As the long-lead tracker is updated, what setup ratio describes a non-self-supporting ladder?
Correct Answer
A) 1 ft out for every 4 ft of working length
1 ft out for every 4 ft of working length is the controlling requirement.1053(b)(5)(i). Other choices: the distractors are related-looking contract or field terms, but they do not match the cited requirement for review item 92.
Why This Is the Correct Answer
1 ft out for every 4 ft of working length is the controlling requirement.1053(b)(5)(i).
Why the Other Options Are Wrong
Option B: 1 ft out for every 2 ft; without the required inspection or documentation
Choice B gives 1 ft out for every 2 ft; without the required inspection or documentation. Its specific error: 1 ft out for every 2 ft; without the required inspection or documentation is not the OSHA ladder setup, extension, or access dimension cited here.
Option C: 1 ft out for every 6 ft
Choice C (1 ft out for every 6 ft) is rejected because 1 ft out for every 6 ft is not the OSHA ladder setup, extension, or access dimension cited here.
Option D: Vertical with no angle
In general project requirements, Vertical with no angle is the wrong selection for Ladder angle: the option does not produce the required Ladder angle outcome.
Memory Technique
File ladder angle under a warning sign: condition first, number or duty second, answer 1 ft out for every 4 ft of working length.
Reference Hint
Open 29 CFR 1926 OSHA Construction Standards; use 29 CFR 1926.1053(b)(5)(i) to confirm that 1 ft out for every 4 ft of working length is the controlling requirement.1053(b)(5)(i).
