A superintendent compares the field record with the contract: at what break in elevation must access be provided when no ramp or hoist is available?
Correct Answer
A) 19 in. or more
19 in. or more is the controlling requirement.1051(a). Other choices: the distractors are related-looking contract or field terms, but they do not match the cited requirement for review item 78.
Why This Is the Correct Answer
19 in. or more is the controlling requirement.1051(a).
Why the Other Options Are Wrong
Option B: 12 in.
Choice B gives 12 in. Its specific error: 12 in. is not the OSHA ladder setup, extension, or access dimension cited here.
Option C: 30 in.
Choice C (30 in.) is rejected because 30 in. is not the OSHA ladder setup, extension, or access dimension cited here.
Option D: 48 in. of elevation change
In general project requirements, 48 in. is the wrong selection for Stair or ladder access: 48 in. is not the OSHA ladder setup, extension, or access dimension cited here.
Memory Technique
Make stair or ladder access a tabbed card: cite the exact condition, then choose 19 in. or more.
Reference Hint
Open 29 CFR 1926 OSHA Construction Standards; use 29 CFR 1926.1051(a) to confirm that 19 in.
