  1. Walking-Working Surfaces

  2. Housekeeping is more than being tidy • All areas are clean, orderly, and sanitary • Floors are clean and dry • Areas free of protruding nails, splinters, holes, or loose boards 1a

  3. Permanent aisles • Kept clear • In good repair • No obstructions • Appropriately marked • Sufficiently wide 2a

  4. Open pits, tanks, vats, ditches, etc • Protect with: • Covers • Guardrails 3a

  5. Floor loading limits • Marked on plates • Conspicuously posted 4a

  6. Floor and wall openings and holes are guarded when • Four feet or more above adjacent levels 5a

  7. Ladders and stairs • Injuries occur when ladders: • Move • Slip • Fall • Break 6a

  8. Ladders and stairs • Injuries occur when: • Employees carry things in their hands when they fall 6b

  9. Ladders and stairs • OSHA sets requirements for design, construction, and use of: • Portable wood ladders • Portable metal ladders • Fixed ladders • Stairs 6c

  10. Ladders and stairs • Tips for ladders: • Inspect before use • No metal ladders near electrical lines • Use for intended purpose 6d

  11. Ladders and stairs • Tips for ladders: • Set up on firm, solid surface • Lock spreaders on stepladders • Use 4 to 1 rule to set up straight ladders 6e

  12. Ladders and stairs • Tips for ladders: • Use both hands • Stay off top steps • Don't move occupied ladders • Hoist items up to you • Work within side rails 6f

  13. Ladders and stairs • Tips for stairs: • No slippery, wet, or icy conditions • Free of clutter • Use handrails • See your path 6g

  14. Scaffolding • Scaffold injuries occur while: • Working on the scaffold • Climbing between levels 7a

  15. Scaffold terms • Bearer • Brace • Coupler • Crawling board • Double pole • Guardrail 8a

  16. Scaffold terms • Heavy duty scaffold • Horse scaffold • Ladder jack scaffold • Ledger • Light duty scaffold 8b

  17. Scaffold terms • Maximum intended load • Medium duty scaffold • Mid-rail • Putlog • Runner 8c

  18. Scaffold terms • Toeboard • Tube and coupler scaffold • Tubular welded frame scaffold • Two-point suspension scaffold • Working load 8d

  19. Scaffold design, construction • Sound footing • Safely support maximum intended loads 9a

  20. Scaffold design, construction • Poles, uprights are plumb, rigidly braced • Secured to permanent structures 9b

  21. Scaffold design, construction • Proper grades of timbers and planking • Nails, bolts 9c

  22. Scaffold design, construction • Spans for planks • Planks overlapped, secure • Planks extend over end supports 9d

  23. Scaffold design, construction • Safe access • Damaged are out of service, repaired 9e

  24. Scaffold safe work practices • Don't move or alter while occupied • No work during storms, high winds • Remove ice, snow and apply sand 10a

  25. Scaffold safe work practices • Hoisted items need tag lines • Protection during hot work • Screen to guard workers below 10b

  26. Mobile ladder stands, scaffolds • Designed and built: • Strong enough to support weight • Using sturdy materials 11a

  27. Mobile ladder stands, scaffolds • Work platforms: • Rigidly braced • Wide enough • Guardrails, toeboards above 10 feet • Maximum height 11b

  28. Other working surfaces • Dockboards • Forging machine area • Veneer machinery 12a

  29. Other working surfaces • Dockboards: • Built to industry standards • Secured in position • Handholds provided • Prevent rail car movement 12b
