Final answer:
Excavated soil and rock must be stored at least 2 feet away from the edge of an excavation to ensure safety and stability.
Step-by-step explanation:
The correct distance for storing excavated soil and rock from the edge of an excavation is at least 2 feet. Excavated soil and rock must be stored at least 2 feet away from the edge of an excavation to ensure safety and stability. This ensures that the excess material does not create a load on the edges of the excavation, which could cause a collapse or other hazardous situation. Excavated soil and rock must be stored at least 2 feet away from the edge of an excavation to ensure safety and stability.
Occupational Safety and Health Administration (OSHA) standards are typically followed for construction and excavation work, and they specify this minimum distance for the safety of workers involved in or around the excavation site. Always refer to the latest OSHA guidelines or other local standards applicable to your region for the most accurate and legally applicable requirements.
