LADDER

ANTI SKIDS

Safe Procedure of LADDER ‘3 point contact’ -2 hands, 1 foot or

2 feet 1 hand when ascending or descending.

Ratio(1:4), safe angle-75˚(for supported) safe angle-45˚(for un-supported)

Safe Procedure of LADDER Distance b/w 2 rugs(25-35cm) Anti skids at bottom Last rung to be painted for wodden

ladder(rung thickness -28mm) Iron ladder should painted to

identify welding cracks(rung thickness-19mm)

SCAFFOLD MOVABLE PERMANENT HANGING WALL BASED

What Is A Scaffold?An elevated, temporary work platform

Two basic types: Supported scaffolds -- platforms

supported by rigid, load bearing members, such as poles, legs, frames, & outriggers

Suspended scaffolds -- platforms suspended by ropes or other non-rigid, overhead support

Scaffold? Scaffold means an temperorly

provided structure on or from which building workers perform work in connection with building or other construction work.

MODULAR SCAFFOLD

MOBILE SCAFFOLD

16

Install along open sides & ends

Front edge of platforms not more than 14 inches from the work, unless using guardrails and/or PFAS

Top rails - 38 to 45 inches tall

Mid rails halfway between top rail and platform

Toe boards at least 3-1/2 inches high

Guardrails

Work Safe Program

RAILING

Scaffold Support Examples

Good support Inadequate support – in danger of collapse?

Base plate

Mud sills

LOAD&HEIGHT OF SCAFFOLD Load is inversely proportional to the bay length Max height of scaffold is 4 timmes width of the scaffold Every 9 mt provide a landing
