When industry and labor work together, we can save lives. OSHAS NEW STEEL ERECTION STANDARD
Steel Erection Activities Every year, an average of 35 iron workers die during steel erection activities and 2,300 more suffer lost workday injuries,"
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)
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
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
Effective Dates Original effective date July 18, 2001 Revised effective date Jan. 18, 2002.
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.
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
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.
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.
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?
Answer Yes. Catwalks has traditionally been considered miscellaneous metals, and the installation of miscellaneous metals is covered by Subpart R?
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.
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.
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.
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.
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.
Site-Specific Erection Plan Requires pre-planning of key erection elements, including coordination with controlling contractor before erection begins, in certain circumstances.
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.
: Site Layout & Construction Sequence
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
Hoisting operations Must be pre-planned to reduce employee exposure to overhead loads.
Question Can the controlling contractor contract with subcontractor to perform the work required by (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.
Question Does the written notification from the controlling contractor to the steel erector about concrete footing, etc. in (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.
Question Does the anchor bolt repair, replacement or field -modification approval from the Structural Engineer of Record (SER) required by (b)(1) have to be maintained on site? No. Once the written notification is given, it does not have to be maintained on site.
