Shoring is required at depths of 5 feet or deeper when trenching in soil to ensure the safety of workers and prevent soil collapse. The need for shoring arises from the potential for soil to cave in, which can pose serious risks to individuals working in or near the trench.

At a depth of 5 feet and deeper, the likelihood of a trench collapse increases significantly due to the weight and nature of the surrounding soil. Shoring helps to reinforce the walls of the trench, providing support that mitigates this risk. Regulations and safety standards are in place to protect workers, and adhering to these guidelines is crucial for maintaining a safe work environment during excavation activities.

If the trench is shallower than 5 feet, it might not require shoring, depending on certain soil conditions and the nature of the excavation, making it essential to assess each situation individually based on the specific environmental and operational factors involved.
