  3. Navigational Symbols Used in this Presentation • Return to the program, usually from “additional information” • Definitions, more information, FAQs, etc • Read the actual Standard on line • Back to the Outline Next slide

  4. Why the new rules?? • OSHA studies of 673 fatalities among ironworkers highlighted common hazards • Deaths were largely preventable by engineering & regulatory changes

  5. = Outline -703 -Site layout, site specific erection plan & construction sequence -704 - Hoisting & rigging -706 - Structural steel assembly details -707 - Column anchorage -708 - Beams & columns -709 - Open web steel joists -711 - Systems engineered metal buildings -714 - Falling object protection -716 - Fall protection -717 - Training

  6. Site layout, site-specific erection plan & construction sequence • Controlling contractor must provide written notification that concrete has attained • 75% of design strength, or • Sufficient strength to support the loads

  7. Site layout, site-specific erection plan & construction sequence • Controlling contractor must ensure that adequate access roads are provided and maintained Photo courtesy of National Ironworkers & Employers Apprenticeship Training and Journeyman Upgrading Fund. All rights reserved.

  8. Site layout, site-specific erection plan & construction sequence Controlling contractor must ensure that a suitable space is provided for • storage of materials and • safe operation of hoisting operations

  9. Site layout, site-specific erection plan & construction sequence All hoisting operations must be preplanned to ensure all “working under loads” requirements are met

  10. Site layout, site-specific erection plan & construction sequence Example • A site-specific erection plan may be developed to provide alternate means to protect employees • Appendix A contains guidelines App A

  11. TOC Site layout, site-specific erection plan & construction sequence “Steel erection must be done under the supervision of a competent person who is present at the worksite.” Next Section

  12. Hoisting & Rigging • The new section (WAC 296-155-704) and • WAC 296-155-525 & -526 Both apply to hoisting and rigging Photo courtesy of National Ironworkers & Employers Apprenticeship Training and Journeyman Upgrading Fund. All rights reserved.

  13. Hoisting & Rigging Crane preshift visual inspection must be visually inspected by a competent person • rule gives inspection minimums • deficiencies must be evaluated immediately • equipment posing a hazard must be placed out of service • operator has authority to stop and refuse any loads until safety is assured Photo courtesy of National Ironworkers & Employers Apprenticeship Training and Journeyman Upgrading Fund. All rights reserved.

  14. Hoisting & Rigging • A qualified rigger must inspect the rigging prior to each shift Photo courtesy of National Ironworkers & Employers Apprenticeship Training and Journeyman Upgrading Fund. All rights reserved.

  15. Hoisting & RiggingWorking under loads Routes for suspended loads must be preplanned to avoid endangering workers

  16. Hoisting & RiggingWhen working under loads • materials must be rigged to prevent unintentional displacement • hooks must have self-closing safety latches or equivalent • all loads must be rigged by a qualified rigger

  17. Hoisting & RiggingMultiple lift rigging procedure only when: • a multiple lift rigging assembly is used • specifically within manufacturer’s specifications & limitations • maximum of 5 members hoisted per lift • only beams & similar structural members are lifted • only trained employees involved Photo courtesy of National Ironworkers & Employers Apprenticeship Training and Journeyman Upgrading Fund. All rights reserved.

  18. Hoisting & RiggingMultiple lift rigging procedure • Bundles of decking are NOT appropriate for multiple lift. • Even though metal decking meets the definition of structural members

  19. Hoisting & RiggingMultiple lift rigging procedure • Components of the multiple lift rigging assembly must be specifically designed and assembled with a maximum capacity for total assembly and for each individual attachment point. • Based on manufacturer’s specifications with a 5 to 1 safety factor on all components

  20. Hoisting & RiggingMultiple lift rigging procedure Total load must not exceed • rated capacity as specified in the hoisting equipment load charts and • rigging capacity specified in the rigging-rating charts

  21. Next Section TOC Hoisting & RiggingMultiple lift rigging procedure Controlled load lowering must be used whenever the load is over the connectors

  22. Structural Steel AssemblyStructural stability maintained at all times during the erection process Multistory structures have permanent floors installed as the erection of structural members progresses • Within 8 floors of the concrete, or Photo courtesy of National Ironworkers & Employers Apprenticeship Training and Journeyman Upgrading Fund. All rights reserved.

  23. Structural Steel AssemblyStructural stability maintained at all times during the erection process Multistory structures have permanent floors installed as the erection of structural members progresses • Within 8 floors of the concrete, or • no more than 4 floors (or 48’) of unfinished bolting or welding above secured floor

  24. Structural Steel AssemblyWalking/working surfaces Elimination of tripping hazards: • no shear connectors or other similar devices …until after walking/working surface has been installed.

  25. Structural Steel AssemblyPlumbing up When deemed necessary by a competent person: Plumbing up equipment must be installed in conjunction with the steel erection process to ensure stability of the structure.

  26. Structural Steel AssemblyPlumbing up • When necessary, plumbing up equipment must be in place and properly installed before the structure is loaded with construction material

  27. Structural Steel AssemblyPlumbing up • Plumbing up equipment must be removed only with the approval of a competent person

  28. Structural Steel AssemblyMetal decking Hoisting, landing & placing of metal decking bundles • provisions to prevent “displacement” of decking during handling/storage Photo courtesy of National Ironworkers & Employers Apprenticeship Training and Journeyman Upgrading Fund. All rights reserved.

  29. Structural Steel AssemblyMetal decking • Roof & floor holes and openings Must be installed as described: Para 706(4)(b) Photo courtesy of National Ironworkers & Employers Apprenticeship Training and Journeyman Upgrading Fund. All rights reserved.
