truss at or more levels. … The outrigger acts as a stiff arm engaging outer columns and central core.

What is a two-point suspension scaffold?

Two-point adjustable suspension scaffolds, also known as swing-stage scaffolds, are perhaps the most common type of suspended scaffold. Hung by ropes or cables connected to stirrups at each end of the platform, they are typically used by window washers, but play a prominent role in high-rise construction as well.

What is the difference between suspended and hanging scaffold?

A hanging scaffold is constructed with rigid tubes while a suspended scaffold hangs from ropes. … Outrigger Scaffolds are a type of supported scaffold.

What types of scaffolds are not allowed in construction?

(j) Prohibited Types of Scaffolds. Lean-to or jack scaffolds, shore scaffolds, nailed brackets, loose tile, loose brick, loose blocks, stilts, or other similar unstable objects shall not be used as working platforms, or for the support of such platforms.

What are some examples of scaffolding?

• Present the problem and think out loud. …
• Repeat as necessary. …
• Encourage participation. …
• Check understanding again. …
• Ensure students can demonstrate knowledge.

Why are scaffolding used?

Scaffolding is a temporary platform that is used for providing support on height and provides materials during a construction process for constructing or repairing of a structure. … Besides, it provides a certain level of support to a standing structure throughout the phase of construction.

What are 5 requirements for scaffolding?

• Robb Tinney, Safety Advisor. Safety Management Group.
• Start with training.
• Follow the instructions.
• Consider the hazards.
• Use a tagging system.
• Inspect and re-inspect.
• One more: respect their complexity.

Which of the following is allowed for accessing a scaffold?

Scaffold platforms that are more than two feet above or below a point of access must be accessed using ladders; ramps; walkways; integral prefabricated scaffold access; or direct access from another scaffold, structure, personnel hoist, or similar surface. Workers can’t use scaffold crossbraces to access a platform.

Who is responsible for training employees who perform work while on a scaffold?

OSHA 29 CFR 1926.454 says that: “The employer shall have each employee who performs work on a scaffold trained by a person qualified in the subject matter to recognize the hazards associated with the type of scaffolding being used and to understand the procedures to control or minimize these hazards.”

What is slung scaffold?

Slung scaffold This type of scaffold is suspended from the main structure in one position using wire ropes or steel chains. It is similar to birdcage scaffold but has the advantage of leaving a clear space beneath the platform.

What is stage scaffolding called?

Scaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other man-made structures.
