The New Steel Erection Rule:

Highlights

2

Steel Erection Final Rule

• Published January 18, 2001

• Implemented January 18, 2002

• Includes exceptions for some provisions

3

Scope

• Covers all employers engaged in steel erection activities

• Contains two lists of activities:– Primary list: All are covered (connecting,

bracing, guying…)– Ancillary list: Covered only “when they occur

during and are a part of steel erection activities” (sealing, caulking, etc…)

1926.750(b)

4

Scope (cont’d)

• Does not apply to:– Electrical transmission towers

– Communication and broadcast towers

– Tanks

1926.750(a)

Steel Erection Decision Tree

Is the activity at the jobsite listed in 1926.750(b)(1)?

Yes No

IS the activity listed in .750(b)(2)?

Then this activity IScovered by Subpart R

Yes No

Then you must determine if this is going on in conjunction with (during and a part of) steel

erection activities in (b)(1). A question to ask: Does this (b)(2) activity have to be done for steel erection to continue: If yes, and if doneduring (b)(1) activities, then it is covered by

the standard.

Because it is listed in neither(b)(1) nor (b)(2), it is notcovered by the standard.

• Fall protection

• Worker training

8

Site Layout

• Adequate layout area

• Adequate access roads

9

Hoisting and Rigging

• Provides additional crane safety for steel erection

• Minimizes employee exposure to overhead loads through pre-planning and work practice requirements

1926.753

10

Hoisting and Rigging (cont’d)

• Prescribes proper procedures for multiple lifts (Christmas-treeing)

11

Column Anchorage

• Minimum 4 anchor bolts per column

• Written notification of proper curing of concrete in footings, piers, walls for steel columns

• Written notification of adequacy of anchor bolts modified/repaired in the field

1926.752(a)1926.755

12

Beams and Columns

• Two bolts per connection before releasing hoisting line

• Safe procedures for making double connections at columns

1926.756

13

Open Web Steel Joists

• Minimize the risk of collapse of lightweight steel joists by:– Specifying erection bridging

and method of attachment– Requiring erection bridging to

be anchored to terminus point– Specifying method of placing

loads on steel joists

1926.757

14

Structural Steel Assembly

• Specific work practices:– Hoisting deck bundles

1926.754

15

Structural Steel Assembly (cont’d)

• Minimizing fall hazards:– Trip hazards– Interior holes/openings– Slip hazards

1926.754

Shear Connectors

16

Systems-Engineered Metal Buildings

• Requirements to minimize the risk of collapse in the erection of these specialized structures that account for a major portion of steel erection in this country

1926.758

17

Falling Object Protection

• Provisions that address hazards of falling objects in steel erection

1926.759

Note: Does not apply to materials being hoisted

18

Fall Protection

• Above 30 feet/2 stories: All workers must be protected, including connectors and deckers

• Between 15 and 30 feet/2 stories: Workers must be protected EXCEPT:– Connectors– Deckers working in controlled decking

zone (CDZ)

1926.760

19

Fall Protection (cont’d)

• Connectors between 15 and 30 feet/2 stories– All equipment necessary

to be capable of being used to be tied off (or safety nets) must be in place

– Not required to tie off

1926.760(b)

20

Fall Protection (cont’d)

• Deckers between 15 and 30 feet/2 stories– Can use a controlled

decking zone (CDZ) instead of fall protection

1926.760(c)

21

Training

• Qualified person to train exposed workers in fall protection

• Qualified person to train exposed workers engaged in special, high- risk activities

1926.761

22

Specific Controlling Contractor Duties

• Notify the steel erector in writing regarding concrete cure and anchor bolt changes

• Provide adequate layout areas and onsite access roads

• Preclude work below steel erection unless there is overhead protection

• Choose whether to accept responsibility for maintaining fall protection equipment left by erector (otherwise it must be removed)
