  1. OSHA’S NEW STEEL ERECTION STANDARD When industry and labor work together, we can save lives.

  2. Steel Erection Activities • Every year, an average of 35 iron workers die during steel erection activities and 2,300 more suffer lost workday injuries,"

  3. Standard • New subpart R is the first OSHA safety standard developed under the Negotiated Rulemaking Act • Developed by members of the Steel Erection Negotiated Rulemaking Advisory Committee (Senrac)

  4. The Final Rule Contains Requirements For: • Hoisting and rigging • Structural Steel Assembly • Beam and Column connections • Joist Erection • Systems-engineered Metal Building Erection • Fall Protection • Training

  5. The new standard covers all workers engaged in steel erection activities • The Standard does not cover electric transmission towers, communication towers, broadcast towers, water towers or tanks

  6. Effective Dates • Original effective date July 18, 2001 • Revised effective date Jan. 18, 2002.

  7. Additional Time • Gives industry time to become familiar with the new requirements and to provide training to employees in the construction industry. • Allow employers time to make the necessary changes to avoid costly re-fabrication of already made components and avoid serious delays to projects that would affect all trades involved in the construction process.

  8. Question • Is the construction of a house framed with metal studs within subpart R? • No. A housed framed with metal studs is not covered by the standard

  9. Question • When would the installation of metal studs be covered by subpart R? • The installation of metal studs is covered by Subpart R when the studs are integrated with the structural steel framing of a building.

  10. Question • Is the installation of a standing seam metal roof on a wood framed structure covered by subpart R? • Yes. The definition of metal decking includes standing seam metal roofs.

  11. Question • A fabricated tank is installed on a pad. The tank has connection points for a catwalk pre-installed by the manufacturer. The catwalk will be installed by a crane crew after the tank is installed. Do the fall protection requirements of subpart R apply to the installation of the catwalk?

  12. Answer • Yes. Catwalks has traditionally been considered miscellaneous metals, and the installation of miscellaneous metals is covered by Subpart R?

  13. Major causes of injuries and fatalities in the steel erection industry • Working under loads • Hoisting, landing and placing decking • Column stability • Double connections • Landing and placing steel joints • Falls to lower levels.

  14. 1926.751: Definitions

  15. Competent Person • Means one who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.

  16. Controlling Contractor • Means a prime contractor, general contractor, construction manager or any other legal entity which has the overall responsibility for the construction of the project -- its planning, quality and completion.

  17. Qualified person • One who, by possession of a recognized degree, certificate, or professional standing, or who by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter, the work, or the project.

  18. Shear Connector • Headed steel studs, steel bars, steel lugs, and similar devices which are attached to a structural member for the purpose of achieving composite action with concrete.

  19. Site-Specific Erection Plan • Requires pre-planning of key erection elements, including coordination with controlling contractor before erection begins, in certain circumstances.

  20. Steel Erection • Construction, alteration or repair of steel buildings, bridges and other structures, including the installation of metal decking and all planking used during the process of erection.

  21. 1926.752: Site Layout & Construction Sequence

  22. Controlling Contractor • Steel Erector provided notification of: • Concrete having attained sufficient strength. • Alteration of anchor bolts. • Adequate access to storage areas. • That concrete has cured enough to support steel erection

  23. Hoisting operations • Must be pre-planned to reduce employee exposure to overhead loads.

  24. Question • Can the controlling contractor contract with subcontractor to perform the work required by 1926.752(a)? If so, is the controlling contractor still responsible for these duties after subcontracting them? • Yes. The Controlling contractor is responsible for ensuring that the work was performed.

  25. Question • Does the written notification from the controlling contractor to the steel erector about concrete footing, etc. in 1926.752(a) & (b) have to be maintained on site? • Once the written notification is given to the erector, there is no requirement that it be maintained at the site.

  26. Question • Does the anchor bolt repair, replacement or field -modification approval from the Structural Engineer of Record (SER) required by 1926.755(b)(1) have to be maintained on site? • No. Once the written notification is given, it does not have to be maintained on site.

  27. 1926.753: Hoisting & Rigging

  28. 1926.753 - Hoisting and rigging(Supplement to the requirements of 1926.550) Construction Safety Council

  29. Pre-shift Inspection Requirements • Pre-shift inspection must be done by a competent person. • Rigging must be inspected prior to each shift by a qualified rigger

  30. Pre-shift visual inspection of cranes: • all control mechanisms for maladjustments excessive wear of components and contamination by lubricants or other foreign matter • safety devices • hooks and latches • pressurized lines for leakage • wire rope • electrical apparatus • hydraulic system • tires • ground conditions • hoisting equipment Construction Safety Council

  31. General • The employer shall obtain and/or prepare a certification record of the pre-shift inspection Construction Safety Council

  32. General • The operator shall be responsible for those operations under the operator’s direct control Construction Safety Council

  33. General • Qualified rigger to inspect the rigging prior to each shift • Headache ball not used to transport personnel • Only use of personnel platforms in accordance with 1926.550 (g) Construction Safety Council

  34. Safety Latches • Safety latches on hooks shall not be deactivated. Construction Safety Council

  35. Responsibilities During Crane Operations • Safety latches • Employees engaged in initial steel erection or hooking/unhooking to work under loads in some specific instances. • Operators are responsible for operations under their control and have the authority to stop and refuse to handle loads until safety has been assured.

  36. Responsibilities During Crane Operations • Prohibit the use of cranes to hoist personnel unless ALL provisions of 1926.550 are met except 1926.550(g)(2) • When working under loads requirements in this section must be followed. • Multiple lift rigging is permitted as long as the requirements in this erection are met. [.753(d)].
