What is the purpose of installing toe boards around the base where guard rails are placed along elevated work areas?

The correct choice is related to the essential safety function that toe boards serve in elevated work areas. Toe boards are installed at the base of guard rails to prevent tools, materials, or other objects from rolling off the edge of the platform or balcony, protecting workers below from potential hazards. This safety measure ensures that there is a physical barrier at the lower edge of the guard rail, minimizing the risk of items falling and causing injury.

Installing toe boards does not primarily enhance the height of guard rails, improve the visual appearance of the workspace, or mark hazardous areas, although these may be secondary effects. The main and critical function of toe boards is to provide an extra layer of safety by keeping items in place, thus contributing to overall workplace safety and accident prevention.
