On a fast-track school project, what construction stair handrail height range is checked?
Correct Answer
A) 30 in. to 37 in.
30 in. to 37 in. is the controlling requirement.1052(c)(6). Other choices: the distractors are related-looking contract or field terms, but they do not match the cited requirement for review item 220.
Why This Is the Correct Answer
30 in. to 37 in. is the controlling requirement.1052(c)(6).
Why the Other Options Are Wrong
Option B: 24 in. to 30 in.
The trap in B is 24 in. to 30 in.; without satisfying the required project control. That selection is wrong because 24 in. to 30 in.; without satisfying the required project control is a different published number than the cited Handrail height value; 29 CFR 1926.1052(c)(6) supports 30 in.
Option C: 38 in. to 45 in.
Choice C gives 38 in. to 45 in. Its specific error: 38 in. to 45 in. is a different published number than the cited Handrail height value; 29 CFR 1926.1052(c)(6) supports 30 in. to 37 in. The accepted answer is 30 in. to 37 in.
Option D: 42 in. plus or minus 3 in.
Choice D (42 in. plus or minus 3 in.) is rejected because 42 in. plus or minus 3 in. is a different published number than the cited Handrail height value; 29 CFR 1926.1052(c)(6) supports 30 in. to 37 in. The cited answer is 30 in. to 37 in.
Memory Technique
Use a checkpoint memory cue for handrail height: the stem's condition unlocks 30 in. to 37 in.
Reference Hint
Open 29 CFR 1926 OSHA Construction Standards; use 29 CFR 1926.1052(c)(6) to confirm that 30 in.
