What is a potential risk if bookshelves are not secured in a classroom?

When bookshelves are not secured in a classroom, a significant risk involves the potential for books to fall and injure a child. In an active environment where children move around, unsteady or unsecured bookshelves can tip over easily when children pull on the books or lean against them. This scenario can lead to serious injuries, given the weight and bulkiness of the shelves, as well as the impact of falling objects. Ensuring that bookshelves are securely anchored not only protects the children's physical safety but also promotes a safer learning environment where they can engage with materials without fear of injury.
