The deck crew inside a controlled decking zone wants to make final deck attachments while the leading edge is still active. What should the superintendent say?
Correct Answer
D) Final deck attachments and shear connectors are not performed in the CDZ
OSHA 1926.760(c)(7) states that final deck attachments and installation of shear connectors shall not be performed in the controlled decking zone. Other choices confuse safety deck attachment with final attachment or ignore the CDZ restriction.
Why This Is the Correct Answer
OSHA 1926.760(c)(7) states that final deck attachments and installation of shear connectors shall not be performed in the controlled decking zone. Other choices confuse safety deck attachment with final attachment or ignore the CDZ restriction.
Why the Other Options Are Wrong
Option A: Proceed because final fastening is safer near the edge
In metals work, Proceed because final fastening is safer near the edge is the wrong selection for CDZ final work: it answers the CDZ final work prompt with the wrong practical move.
Option B: Do final attachments only after the concrete subcontractor arrives
The trap in B is Do final attachments only after the concrete subcontractor arrives. That selection is wrong because the action skips the timing, documentation, or field-control step needed for CDZ final work.
Option C: Proceed if unsecured decking stays under 3,000 sq ft
Choice C gives Proceed if unsecured decking stays under 3,000 sq ft. Its specific error: Proceed if unsecured decking stays under 3,000 sq ft is a different published number than the cited CDZ final work value; 29 CFR 1926.760(c)(7) supports Final deck attachments and shear connectors are not performed in the CDZ.
Memory Technique
Use the phrase "problem, control, result" for CDZ final work; the result side is Final deck attachments and shear connectors are not performed in the CDZ.
Reference Hint
Open 29 CFR Part 1926, Subpart R - Steel Erection; use 29 CFR 1926.760(c)(7) to confirm that OSHA 1926.760(c)(7) states that final deck attachments and installation of shear connectors shall not be performed in the controlled decking zone.
