What is the minimum distance that excavated soil must be placed from the edge of an excavation?
Correct Answer
C) 2 feet
OSHA requires excavated materials to be placed at least 2 feet from the excavation edge to prevent cave-ins caused by the additional weight and to provide adequate workspace around the excavation.
Why This Is the Correct Answer
OSHA Standard 29 CFR 1926.651(j)(2) specifically requires that excavated materials be placed at least 2 feet from the edge of excavations. This minimum distance prevents the additional weight of the spoil pile from creating surcharge loads that could cause cave-ins. The 2-foot setback also ensures adequate workspace for workers and equipment around the excavation perimeter. This is a critical safety requirement that applies to all excavations regardless of depth or soil type.
Why the Other Options Are Wrong
Option B: 5 feet
While 3 feet would provide additional safety margin, OSHA specifically requires a minimum of 2 feet, making this answer incorrect for the minimum distance asked
Option D: 1 foot
5 feet exceeds the OSHA minimum requirement and would be incorrect when asked specifically for the minimum distance required
Memory Technique
Think 'Two feet to be safe' - the minimum distance matches the number of feet humans have
