Excavated spoil is stockpiled beside a trench. What minimum setback from the edge is required unless retaining devices provide equivalent protection?
Correct Answer
A) 2 ft
Excavated material and equipment must be kept at least 2 ft from the edge of excavations, or protected by retaining devices or equivalent measures. Other choices are too close or add an unsupported larger distance.
Why This Is the Correct Answer
Excavated material and equipment must be kept at least 2 ft from the edge of excavations, or protected by retaining devices or equivalent measures. Other choices are too close or add an unsupported larger distance.
Why the Other Options Are Wrong
Option B: 6 in.
Choice B gives 6 in. Its specific error: 6 in. uses the wrong excavation protective-system trigger or exception.
Option C: 12 in.
Choice C (12 in.) is rejected because 12 in. uses the wrong excavation protective-system trigger or exception.
Option D: 4 ft
In general project requirements, 4 ft is the wrong selection for Excavation spoil setback: 4 ft uses the wrong excavation protective-system trigger or exception.
Memory Technique
Treat excavation spoil setback like a labeled shelf; only the matching condition belongs with 2 ft.
Reference Hint
Open 29 CFR 1926 OSHA Construction Standards; use 29 CFR 1926.651(j)(2) to confirm that Excavated material and equipment must be kept at least 2 ft from the edge of excavations, or protected by retaining devices or equivalent measures.
