What are the categories used in a shadow box or board?

The use of foam cutouts for tools in a shadow box or board is ideal because it serves as a visual guide that helps in organizing and ensuring the correct placement of tools. The foam cutouts are designed to match the shape and size of each tool, making it easy for personnel to see at a glance whether a tool is in place or missing. This visual management system is crucial in foreign object elimination as it minimizes the risk of leaving tools behind in aircraft or machinery. By clearly defining designated spots for each tool, foam cutouts contribute significantly to maintaining a clutter-free workspace and enhancing safety.

In contrast, while labels and tags help identify items, they do not provide the same level of immediate visual feedback regarding tool presence or absence. Tools and documents can be useful, but without the structured organization that foam offers, the risk of foreign object accumulation increases. Markings and colors, while they can enhance visual identification, do not specifically cater to the physical organization of tools as effectively as foam cutouts.
