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

6 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

8 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 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 10 Site layout, site-specific erection plan & construction sequence A site-specific erection plan may be developed to provide alternate means to protect employees Appendix A contains guidelines Example App A

11 11 An Example of Alternate Means To Protect Employees (e) Safety latches on hooks must not be deactivated or made inoperable except: (i) When a qualified rigger has determined that the hoisting and placing of purlins and single joists can be performed more safely by doing so; or (ii) When equivalent protection is provided in a site-specific erection plan.

12 12 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. competent person TOC Next Section

13 13 : Competent Person Definition: Competent Person One who can identify existing or predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has the authorization or authority by nature of their position to take prompt corrective measures to eliminate them.

14 14 Hoisting & Rigging The new section (WAC ) and WAC & -526WAC & -526 Both apply to hoisting and rigging Photo courtesy of National Ironworkers & Employers Apprenticeship Training and Journeyman Upgrading Fund. All rights reserved.

15 15 Hoisting & Rigging Crane preshift visual inspection must be visually inspected by a competent person rule gives inspection minimumsinspection 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.

16 16 Inspection Minimums: All control mechanisms for maladjustments; Control and drive mechanism for excessive wear of components and contamination by lubricants, water or other foreign matter; Safety devices, including boom angle indicators, boom stops, boom kick out devices, anti-two block devices, and load movement indicators where required; Air, hydraulic, and other pressurized lines for deterioration or leakage, particularly those which flex in normal operation; Hooks and latches for deformation, chemical damage, cracks, or wear; Wire rope reeving for compliance with hoisting equipment manufacturer's specifications; Electrical apparatus for malfunctioning, signs of excessive deterioration, dirt, or moisture accumulation; Hydraulic system for proper fluid level; Tires for proper inflation and condition; Ground conditions around the hoisting equipment for proper support, including ground settling under and around outriggers, ground water accumulation, or similar conditions; The hoisting equipment for level position; and The hoisting equipment for level position after each move and setup.

Metal decking at roof and floor holes and openings must be installed as follows: (i) Framed metal deck openings must have structural members turned down to allow continuous deck installation except where not allowed by structural design constraints or constructibility. (ii) Roof and floor holes and openings must be decked over.
