A claims log entry raises this question: 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 100.
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.
In general project requirements, 24 in. to 30 in. is the wrong selection for Handrail height: 24 in. to 30 in. is a different published number than the cited Handrail height value; 29 CFR 1926.1052(c)(6) supports 30 in. to 37 in.
Option C: 38 in. to 45 in.
The trap in C is 38 in. to 45 in. That selection is wrong because 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.; Construction stair handrails are 30 in. to 37 in. high.
Option D: 42 in. plus or minus 3 in.
Choice D gives 42 in. plus or minus 3 in. Its specific error: 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 accepted answer is 30 in. to 37 in.
Memory Technique
Use a tab 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.
