Why is it important for safety nets to have a specific mesh size?

The importance of having a specific mesh size for safety nets primarily relates to the need for preventing small objects from falling through. Safety nets are designed to capture falling debris and protect workers below. If the mesh size is too large, there is a risk that smaller items—such as tools, equipment, or materials—could slip through and cause injury to individuals beneath. A well-defined mesh size ensures that the net effectively serves its purpose of providing a safety barrier, reducing the potential for accidents and enhancing overall workplace safety.

While other options might touch on certain aspects of safety net practicality, the core function revolves around the dimensions of the mesh as a protective measure against falling objects, reinforcing the critical role of safety nets in construction and other hazardous work environments.
