What Is A Scaffold?

A scaffold is an elevated, transient work platform.

 Three fundamental types:

Supported scaffolds — systems supported through rigid, load-bearing members, including poles, legs, frames, & outriggers.

Suspended scaffolds — systems suspended through ropes or different non-rigid, overhead help.

Aerial Lifts — including “cherry pickers” or “growth trucks”.

Hazards of scaffold

Employees operating on scaffolds are uncovered to those hazards:

  • Falls from elevation – due to slipping, dangerous access, and the dearth of fall safety
  • Struck through falling tools/particles
  • Electrocution – from overhead strength lines
  • Scaffold collapse – due to instability or overloading
  • Bad planking giving way.

(About 2 of each 3 production people (2. three million) paintings on scaffolds frequently. Protecting those people from scaffold-associated injuries could save you 4,500 accidents and 50 deaths each year, at a financial savings of ninety million in workdays now no longer lost.)

Fall Hazards Falls can also additionally occur:

  • While mountaineering on or off the scaffold
  • Working on unguarded scaffold systems
  • When scaffold systems or planks fail Protecting Workers from Falls If an employee on a scaffold can fall extra than 10 feet, guard them through:

Guardrails, and/or • Personal Fall Arrest Systems (PFAS) (Reference 1926.451(g)

Personal fall arrest system” (PFAS)

  • A machine is used to arrest a worker’s fall. It includes an anchorage, connectors, a frame belt, or frame harness and can encompass a lanyard, deceleration device, lifeline, or combos of those.
  • The form of fall safety required relies upon the sort of scaffold being used.


  • Install alongside open aspects & ends
  • Front fringe of systems now no longer extra than 14 inches from the paintings, until the use of guardrails and/or PFAS
  • Top rails – 38 to forty-five inches tall
  • Midrails midway among top rail and platform
  • Toeboards at the least three-half of inches high

Reference 1926.451(g)(1), (g)(4), (b)(three), and Appendix A, paragraph 1d.

  • 38-inch minimal guardrail top in which guardrail is number one fall safety.
  • 36-inch minimal guardrail top in which fall arrest structures are number one fall safety.
  • Protect from falling among the pinnacle rail and floor, through the use of mid-rails, displays, or mesh.
  • Protective obstacles need to be sturdy sufficient to help a falling worker. Wood, chain, and twine rope will be used for pinnacle rails and mid rails.
  • Top rails – 36-forty eight inches tall while the use of the move bracing because the pinnacle rail When move bracing is used as a mid-rail, it needs to be among 20 and 30 inches above the painting’s platform.

Guardrails aren’t required:

  • When the front give up of all systems is much less than 14 inches from the face of the paintings
  • When outrigger scaffolds are 3 inches or much less from the front edge
  • When personnel is plastering and lathing 18 inches or much less from the front edge. Personal Fall Arrest Systems (PFAS) You need to gain knowledge of a way to nicely use PFAS PFAS encompass anchorage, lifeline, and frame harness.

Reference 1926.502(d) and 1926.503

Personal Fall Arrest Systems=frame belts, harnesses, and their components, including anchorage points, lifelines, dee rings, and snap hooks.

What will my non-public fall arrest machine do to guard me?

A non-public fall arrest machine locations the worker right into a frame harness this is mounted to a stable anchorage in order that he/she can’t fall. Body belts aren’t applicable as non-public fall arrest structures. A few key requirements:

  • There needs to be no loose fall extra than 6 feet.
  • There needs to be a spark off rescue after a fall.
  • Inspect PFAS’s previous to every use.
  • Don’t use PFAS’s till they’ve been inspected through a ready individual.

A ready individual needs to decide the feasibility and protection of offering fall safety for personnel erecting or dismantling supported scaffolds.

Fall Protection Requirements

  • l Can use PFAS as opposed to guardrails on a few scaffolds l
  • Use PFAS & guardrails on suspension  l
  • Use PFAS on erectors and dismantlers in which is feasible.

Reference 1926.451(g).

What fall safety will I want while operating on scaffolds?

  • Boatswains’ chair, catenary scaffold, waft, needle beam, and ladder jack scaffold non-public fall arrest machine.
  • Single-factor or two-factor adjustable non-public fall arrest machine and a guardrail machine.
  • Crawling board (hen ladder) – non-public fall arrest machine, a guardrail machine, or through a 3-fourth inch diameter grab line or equal handhold securely mounted beside every crawling board.
  • On a walkway inside a scaffold – guardrail machine set up inside nine ½ inches of and alongside at least one aspect of the walkway § On a supported while acting overhand bricklaying operations – non-public fall arrest machine or guardrail machine on all open aspects and ends of the.
  • For all different, a non-public fall arrest machine or a guardrail machine.

Falling Object Protection

  • Wear hardhats.
  • Barricade place under scaffold to forbid access into that place.
  • Use panels or displays if the cloth is stacked better than the toe board.
  • l Build a cover or erect an internet under the scaffoldss to be able to include or deflect falling items.

Reference 1926.451(h)(1) & (2) & (three).

l How am I covered from falling items

after I am operating on a scaffold? l The primary safety is to usually put on a hardhat. In addition, while there may be the hazard of falling hand tools, particles, and different small items, the organization need to despoliation toe boards, displays, or guardrail structures above the employee on a , or via the erection of particles nets, trap systems, or cover systems that include or deflect the falling items. l When the capability falling items are too massive to be held through toe boards, displays, or guardrail structures, the organization need to vicinity such items far from the brink of the floor from which they might fall and need to stable the one’s substances as important to save you their falling.

l Workers on scaffolds need to be aware of personnel operating under them, who’re at hazard from items falling from the . Where this hazard exists, the organization needs to erect a barricade to hold personnel from operating under the  or need to vicinity a toeboard or an edging alongside the brink of the platform.
