What is the purpose of shoring in confined spaces?

Shoring in confined spaces is primarily intended to prevent cave-ins. When excavation or work occurs in confined spaces, there is a significant risk of soil collapse, especially in unstable or loose material. Shoring involves the use of supports or frameworks to stabilize the walls of the excavation, ensuring that they do not collapse, which could endanger workers inside. This safety measure is critical because a cave-in can result in serious injuries or fatalities.

While lighting, airflow regulation, and visibility are important considerations in confined space operations, they do not directly address the immediate hazards associated with soil instability during excavation work. Therefore, the primary focus of shoring is on maintaining a safe environment by preventing cave-ins.
