SCAFFOLD:
“A temporary elevated platform and its
  supporting structure used for supporting
  workmen, materials, or both" in
  the construction or repair of buildings an
  d other large structures.
Types of scaffolds
   Categories
     Suspended
     Supported, tubular
     Rolling
   Tubular scaffolding are further
    divided in 3 groups:
        Pipe & coupler ( Clamp)
        H frame
        Cuplock
Tubular scaffolding
 Frequently used in construction work.
 TUBE & COUPLER SCAFFOLD: “A
  scaffold constructed of steel tubing that
  serves as
  standards, ledgers, transoms, braces, a
  nd ties and specially designed scaffold
  couplers that serve to connect the
  various members”.

                            Sole Plates
VARIOUS PARTS OF
SCAFFOLDS
   STANDARD: “Vertical scaffold tube that bears the weight of the Scaffold”.
   LEDGER: “A lengthwise horizontal scaffold tube that extends from standard
    to standard, that supports the transoms and that forms a tie between the
    standards”.
   TRANSOM: “A horizontal transverse scaffold member, that may support
    platform units, and which is supported by at least two ledgers or connected
    directly to at least two standards”.
   COUPLER: “A component or device used to fix scaffold tubes together”.
   PLANK: “An individual timber board or fabricated component that serves as
    a flooring member of a platform”.
   HANDRAIL: “A barrier consisting of pipes erected to prevent workers from
    falling off an elevated work area”.
   TOE BOARD: A barrier min 150 mm height to prevent slip/fall of material
    from platform.
   MID RAIL
   MUDSILL(SOLE PLATE): IT IS A WOODEN PLATE THAT IS USED TO
    DISTRIBUTE THE SCAFFOLDING LOAD OVER A SUITABLE GROUND
    AREA.
   BASE PLATE:
   DIAGONAL BRACING
   ACCESS LADDER
MUDSILL(SOLE PLATE)

 IT IS A WOODEN PLATE THAT IS USED
  TO DISTRIBUTE THE SCAFFOLDING
  LOAD OVER A SUITABLE GROUND
  AREA.
 THE SIZE OF MUDSILL IS DETERMINED
  BY THE LOAD CARRIED OVER A
  PARTICULAR GROUND AREA, AND BY
  THE NATURE OF THE SOIL
  SUPPORTING THESE SILLS.
BASE PLATE
 IT SPREADS CROSS-
  SECTIONAL AREA OF
  THE STANDARD TO
  LARGE AREA.
 IT PREVENTS SINKING
  OF STANDARDS.
 IT PREVENTS
  OVERTURNING OF
  SCAFFOLD.
 IT CARRIES THE
  WEIGHT OF
  SCAFFOLD.
Guardrail & Midrail
“These barriers used to prevent fall of any persons from
  platform.”
 General Requirements for guardrail & midrail:-
 NOMINAL DIA.- AT LEAST 1.5 INCHES.
 SPACING OF POSTS- NOT MORE THAN 8 FEET.
 MUST BE CAPABLE OF WITHSTANDING A LOAD OF
  200 POUNDS WHEN APPLIED FROM ANY
  DIRECTION & AT ANY POINT ON THE TOP RAIL.
 THE HEIGHT OF TOP RAILSHOULD BE 42 INCHES
  FROM THE TOP OF RAIL TO PLATFORM LEVEL.
 MIDRAIL TO BE PLACED HALF WAY.
TOEBOARD

 HEIGHT OF TOE BOARD SHOULD BE AT
  LEAST 4 INCHES.
 TO BE MOUNTED WITHIN ¼ INCHES OF
  THE WORKING PLATFORM.
 PURPOSE IS TO STOP SUDDEN TRAVEL
  OF A PERSON ON SCAFFOLD PLATFORM
  AFTER SLIPPING.
   MANY FATAL ACCIDENTS HAVE OCCURRED WHEN PERSONS HAVE
    FALLEN DOWN FROM A SCAFFOLD DURING THE PROCESS OF
    CLIMBING OR WHILE GETTING DOWN.
   MUST PROVIDE SAFE ACCESS TO SCAFFOLD & SCAFFOLD
    PLATFORM.
   THE BOTTOM STEP OR RUNG OF LADDER ( hook-on ladder , attachable
    ladder or stairway type ladder whichever the case may be ) MUST NOT
    BE MORE THAN 24 INCHES ABOVE OR BELOW THE SCAFFOLD
    SUPPORTING LEVEL.
   FOR SUPPORTED SCAFFOLDS OF MORE THAN 35 FEET HEIGHT
    , PROVIDE A REST PLATFORM AT 35 FEET HEIGHT.
   PROVIDE A REST PLATFORM EVERY 12 FEET IN CASE OF STAIRWAY
    TYPE ACCESS LADDER
   Rungs should be round type only.
ACCESS LADDER
5 MAJOR MISHAPS.
1.   Person falling while climbing up or
     coming down.
2.   Person falling from the working
     platform / deck.
3.   Objects falling from a scaffold on to
     someone below.
4.   Object falling from above on to a
     worker on the scaffold.
5.   Tilting of scaffold or collapse of
     scaffold.
