•OSHA studies of 673 fatalities among ironworkers highlighted common hazards

•Deaths were largely preventable by engineering & regulatory changes

•Controlling contractor must provide written notification that concrete has attained

– 75% of design strength, or– Sufficient strength to

support the loads

•Controlling contractor must ensure that adequate access roads are provided and maintained

8


Controlling contractor must ensure that a suitable space is provided for

–storage of materials and–safe operation of hoisting operations

9


All hoisting operations must be preplanned to ensure all “working under loads” requirements are met

10


•A site-specific erection plan may be developed to provide alternate means to protect employees

•Appendix A contains guidelines

Example

“Steel erection must be done under the supervision of a competent person who is present at the worksite.”

Hoisting & RiggingHoisting & Rigging When working under loadsWhen 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

21

Hoisting & RiggingHoisting & Rigging Multiple lift rigging procedureMultiple 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


22


– Bundles of decking are NOT appropriate for multiple lift.

– Even though metal decking meets the definition of structural members

23


•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

24


Total load must not exceed•rated capacity as specified in the hoisting equipment load charts and

•rigging capacity specified in the rigging-rating charts

25


Controlled load lowering must be used whenever the load is over the connectors

Decking gaps around columns

where there are gaps between columns, the “falling objects hazards” must be eliminated

During installation, metal decking must be laid tightly & immediately secured to prevent movement

38


During installation, metal decking panels must be placed to ensure full support by structural members

39


Derrick floors must be fully decked or planked & connections completed

40


Temporary loads placed on derrick floors must be distributed over the underlying support to prevent local overloading
