During buyout reconciliation, how far should a portable ladder extend above an upper landing?
Correct Answer
B) At least 3 ft
At least 3 ft is the controlling requirement.1053(b)(1). Other choices: the distractors are related-looking contract or field terms, but they do not match the cited requirement for review item 151.
Why This Is the Correct Answer
At least 3 ft is the controlling requirement.1053(b)(1).
Why the Other Options Are Wrong
Option A: 12 in. above the upper landing
Choice A (12 in.) is rejected because 12 in. is not the OSHA ladder setup, extension, or access dimension cited here.
Option C: 18 in. above the upper landing
The trap in C is 18 in. That selection is wrong because 18 in. is not the OSHA ladder setup, extension, or access dimension cited here.
Option D: Apply the 6 ft limit to the ladder extension check
Choice D gives 6 ft. Its specific error: 6 ft is not the OSHA ladder setup, extension, or access dimension cited here.
Memory Technique
Treat ladder extension like a labeled shelf; only the matching condition belongs with At least 3 ft.
Reference Hint
Open 29 CFR 1926 OSHA Construction Standards; use 29 CFR 1926.1053(b)(1) to confirm that At least 3 ft is the controlling requirement.1053(b)(1).
