Answer

Brief Explanations:

In construction - related safety, trenches less than 5 feet deep or made of stable rock generally don't require a protective system as they pose less risk of collapse. Also, when a competent person examines the ground and finds no potential for cave - in, a protective system may not be needed. A trench greater than 10 feet deep usually requires a protective system due to higher risk.

Answer:

The trench will be less than 5 feet deep or made entirely out of stable rock. A competent person has examined the ground and finds no indication of a potential cave - in.
