An ironworker crosses an unprotected beam edge 18 ft above the next lower level, and the work is not connector work or initial decking in a controlled decking zone. What fall-protection trigger applies?
Correct Answer
B) More than 15 ft above the lower level
OSHA 1926.760(a)(1) requires fall protection for steel erection employees on walking or working surfaces with an unprotected side or edge more than 15 ft above a lower level, except for the connector and CDZ provisions. Other choices confuse the connector threshold, deck-completion timing, or a story count not used in this rule.
Why This Is the Correct Answer
OSHA 1926.760(a)(1) requires fall protection for steel erection employees on walking or working surfaces with an unprotected side or edge more than 15 ft above a lower level, except for the connector and CDZ provisions. Other choices confuse the connector threshold, deck-completion timing, or a story count not used in this rule.
Why the Other Options Are Wrong
Option A: Only when the edge is more than 30 ft above the lower level
Choice A (Only when the edge is more than 30 ft above the lower level) is rejected because Only when the edge is more than 30 ft above the lower level is the wrong OSHA fall-protection number for the item asked.
Option C: Only after metal decking is complete
The trap in C is Only after metal decking is complete. That selection is wrong because it tries to bypass the Steel erection fall protection checkpoint.
Option D: Only at three stories or higher
Choice D gives Only at three stories or higher. Its specific error: it leaves the work at an informal or incomplete stage, while Steel erection fall protection requires More than 15 ft above the lower level.
Memory Technique
Treat steel erection fall protection like a labeled shelf; only the matching condition belongs with More than 15 ft above the lower level.
Reference Hint
Open 29 CFR Part 1926, Subpart R - Steel Erection; use 29 CFR 1926.760(a)(1) to confirm that OSHA 1926.760(a)(1) requires fall protection for steel erection employees on walking or working surfaces with an unprotected side or edge more than 15 ft above a lower level, except for the connector and CDZ provisions.
