What safety feature is associated with the installation of toe boards?

The correct answer relates to the function of toe boards in construction and industrial environments. Toe boards are horizontal barriers installed at the base of scaffolding or working platforms that serve a critical safety purpose. Specifically, they are designed to prevent tools, materials, and other objects from accidentally falling off the edge and causing injury to workers below. This safety feature is especially significant in high-altitude work settings, where loose items can pose serious hazards.

While electrical grounding, safety signage, and reaction time do play important roles in workplace safety, they are not the primary function of toe boards. Electrical grounding pertains to preventing electrical shock, safety signage communicates hazards or regulations, and emergency reaction time relates to how quickly one can respond to a dangerous situation, none of which are directly impacted by the presence of toe boards. Thus, preventing tools from falling is the key safety feature associated with their installation.
