Final answer:
The minimum distance allowed between a spoils pile and the trench's edge is typically 3 feet to ensure worker safety and prevent soil collapse or cave-ins.
Step-by-step explanation:
The minimum distance allowed between a spoils pile and the trench's edge depends on several factors, including the stability of the soil and the specific construction site regulations. However, as a general guideline, the minimum distance is typically 3 feet.
This distance is important to ensure the safety of workers and prevent soil collapse or cave-ins.
By maintaining a minimum distance of 3 feet between the spoils pile and the trench's edge, the risk of the spoil material falling into the trench and jeopardizing the stability of the excavated area is minimized.
