After the revised drawing is issued, how far from the excavation edge should spoil be kept unless retained?
Correct Answer
A) At least 2 ft
At least 2 ft is the controlling requirement.651(j)(2). Other choices: the distractors are related-looking contract or field terms, but they do not match the cited requirement for review item 85.
Why This Is the Correct Answer
At least 2 ft is the controlling requirement.651(j)(2).
Why the Other Options Are Wrong
Option B: 6 in. from the excavation edge
Choice B gives 6 in. Its specific error: 6 in. is a different published number than the cited Spoil setback value; 29 CFR 1926.651(j)(2) supports At least 2 ft. The accepted answer is At least 2 ft.
Option C: 12 in. from the excavation edge
Choice C (12 in.) is rejected because 12 in. is a different published number than the cited Spoil setback value; 29 CFR 1926.651(j)(2) supports At least 2 ft. The cited answer is At least 2 ft.
Option D: 4 ft from the excavation edge
In general project requirements, 4 ft is the wrong selection for Spoil setback: 4 ft is a different published number than the cited Spoil setback value; 29 CFR 1926.651(j)(2) supports At least 2 ft.
Memory Technique
Use a anchor memory cue for spoil setback: the stem's condition unlocks At least 2 ft.
Reference Hint
Open 29 CFR 1926 OSHA Construction Standards; use 29 CFR 1926.651(j)(2) to confirm that At least 2 ft is the controlling requirement.651(j)(2).
