Scaffolding Generally Speaking

• Means any temporary elevated platform (supported
  or suspended) and its supporting structure
  (including points of anchorage), used for
  supporting employees or materials or both.

4
Always, Always, Always!

• Inspect scaffolding and components prior to each
  work shift
• Determine feasibility of providing fall
  protection and access
• Evaluate connections to support load and prevent
  swaying
• Determine structural soundness when intermixing
  components manufacturer
• Train erectors and dismantlers to recognize work
  hazards

Scaffolding Construction 1926.451(b)

• - Max openings between platform and uprights 9
  -1/2
• - Platform and walkways at least 18 wide
• - Each abutted end shall rest on a separate
  support surface
• - Overlap platforms not be less than 12 only
  over supports unless restrained to prevent
  movement

Scaffolding Construction contd.

• Front edge of all platforms
• No more than 14 from face of work
• 3 from face for outrigger scaffolds
• 18 from face for plastering and lathing
  operations
• Platforms 10 and less to extend at least 6 but
  not more than 12 past support
• Platforms greater than 10 nor more than 18 past
  support unless

1926.451(c) Supported scaffolds

• Must bear on adequate foundations
• Unstable objects will not be used as working
  platforms
• Plumbed and braced
• Scaffold platforms must be fully planked

• Never overloaded
• Erected, moved, dismantled and altered near power
  lines
• Repair in place or replace damaged components
• Restrict horizontal movement with employees

What OSHA Says1926.452(f)

• Scaffolds shall not be constructed or arranged
  more than two tiers or 10ft.
• When arranged in tiers, each horse shall be
  placed directly over the horse in the tier below
• When arranged in tiers, the legs of each horse
  shall be nailed down or otherwise secured
• Each tier shall be crossbraced

14
Statistics

• 25 of workers injured in scaffold accidents had
  received no scaffold safety training
• OSHA estimates that informed employers and
  workers, in compliance with correct safety
  standards, can save as many as 50 lives and
  prevent 4,500 accidents every year.

DANGER!!!!
16
Common Hazards Associated with Scaffolding

• Falls from elevation, due to lack of fall
  protection
• Collapse of the scaffold, caused by instability
  or overloading
• Being struck by falling tools, work materials, or
  debris and
• Electrocution, principally due to proximity of
  the scaffold to overhead power lines.
