A crane is holding a solid-web beam while ironworkers install the end connections. Before the hoisting line is released, what minimum OSHA connection condition must be met?
Correct Answer
B) At least two bolts per connection, drawn up wrench-tight or equivalent
OSHA 1926.756(a)(1) requires solid web structural members to be secured with at least two bolts per connection, of the same size and strength shown in the erection drawings, drawn up wrench-tight or equivalent before the hoisting line is released. Other choices are too little or require final work beyond the release minimum.
Why This Is the Correct Answer
OSHA 1926.756(a)(1) requires solid web structural members to be secured with at least two bolts per connection, of the same size and strength shown in the erection drawings, drawn up wrench-tight or equivalent before the hoisting line is released. Other choices are too little or require final work beyond the release minimum.
Why the Other Options Are Wrong
Option A: Base the solid web member release response on one started bolt at one end only
Choice A gives One started bolt at one end only. Its specific error: the action skips the timing, documentation, or field-control step needed for Solid web member release.
Option C: All final bolts fully tensioned and inspected, leaving solid web member release unverified
In metals work, All final bolts fully tensioned and inspected is the wrong selection for Solid web member release: it answers the Solid web member release prompt with the wrong practical move.
Option D: Base the solid web member release response on a tack weld at the top flange
The trap in D is A tack weld at the top flange only. That selection is wrong because the option delays or omits the controlling step.
Memory Technique
Make solid web member release a tabbed card: cite the exact condition, then choose At least two bolts per connection, drawn up wrench-tight or equivalent.
Reference Hint
Open 29 CFR Part 1926, Subpart R - Steel Erection; use 29 CFR 1926.756(a)(1) to confirm that OSHA 1926.756(a)(1) requires solid web structural members to be secured with at least two bolts per connection, of the same size and strength shown in the erection drawings, drawn up wrench-tight or equivalent before...
