  2. Stupid Set-ups • The plank is supported by an extension ladder, a closed step ladder and a straight ladder. • The guardrails are not acceptable. • There is no stability

  3. 1926.450 Scope, Application • Covers all scaffolds used in workplaces. • Does not apply to crane or derrick suspended personnel platforms, which are covered by 1926.550(g). • Aerial lifts are covered 1926.453.

  4. Scaffold Requirements • Be on a firm foundation with base plates • Be plumb, square and adequately braced • Have a fully planked work deck • Have guardrails over 10 feet • Be tied in over 4 Vert./1 Horiz. high • Have an adequate means of access

  5. Scaffold Capacity • Must be able support its own weight and 4 times the maximum intended load. • Scaffolds must be designed by a qualified person. • They must and built and loaded within design.

  6. Competent Persons • All scaffolds must be erected, moved, dismantled or altered only under the supervision of a competent person

  7. Scaffold Foundations • Scaffolds must have base plates, even when setting on a concrete floor. • Also, the lack of a base plate could damage the scaffold leg.

  8. Scaffold Foundations • Scaffold legs must be set on base plates and adequate mudsills. • There is no base plate and the scrap plywood is not adequate. • The scaffold frame could penetrate the plywood.

  9. Never on Masonry! • Scaffolds should never be set on bricks, masonry blocks, etc. • These are not structural elements and could crush under the scaffold load.

  10. Good Foundations Frames Mason’s Adjustable Hydro-mobile

  11. Plumb & Level The Scaffold • It all starts in the first bay. • If it is set plumb and square, the rest will follow.

  12. Guardrails 1926.451 (g) • Guardrails are required at 10 feet. • Fall protection can be used in lieu of guardrails on some scaffolds. • Top rails must be 38” to 45” high • You must have a mid rail. • Use of cross bracing is allowed in lieu of top rail or mid rails in some cases but not both.

  13. Use of Braces for Guardrails • Brace can be used as a Top Rail.

  14. Full Guardrails Mobile Scaffolds Fully Planked Deck Proper Access All Frame Bracing Stack Pins Locked Level Surface Diagonal Brace Total Height Less than 4 times Base

  15. Training Requirements 1926.454 • Workers must be trained in • Nature of electrical, fall, and falling object hazards • Correct procedures for protection of above • Proper use of the scaffold • Load capacities of scaffolds • Requirements of OSHA’s Subpart L • Retraining as necessary to restore proficiency

  16. BAD! Pump Jack Scaffolds • Must have an 18” platform. • Must have guardrails or other fall protection GOOD!
